The SP3 Series is equipped with a 3.5-inch carbon fiber woofer, larger than most in its category, enabling an impressive sound output for a compact desktop speaker. Larger woofers offer superior dynamics, wider soundstage projection, and overall improved audio characteristics. Whether watching movies or listening to music, this woofer can reproduce a full-bodied sound even at high volumes.

Carbon fiber is renowned for its high strength, rigidity, and low weight—ideal for speaker drivers. Its lightweight nature allows rapid response, while its rigidity reduces unwanted distortions by minimizing secondary vibrations. This results in faithful sound reproduction, immersing listeners deeper into a high-fidelity experience.

Each carbon fiber layer in the SP3 Series measures just 0.007 mm—about the thickness of a single hair. The woven fiber construction enhances sound quality by ensuring a seamless cone, reinforcing durability, and resisting damage from prolonged use.

High-Frequency Excellence

In a desktop speaker, the tweeter plays a vital role in preserving musical details, harmonic overtones, and treble clarity. Unlike conventional desktop speakers that use a ¾-inch tweeter, the SP3 Series features a 1-inch tweeter capable of reaching up to 35 kHz. 

The copper-clad KSV aluminum voice coil in the tweeter ensures ultra-high frequencies remain clear even at elevated volumes, delivering exceptional treble performance. The result is crisp highs, improved off-axis listening, and an immersive listening experience where even the subtlest instrument vibrations can be heard.

Powerful and Robust Audio

To drive the 3.5-inch carbon fiber woofer effectively and fully unlock the SP3 Series' potential, the engineering team developed an asymmetric magnetic circuit system. A strategically placed additional magnet at the center enhances the strength of the generated magnetic field, reaching a flux density of 1.2 Tesla. 

This design provides the necessary power for dynamic sound reproduction. The asymmetric internal and external magnetic circuits also help reduce distortion across all frequency ranges, ensuring consistently clear sound regardless of the music genre.

Precision-Engineered Sound

After extensive testing, FIIO engineers developed the innovative “double-diffused S-shaped bass reflex tube.” This design achieves a balance between compact size and high-performance sound output.

- The narrower cross-section of the bass reflex tube helps maintain a small enclosure size.

- The carefully crafted “S” shape ensures smooth airflow and reduces turbulence.

- Specially applied damping at the tube’s inlet and outlet minimizes noise, delivering deep and clear bass.

The SP3 Series effortlessly immerses users in music, accurately reproducing sound effects with remarkable precision.

For an optimal listening experience, the FIIO SP3 Series is designed to project sound waves efficiently toward the listener. The tweeter is precisely angled to maintain a 0 to ±15° off-axis listening range with minimal loss, ensuring flexibility in speaker placement. 

Additionally, the horizontal stripe design in front of the tweeter helps distribute sound waves more effectively, enhancing the soundstage perception and replicating the feeling of being in a large concert hall.

Seamless Wireless Connectivity

Featuring the Qualcomm QCC5124 Bluetooth chipset, the SP3 BT delivers stable and consistent high-bit-rate processing through its dual-core design.

- Bluetooth 5.0 for reliable wireless transmission

- High-resolution codec support: LDAC, aptX Adaptive, AAC, and more

With LDAC support, users can enjoy bit rates up to 990 kbps, ensuring rich detail and superior audio quality.

Versatile Input Options

The SP3 BT integrates modern and traditional connectivity options, including Type-C, COAX, and OPTICAL inputs, making it easy to link the speakers with various devices. 

Customizable Sound to Fit Your Taste

Supporting a 10-band parametric EQ, the SP3 BT allows users to fine-tune their sound using the FIIO Control App or FIIO Music mobile apps. The app provides options to adjust EQ bands, customize device names, and select preferred Bluetooth codecs.

Adaptive Power Management

The SP3 BT features a standby mode that automatically activates if no input signal is detected for 20 minutes. Once a signal is detected, the speaker resumes playback, ensuring energy efficiency and convenience.

Advanced Audio Engineering

The SP3 Series employs an active 2-way crossover system, directing high frequencies to the tweeter and low frequencies to the woofer. This setup minimizes signal interference, enhancing audio purity and reducing distortion.

- 3.4 kHz crossover frequency for optimal woofer and tweeter performance

- Second-order 2-way filter circuit for precise crossover control

- 100W power supply capacity for an unparalleled sound experience

Superior Amplification for Pristine Audio

The SP3 Series incorporates two Texas Instruments (TI) 3118 Class D amplifiers, known for high efficiency and low noise, ensuring clean audio output. 

With an active 4-channel crossover system, each driver operates independently, reducing interference and improving signal conversion efficiency. High-quality Nichicon capacitors (4700µF each) further stabilize the power supply, minimizing unwanted fluctuations.

Compact Yet Powerful

With a total volume of just 2.35 liters, the SP3 Series is designed to save desk space without compromising on sound performance.

- Die-cast liquid metal housing minimizes resonance for improved audio quality

- Horizontal stripes on the front panel reinforce cabinet stability, preventing vibrations at high volumes

- Exclusive 7-degree tilted stand optimizes speaker positioning for near-field listening

- Rubberized feet act as shock absorbers, preventing unwanted vibrations from affecting sound output

Intuitive RGB Lighting Effects

The SP3 BT features an RGB lighting system that indicates current speaker status. Various lighting effects can be customized to enhance the listening experience.

Designed for Hi-Fi

To ensure optimal sound positioning, FIIO developed an exclusive 7-degree angled stand based on extensive listening tests.

- Silicone base absorbs vibrations, reducing sound distortion

- Optimized tilt ensures accurate sound projection for near-field listeners

Understanding user needs, FIIO provides high-quality accessories, including standard 8-pin speaker connection cables and a 3.5mm-to-RCA input cable. These cables are made of high-purity monocrystalline copper with shielding for interference-free sound transmission.

Certified for High-Resolution Audio

The SP3 Series meets Japan Audio Association (JAS) and Consumer Electronics Association (CEA) Hi-Res Audio certification standards. The SP3 BT model is further certified for Hi-Res Wireless Audio, ensuring superior sound fidelity.
