Short answer: the KEF LS50 Meta on measured sound quality, the Jamo S7-15B on price. The KEF LS50 Meta ranks #4 of 179 bookshelf speakers, rated 4.5/5, at $1,599.99. The Jamo S7-15B ranks #53, rated 3.7/5, at $299, $1,300.99 cheaper.
The KEF LS50 Meta is the more accurate option. An iconic compact KEF speaker with highly accurate sound, pinpoint imaging and a coaxial driver that keeps tone even across the room. Its measured preference score, a predictor of how neutral it sounds, is 5.74 against 4.52 for the Jamo S7-15B. The catch: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
Why pick the Jamo S7-15B: Living room bookshelf speakers with a distinctive tilted cabinet, a fabric dome tweeter and magnetic grilles. The tradeoff: Despite the 45Hz snapshot extension metric, Jamo specifies a conservative 71Hz +/-3dB bandwidth, so deep bass needs support.
Buy the KEF LS50 Meta if sound quality matters more than the price. Buy the Jamo S7-15B if the price matters more than sound quality.
