Short answer: the KEF R3 Meta if sound quality matters most, the Fosi Audio SP601 if price matters most. The KEF R3 Meta ranks #10 of 222 bookshelf speakers, rated 4.6/5, at $2,499.99. The Fosi Audio SP601 ranks #201, rated 2.7/5, at $399.99, $2,100 cheaper.
The KEF R3 Meta is the better-sounding choice. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. The tradeoff: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
The Fosi Audio SP601 is the deeper-bass option. A budget bookshelf speaker with a 6.5 inch woofer and respectable bass that improves noticeably with simple EQ. Its bass reaches about 59Hz before falling 3dB, against 76Hz for the KEF R3 Meta. Watch for: An unusually erratic, up-and-down frequency response (a scooped midrange followed by an upper-mid bump, a dip, another small bump, then a strong 3-4dB peak around 4-7kHz) makes the speaker’s overall character genuinely hard to characterize: the reviewer compared the experience to a similarly disliked model, the Triangle Borea BR03, which has a comparably inconsistent response.
Buy the KEF R3 Meta if sound quality matters more than the price. Buy the Fosi Audio SP601 if the price matters more than sound quality.
