The FiiO SA1 is a powerful active speaker that impresses with high-quality components and versatile connectivity options. Equipped with a 3.5-inch wood fiber woofer and a ¾-inch tweeter made from an aluminum-magnesium alloy, the speakers deliver a detailed sound profile with warm mids and clear highs. The electronic two-way crossover precisely separates the frequency ranges, reduces distortion, and ensures optimized sound reproduction. A bass reflex design allows for low-frequency reproduction down to 65 Hz, rounding out the balanced sound profile. A digital Class D amplifier from Texas Instruments provides 20 W for the woofer and 5 W for the tweeter per channel, ensuring powerful and precise playback. The four-channel amplifier unit drives the drivers independently, guaranteeing the highest sound quality. A variety of connection options allows for both wired and wireless playback. Support for high-resolution Bluetooth with LDAC enables wireless streaming and ensures lossless playback in high quality. An integrated phono preamplifier allows for direct connection of turntables, while an additional subwoofer output enables expansion of the sound system. Control is via physical knobs or the included infrared remote control. The FiiO Control App allows for sound profile adjustments through a 31-band equalizer and selection from eight preconfigured sound modes. The robust MDF cabinet with acoustically optimized design minimizes unwanted resonances and enhances sound precision. Automatic standby and wake-up functions ensure energy-efficient operation. With thoughtful design, high-quality materials, and a multitude of features, the FiiO SA1 offers a powerful solution for demanding audio applications.
