Short answer: the KEF LS50 Meta. It ranks #4 of 179 bookshelf speakers by sound quality, rated 4.5/5, at $1,199. The JBL L52 Classic ranks #131, rated 2.6/5, at $999, $200 cheaper, which does not close the gap in sound quality.
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 4.54 for the JBL L52 Classic. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
What the JBL L52 Classic does well: A retro bookshelf speaker with a walnut veneer cabinet, colorful foam grille and punchy upper bass. The tradeoff: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume; adding a subwoofer high-pass didn’t fix the high-frequency distortion either.
Buy the KEF LS50 Meta. It is rated higher for sound quality, and the $200 you would save on the JBL L52 Classic does not close the gap.

Measured Differences
- Tonal accuracy above the bass: with a subwoofer taking the low end, the KEF LS50 Meta scores 7.9 against 7.0 for the JBL L52 Classic on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
- Efficiency: the JBL L52 Classic is rated at 85 dB sensitivity against 83 dB for the KEF LS50 Meta, so it plays as loud with roughly two thirds of the amplifier power.
- Close enough not to matter: bass extension (43 Hz vs 45 Hz, 10 dB down).
