Fosi Audio SP601 Review: Budget Bookshelf Speakers That Punch Above Their Price

Building a budget HiFi setup gets confusing fast once you're pricing out speakers, an amplifier, and cables separately. Fosi Audio is a brand I mostly associate with its compact desktop amplifiers, so when I saw the SP601 Bookshelf Passive Speakers ($399.99) listed on the site, I wanted to see whether the company's first real step into speakers holds up.

What's Inside the SP601

The SP601 pairs a 1.5-inch silk dome tweeter with a 6.5-inch Hybridcone composite woofer that combines a paper cone with an aluminum alloy layer, a combination aimed at keeping the tonality balanced rather than overly bright or boomy. On paper, that's a sensible driver pairing for a bookshelf speaker in this price range.

Power Handling and Sensitivity

Fosi Audio rates the SP601 at 80W RMS with 160W peak power, 86dB sensitivity, and a 4-ohm nominal impedance. Because these are passive speakers, they need an external amplifier to actually play anything — worth keeping in mind if you're shopping speakers and amp separately, though it also means you can pair them with whichever Fosi Audio amp (or any other amp) fits your setup and room size.

Cabinet Design and Build

The cabinet uses a bass reflex design with a precision-cast aluminum waveguide, finished in white with metallic orange accents rather than the usual all-black bookshelf look. The magnetic wooden frame grille is dust-proof and just pops on and off magnetically, which is a nicer touch than the friction-fit grilles a lot of budget speakers use. Around back, dual-mode binding posts accept both banana plugs and bare wire, so you're not locked into one type of speaker cable.

What I Liked

• Driver combination (silk dome tweeter + Hybridcone woofer) aimed at balanced sound rather than boosted bass
• Magnetic grille is genuinely convenient compared to friction-fit alternatives
• Flexible binding posts that take banana plugs or bare wire
• Distinct white-and-orange finish if you don't want another plain black box

What Could Be Better

• These are passive speakers, so you'll need to budget for a separate amplifier
• At $399.99, they sit above Fosi Audio's usual budget-amp price range, so it's a bigger commitment than the brand's smaller products

Final Verdict

If you already own (or are planning to buy) an amplifier and want a bookshelf pair with a sensible driver setup and a design that stands out a little, the SP601 is worth a look.
