Short answer: the KEF Q Concerto Meta. It ranks #11 of 203 bookshelf speakers by sound quality (rated 4.6/5) at $1,399.99 and is still sold new; the JBL XPL-90 ranks #166 (rated 3.1/5) and is discontinued, so it is only an option used.
The KEF Q Concerto Meta is the more accurate, deeper-bass pick. Really good in-room neutrality with consistent horizontal directivity from seat to seat. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 3.70 for the JBL XPL-90. Its bass reaches about 53Hz before falling 3dB, against 77.6Hz for the JBL XPL-90. The catch: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the JBL XPL-90 does well: Nearly ruler-flat on-axis response up to 1kHz with even horizontal directivity until the tweeter beams above 10kHz. 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.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality and still sold new, while the JBL XPL-90 is discontinued.

The Two Speakers In Full
KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Same family: the KEF Q1 Meta (smaller bookshelf, rated 3.6/5), the KEF Q4 Meta (smaller bookshelf, estimated 3.4/5), the KEF Q3 Meta (smaller bookshelf, ranked lower, rated 3.4/5), the KEF Q7 Meta (smaller floorstanding, estimated 3.5/5), the KEF Q11 Meta (larger floorstanding, rated 4/5) and the KEF Q6 Meta (center, rated 3.9/5).
Pros: 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. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: 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.

JBL XPL-90: $1,298 per pair used (vintage, late 1980s) Discontinued eBay
Pros: 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. Measured bass extension of 77.6Hz (-3dB), with a measured sensitivity of 85dB.
Cons: 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.
