Short answer: the KEF Q Concerto Meta for better sound quality, the JBL XPL-90 for the lower price. The KEF Q Concerto Meta ranks #11 of 131 bookshelf speakers at $1399.99. The JBL XPL-90 ranks #101 at $1298, $101.99 cheaper.
What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.
What the JBL XPL-90 offers: Nearly ruler-flat on-axis response up to 1kHz with even horizontal directivity until the tweeter beams above 10kHz. The reviewer found real strength with vocals and simpler instrumentation, calling it “the first speaker I have liked that has some clear response errors” and “an enjoyable speaker” despite the flaws. Titanium tweeter and internal Monster cable wiring reflect JBL’s higher-end late-1980s engineering. Watch for: Crossover region peaking around 3kHz and treble peaking above 10kHz color the top end, and poor vertical directivity means the tweeter needs to be at ear level. Distortion rises at 96dB SPL, especially around 3kHz. Long discontinued; only available on the used market.
Buy the KEF Q Concerto Meta if sound quality matters more than the price. Buy the JBL XPL-90 if the price matters more than sound quality.
If sound quality matters at all to you, skip the JBL XPL-90. It ranks near the bottom of the 131 bookshelf speakers, so look higher up the list instead.
