FiiO is known for making excellent audio gear, but mostly for headphones and portable DACs. The SP3 speakers are their attempt to bring that same precision to a desktop setup. They succeed. The key is the Texas Instruments digital amplifier, which runs four independent channels—30 watts each to the woofers and 10 watts each to the tweeters. That separation matters. It keeps the bass clean and the highs crisp, even when you push the volume.

The acoustic design is clever for such a small box. A 3.5-inch carbon fiber woofer handles the low end, while a 1-inch silk tweeter takes the treble. The waveguide and S-shaped port extend the bass response without making it boomy. At low volumes, the imaging stays solid. You get a clear sense of where sounds sit in the stereo field, which is rare for a 2.35-liter enclosure. The liquid metal die-cast chassis keeps things rigid and reduces vibration.

One thing to note: these are shelf-mounted speakers designed for nearfield listening. They work best on a desk, within a few feet of your ears. They won’t fill a large room with authority. But for a focused listening session or gaming setup, the SP3 delivers a tight, controlled sound that outperforms most powered speakers in this size class.
