It brings Bluetooth 6.0, true lossless codecs, and a fully differential 24-bit R2R DAC into a single, compact component you can drop into an existing system. Use it with active speakers, a favorite amplifier, or an external DAC. Once it’s in your chain, you can stream freely and hear your library in a new way. Qualcomm Bluetooth and lossless codecs Featuring Qualcomm’s flagship QCC5181 chip, the BR15 R2R supports LDAC, aptX Adaptive, and aptX Lossless. You get up to 2.1Mbps of wireless bandwidth—enough for CD-quality, lossless transmission with stable detail retrieval. Pair your phone or tablet and listen without feeling tied to your chair. LDAC and aptX Lossless for modern listening If your speakers or amplifier don’t support advanced wireless codecs, the BR15 R2R fills that gap. With LDAC and aptX Lossless decoding onboard, streaming video, films, and long listening sessions take on a cleaner, richer character. It brings modern wireless standards to older chains, and gives newer chains room to breathe. Bluetooth 6.0 with extended range Bluetooth 6.0 brings stronger interference resistance, lower latency, and a wider usable range. The external antenna keeps the signal locked even when you’re moving around the room. You can cue tracks from the couch, or from across the space, without dropouts interrupting the moment. Fully differential 24-bit R2R DAC At the center of the BR15 R2R is a proprietary quad-channel, fully-differential R2R DAC. Each channel uses 48 precision thin-film resistors—192 total—with 0.1% accuracy and low temperature drift. The result is a darker noise floor, a smoother background, and the kind of texture R2R fans love. You can run the DAC in NOS or OS mode, depending on the character you prefer. Bluetooth, USB, coaxial, and optical decoding The BR15 R2R fits into all kinds of listening chains. You can switch between Bluetooth, USB, and SPDIF (coaxial/optical) whenever you need. Hook up a phone, a laptop, a CD transport, a television—whatever you use day to day. The device adapts quickly and doesn’t anchor you to one source. Analog and digital outputs for easy pairing Two RCA outputs, one XLR output, and both optical and coaxial digital outputs give you a lot of freedom. Connect to active speakers, feed an external DAC, or run directly into an amplifier. It’s simple to reconfigure as your system changes. Global PEQ and AUTO EQ tools A global 10-band PEQ lets you shape the sound across all modes. Through FIIO’s app, you can load presets or build your own curves. You can simulate or correct the frequency response of your gear, and export or share curves with others. AUTO EQ makes the process even easier—just sync your headphone’s profile and target curve, and let the algorithm handle the fine points. Fully-balanced signal path From the R2R DAC through the low-pass filter and volume control, the entire signal chain is fully-balanced. Noise stays low, distortion remains controlled, and dynamics stay wide. A built-in pop-noise suppression system keeps power-on and power-off transitions quiet. AC/DC dual power supply support Inside, a high-quality switching supply keeps the BR15 R2R stable under normal use. You can also plug in an external 5V DC supply—ideal if you keep a linear power supply on hand. When DC power is connected, the device automatically switches to it, letting you explore different power profiles and sonic characteristics. Custom color display A 1.47-inch LCD screen gives you track information, volume, sampling rate, EQ status, and more. When paired with a compatible Bluetooth source, you’ll also see lyrics. It’s a clean way to check your chain at a glance. Control from near or far Dual knobs and a front display make close-range operation quick and intuitive, especially at a desk. For listening across the room, you can use the included infrared remote or the FIIO Control app to make adjustments without getting up.

FiiO SP3 BT Active Hi-Fi Desktop Bluetooth Speaker 3.5-inch carbon fibre mid-woofer CrossoverAsymmetrical internal and external magnetic circuits Directional acoustic waveguides Double diffused S-shaped port tube 1-inch silk tweeter TI power amplifier 2x30+2x10W output power Qualcomm QCC5124 Bluetooth chip Supports high-resolution Bluetooth codecs including LDAC/aptX Adaptive Hi-Res Wireless certified Tiny volume of 2, 35L Die-cast liquid metal enclosure LED lighting effects Exclusive stand with 7-degree elevation High-quality exclusive cables True audiophile quality The SP3 Series uses a 3.5-inch carbon fibre woofer that is larger than typical products in this class, producing a big sound for such a small desktop speaker. These larger woofers have an inherent advantage over smaller woofers in terms of dynamics, projection of a larger soundstage and other sonic characteristics. Whether for films or music, this woofer is capable of expressing the size of the sound even at higher volumes. Carbon fibre is extremely strong and rigid, yet lightweight - the ideal characteristics for a speaker driver. The low weight of carbon fibre allows the woofer to transient quickly, while the high strength and stiffness of carbon fibre reduces non-linear distortion by minimising unwanted secondary vibrations as the driver moves during sound production. Overall, the carbon fibre material of the woofer contributes to a faithful sound reproduction and lets you immerse yourself even more intensively in your high-fidelity experience. Each carbon fibre in the SP3 series is only 0.007 mm thick - as thick as a single hair. These fibres are woven together, which helps to improve sound quality by ensuring a wrinkle-free cone and making the cone stronger and more resistant to cracking after prolonged movement and use of the driver. "To achieve a better sound, we use a special damping rubber for the woofer to obtain a transparent sound. This allows for realistic and detailed vocal reproduction as well as a very controlled and fast bass." Allen Chief Expert of FIIO Audio R&D Centre Treble performanceIn an active desktop speaker, the tweeter often plays a crucial role in the reproduction of fine musical details, instrumental overtones and overall treble resolution. Unlike many other active desktop speakers that use a ¾-inch tweeter, the SP3 series utilises a 1-inch tweeter that can produce frequencies of up to 35 kHz. The tweeter's copper-clad KSV aluminium voice coil ensures that ultra-high frequencies are not compressed even at high volumes - the result is better high-frequency reproduction even with off-axis listening and high-resolution treble with a natural timbre. With the SP3 series, you can hear even the most subtle vibrations of instruments. Robust performance To ensure that the 3.5-inch carbon fibre woofer produces really powerful bass and that the SP3 series can unfold its full potential, the development team has developed an asymmetrical system of internal and external magnetic circuits. An additional magnet has been placed in the centre of the SP3 Series to form an inner and outer magnetic circuit, improving the strength of the magnetic field generated and allowing a magnetic flux of up to 1.2 Tesla. This is the powerful driving force behind the driver that gives the SP3 Series its dynamic sound. In addition, the asymmetrical internal and external magnetic circuit systems help to reduce non-linear distortion across all frequencies, so that good sound is always available, no matter what music you listen to. Captivating sound that starts with the details Double-diffused S-shaped bass reflex tube After dozens of different designs, FIIO engineers finally developed the innovative "double-diffused S-shaped bass reflex tube" that allows the SP3 Series to achieve its goals of being compact while still producing high-quality sound. Firstly, this bass reflex tube has a much smaller cross-section than typical bass reflex tubes, allowing the SP3 Series to maintain a small volume. Secondly, FIIO engineers have carefully designed the "S" shape of the bass reflex tube to maximise smooth airflow and minimise turbulence. Finally, damping has been specifically applied to the inlet and outlet of the tube to reduce audible noise and ensure pure, robust bass quality. All in all, the SP3 Series will effortlessly immerse you in your music thanks to its ability to accurately reproduce sound effects. Create your exclusive hi-fi theatre For outstanding sound quality, the FIIO SP3 series has been specially tuned and designed to ensure that the sound waves reach the listener in the best possible way. The tweeter is precisely angled so that the sound waves are transmitted to the listener in an off-axis range of 0 to ±15° with essentially no loss, so that the listener is not tied to a specific position and speaker placement becomes more convenient. In addition, the horizontal stripe pattern in front of the tweeter has been designed to allow the sound waves emanating from the tweeter to propagate better in the room, which significantly improves the perceived soundstage and better conveys the illusion of actually being in a large concert hall. Wireless transmission, always online Qualcomm QCC5124 Bluetooth chip The SP3 BT uses the Qualcomm QCC5124 Bluetooth chip, which is able to process high bit rates stably and consistently thanks to its dual DSP and dual-core design. *Bluetooth 5.0 version Wireless freedom, but with wired-level sound quality The FIIO SP3 BT supports multiple high-resolution Bluetooth codecs such as LDAC/aptX Adaptive/AAC, giving you the freedom and flexibility to choose. When using LDAC, you can experience a high bit rate of up to 990kbs so you can hear every detail of your music. *All codecs supported by the SP3 BT can be found in the technical specifications. Now the mood is right to play music The FIIO SP3 BT features new Type-C/COAX/OPTICAL inputs that allow easy communication between your source and the speakers. Play your music easily and instantly, whether you use the modern USB Type-C connection or the proven COAX and OPTICAL inputs. Your speakers, your sound Supports 10-band parametric EQ To further enhance your SP3 BT listening experience, the speakers have been designed to work fully with the FIIO Control APP/FIIO Music mobile apps. After a successful Bluetooth connection, the mobile apps allow you to fine-tune your sound, e.g. customise the device name and set the Bluetooth codecs to be used. The biggest highlight of the app, however, is the 10-band parametric EQ, which allows you to adjust the Q value, gain and other parameters for each band. Dynamic or quiet, just as you like The SP3 BT has a standby wake-up function, i.e. if no signal input is detected within 20 minutes, the SP3 BT automatically switches to standby mode; if a signal input is detected, the SP3 BT automatically switches to playback mode. An automatic playback pause function makes the speaker more intuitive for your needs.The audio expertise that leads the way to great sound Active 2-way crossovers In professional audio products, an active crossover is used to split the frequencies in a sound signal, with the higher frequencies going to the tweeter amplifier and then to the tweeter, and the lower frequencies going to the woofer amplifier and then to the woofer. In this way, interference between the signals sent to different drivers is avoided. The FIIO SP3 Series uses an active crossover with a crossover frequency of 3.4 kHz, specifically selected to maximise the performance of the tweeter and woofer. The SP3 Series utilises a second order active 2-way filter circuit to more accurately control the crossover frequency and ensure that the signals sent to each driver are more effectively isolated, resulting in less intermodulation distortion, avoiding driver overload and significantly improving the efficiency of the power delivered. The SP3 Series power supplies can deliver up to an astonishing 100W, giving you a truly thunderous sound experience that is unrivalled in its class. Turn it up, turn it up! One of the most important parts of an active desktop speaker is the amplification. The SP3 series is equipped with two Texas Instruments (TI) 3118 Class D amplifiers, which are highly efficient, have a low noise floor and ensure the purity of the audio signal. FIIO's experienced research and development team has developed an active 4-channel crossover system for the SP3 Series, so that each driver has its own independent circuitry for less interference and greater efficiency in converting signals into sound. A robust power supply is all that is needed to realise the full potential of the high-end SP3 Series components. The R&D team spared no expense and equipped the SP3 series with two large Nichicon capacitors with a capacity of 4700uf each. These capacitors contribute to a more stable and cleaner power supply by helping to minimise ripple in the amplifier supply. Sound and size Tiny volume of 2.35 litres to free up space on your desk, the SP3 series has been designed to fit all the necessary components in the smallest possible housing - resulting in a total volume of just 2.35 litres. The SP3 series gives you the flexibility to create a comfortable desktop setup with plenty of space. Die-cast liquid metal housing The SP3 series has a housing made of high-strength die-cast aluminium. The inner walls of the housing are carefully and evenly manufactured to reduce resonances and thus improve the sound quality. The horizontal strips on the front of the speaker serve to stiffen the cabinet and help to avoid unwanted strong vibrations at high volumes. Exclusive stand with 7 degree tilt For an optimal listening experience, the axis of the tweeter should not be more than 15 degrees away from the ear. The SP3 series comes with stands that are raised by 7° to bring the speakers into this perfect position. In addition, the feet of the SP3 series are made of rubber, which prevents a hard connection between the speaker and the table top and acts as a shock absorber. Find out the status of the speakers at a glance To make it easier to recognise what the speakers are currently doing, the development team has set up an RGB lighting system that clearly displays the current status of the speakers. There are also various RGB lighting effects that you can customise to further enhance the listening experience. Closer to your ear and your heart Exclusive stand with 7-degree elevation As usual in the professional audio world and to ensure a better listening experience in the near field, the tweeter should be at ear level and the tweeter axis should not be more than 15 degrees away from the ear. "Therefore, we have developed an exclusive stand with a 7-degree tilt angle especially for the SP3 series. We conducted listening tests with 5-15° and 7-15° stands with the listener 1 to 1.2 metres away from the speaker. In these tests, we concluded that a stand with a 7-degree tilt angle provides the most accurate sound for near-field listeners. In addition, the stand is made of silicone, which acts as a shock absorber by creating a soft surface between the SP3 Series and the desk, reducing sound distortion from vibrations when the speaker is producing sound." Allen Chief Expert of FIIO Audio R&D Centre Consistent FIIO quality Standard 8-pin primary and secondary speaker connection cable Standard 3.5mm to RCA input cable FIIO has always adhered to the principle of user-centricity. In discussions with users, we have found that some well-known speaker brands do not include standard speaker connection cables or input cables, requiring users to purchase an additional cable. This resulted in a poor user experience. As a well-known accessory supplier in the Hi-Fi industry, FIIO provides a large number of Hi-Fi users with thoughtful product experiences with solid materials and rich accessories. Based on market feedback, the SP3 series comes standard with a 3.5mm RCA input cable and an 8-pin primary and secondary speaker connection cable, both made of monocrystalline copper and finished with a shielding layer. These cables are plug-and-play ready so that the user can enjoy the professional hi-fi sound of the SP3 series without any worries. Certified Audio The SP3 has been certified by the Japan Audio Association (JAS) and the Consumer Electronics Association (CEA) with Hi-Res Audio, and the SP3 BT is even certified for both Hi-Res and Hi-Res Wireless Audio. You can be sure that the speakers will reproduce your music faithfully and with high fidelity. Technical data: Speaker type: Active Bluetooth desktop speaker with high fidelity Dimensions: Approx. 163x120x132mm (without base) Approx. 170x120x132mm (including 0° flat base) Approx. 182x120x132mm (including 7° angled base) Bluetooth chip: Qualcomm QCC5124 Bluetooth codecs: LDAC/aptX Adaptive/aptX HD/aptX LL/aptX/AAC/SBC Weight: primary speaker weight 1950g, secondary speaker weight 1780g Cabinet material: aluminium alloy Cabinet manufacturing method: liquid die-casting Crossover: 2-way Frequency response: 65Hz-20kHz (±2dB) Speaker impedance: 8Ω Speaker sensitivity: 85dB (1Vrms)@1kHz Output power: 2x30W (woofer)+2x10W (tweeter) Inputs: RCA/AUX/Type-C/COAX/OPT Length of primary and secondary speaker connection cables: Approximately 2.5m RGB status lights: LDAC: Pulsating white light aptX Adaptive: Pulsating green light aptX HD: Pulsating yellow light aptX/aptX LL: Pulsating purple light AAC: Pulsating cyan light SBC: Pulsating blue light SP3 BT What`s in the box: 1x primary speaker 1x secondary speaker Mains adapter AC mains cable RCA (RCA) to 3.5mm audio cable Connection cable for primary and secondary speakers 2.5 m long 2x pairs of rubber feet (0° and 7°) Instructions for use

To achieve incredible sound even in larger rooms, FiiO has carefully refined every detail of the driver, from the diaphragm material to the magnetic circuit system, the driver suspension, and the voice coil. This careful construction ensures outstanding rigidity and control, allowing the SP5 to reproduce intense, dynamic music without the slightest distortion. The result is deep and powerful bass for a rich, full-bodied sound that is both precise and responsive. Every little detail is reproduced accurately and impressively. Linear composite fiber diaphragm This diaphragm has excellent durability and strength, which prevents breakup at high power and keeps distortion in the playback frequency range below 1%. Symmetrical magnetic circuit Provides a magnetic field strength of more than 1.2 Tesla. Large-diameter, long-throw voice coil A large 30 mm long-throw voice coil, rare in its class, reduces moving mass so it can move enough to deliver powerful, dynamic reproduction. NBR rubber suspension Its high flexibility and fatigue resistance, as well as its spiral grooved design, prevent nonlinear distortion in music with strong impulses. *Want your speakers to perform at their best faster? We recommend playing music continuously for about 48 hours (“break-in”). After that, you will find that the sound is even more pleasant. 1-inch soft silk dome composite tweeter for clear and smooth highs The SP5 tweeter is not only made of high-quality materials, but is also acoustically perfect in design. The FiiO development team has developed an innovative soft, hemispherical structure inside the dome that precisely absorbs harmful harmonics from the rear of the diaphragm. The result is significantly purer and more transparent highs. To achieve the high-end hi-fi goals of low resonance and high power handling, the SP5 features a groundbreaking large cavity design on the rear. This innovative design makes it possible to lower the high frequencies to an impressive 800 Hz. It also ensures that the driver can relieve pressure even at frequencies above 20 kHz, which drastically reduces unwanted resonances. Cooling technology for the tweeter magnet circuit The SP5's high-frequency reproduction reaches a new level of sophistication, becoming silky smooth and pleasantly fluid. It effortlessly brings out every subtle detail in your music. The SP5's tweeter uses a precisely engineered waveguide to optimize near-field listening. It precisely controls the direction of sound and, together with the horizontal stripes on the front, significantly expands the soundstage. *Cooling technology for the tweeter magnetic circuit – a cooling and damping system with magnetic fluid for a better extended and resolved high frequency range. Independent 120W power supplies Ensure that the main and secondary speakers have ample power without interfering with each other. FiiO's self-developed high-performance switching power supply delivers a robust 120W of power to each SP5 speaker. Thanks to these ample power reserves, the speakers can effortlessly reproduce any type of dynamic music, while universal voltage support allows you to take your speakers anywhere. A clean power supply is essential for true high-fidelity sound. The SP5 uses a multi-stage rectification and filter architecture to independently power the output stage, significantly reducing interference. A revolutionary transformer resonance system converts a single power source into a dual symmetrical power supply, providing clean, stable energy to the critical front-end circuits. This design eliminates DC-DC noise at the source, resulting in an excellent signal-to-noise ratio and a darker background with clearer details. The intelligent power-saving mode* has been carefully designed for energy efficiency and features extremely low standby power consumption. The speakers activate instantly when music playback begins and are always ready to deliver breathtaking sound. *Energy-saving mode is enabled by default and features an automatic standby and activation function. You can disable this feature in the app if you do not want the device to automatically enter standby mode. 60 W*2+20 W*2 independent four-way power Precise and powerful energy transfer The SP5's main and secondary speakers each contain a renowned Texas Instruments (TI) TPA3116D2 Class D digital stereo amplifier that drives each channel independently. The amplifiers enable an output power of up to 60 W*2 for the woofers and up to 20 W*2 for the tweeters. The TPA3116D2 is also designed for reliability and features built-in protection against short circuits, overheating, and voltage fluctuations. In the event of an overload, the processor is alerted to prevent damage. XLR balanced input Pro audio DNA The balanced XLR interface is widely used in professional audio equipment. Compared to standard RCA jacks, its main advantage is high noise immunity, making it ideal for long-distance transmission while delivering a higher-quality audio signal. The SP5 features a professional balanced XLR input. It uses three-pin differential transmission, where hot (+) and cold (-) signals are sent simultaneously. The special ground cable blocks external interference, eliminating over 90% of common-mode interference. This completely eliminates interference even when transmitting signals over long distances. *If the main speaker uses the XLR input, the secondary speaker can only use the XLR input. **When using the XLR input, RCA audio cables are not required. ***The XLR input supports both XLR3 and TRS 6.35. ****The XLR input supports independent volume control. Low-noise, high-precision electronic volume control Equipped with a robust composite encoder and a precise coreThe SP5 uses the high-precision, low-noise NJW1195A electronic volume control in each speaker. This volume control features an electronic potentiometer with a resistive ladder that has low imbalance and low output noise of typically -118 dBV (1.26 µVrms). It also features an extremely low distortion rate of only 0.0003%. The wide volume range from +31.5 dB to -95 dB can be adjusted in fine steps of 0.5 dB, enabling precise volume control. By using a chip typically found in high-end headphone amplifiers and combining it with carefully tuned circuits, the SP5 achieves a signal-to-noise ratio of 100 dB. Bluetooth version V5.1 Supports high-resolution Bluetooth codecs for excellent wireless sound The SP5 is powered by a Qualcomm QCC5125 Bluetooth chip, which offers 24-bit audio processing and advanced DSP for an enhanced listening experience.

The bass extension function overcomes this limitation by utilizing technologies that go beyond the physical limitations of the hardware. A special circuit extends the frequency response in the low frequency range, providing stronger bass, faster transients, and a deeper sound stage, all of which result in richer, deeper, and more layered bass. When listening to music, you can choose how deep you want the bass extension to go to suit different music genres. For movies and games, bass extension can enhance the impact of the bass for an even more immersive experience. -2 dB/0 dB/+2 dB Treble Adjustment +2 dB: This setting boosts the high frequencies to improve the presence and detail of the sound. For example, when mixing, using +2 dB makes it easier to hear the subtle details in each track. This is ideal for music genres where high frequency clarity is crucial, such as string and electronic music. -2 dB: This setting reduces the energy of the high frequencies to prevent the sound from becoming shrill or hissing. This is ideal for listening to classical music or any other music that requires a natural sound, or in any environment where you need to reduce unwanted reflections. 0 dB/+3 dB/+6 dB Bass Adjustment The bass boost function amplifies frequencies below 100 Hz for richer, more impressive bass. It can also be used to reduce interference from room standing waves and balance the sound.

Fine-tune the sound by adjusting the frequency response curve with a 10-band PEQ based on FiiO's proprietary algorithms. Housing made of 650°C liquid aluminum of aviation quality, manufactured using a die-casting process that significantly reduces resonance Each SP5 speaker enclosure is made from a single 10 kg block of aluminum, melted and cast at 650°C. This state-of-the-art metalworking pushes the boundaries of acoustic physics. • The high-density aluminum is 300% stiffer than MDF wood enclosures. Combined with a uniform inner wall structure, unwanted resonances are significantly suppressed. • A precision manufacturing process reduces the weight of the enclosure by 30%, from 10 kg to 7 kg. This allows for a larger internal volume in a smaller speaker, which improves low-frequency performance. • Natural heat sink: The aluminum naturally dissipates heat, ensuring stable performance at high power levels. • Electromagnetic shielding: The metal shell provides electromagnetic shielding for clearer sound. Diffuser-shaped horizontal stripes and a curved cabinet structure that prevents standing waves effectively eliminate unwanted vibrations. The dimensions of the SP5 cabinet have been carefully calculated to prevent standing waves, and the drivers are angled for perfect phase alignment. In addition, the smooth, rounded edges minimize sound diffraction.

It also solves a structural problem of Class D amplification by eliminating the load dependency inherent in this technology. In addition, the aluminium housing isolates the power supply from the amplifier section, preventing crosstalk. A flexible amplifier The V3 amplifier is designed to be integrated into various configurations. For example, you can easily switch between RCA and XLR inputs using the switch on the front. You can also adjust the gain of the RCA input between 25 dB and 31 dB. And if you want a different sound colour, you can swap the TI NE5532 OPAs via DIP8 mounting. A revised cooling system To prevent overheating and thus ensure the longevity of the amplifier, Fosi Audio has developed an innovative ventilation system in addition to the traditional heat sink on the amplifier chip. The ventilation system is designed to prevent the ingress of dust without compromising cooling, ensuring impeccable sound quality combined with increased reliability. What`s in the box1x V3 Mono AMP 1x 48V 5A power supply 1x operating instructions
