Short answer: it depends on whether you can put the tweeter at ear level. The JBL XPL-90 is nearly ruler-flat on-axis to 1kHz with even horizontal directivity until it beams above 10kHz, but crossover peaking around 3kHz, treble peaking above 10kHz and poor vertical directivity color it. The KEF Q3 Meta offers unusually wide dispersion, about +/-60 degrees each way, but strains in the 1-2kHz region above about 90dB at 10 feet.
Buy the KEF Q3 Meta. It is rated higher for sound quality, and the JBL XPL-90 is discontinued, so it is only available used.

KEF Q3 Meta: $899.99 per pair Amazon Crutchfield eBay
Older model: the KEF Q350 (ranked lower, rated 3/5).
Pros: Coaxial two-way design (1” vented aluminum dome tweeter with Meta absorber embedded in a 6.5” aluminum cone mid/bass driver) delivering unusually wide dispersion both horizontally and vertically (about ±60° each): wider than typical KEF models, which usually run closer to ±50° horizontal and ±15-20° vertical for non-coaxial designs. A deliberate ~2dB bump around 120Hz gives a satisfying sense of kick-drum impact, a voicing choice the reviewer personally favors even though it’s not strictly accurate. Extended bass-shelf tuning allows placement close to a rear wall (about 1 foot) without sounding boomy. Good directivity overall means it takes well to EQ correction if desired. Cabinet resonances around 350-370Hz and 600Hz look concerning in impedance measurements, but blind ABX testing (24 trials) after adding damping material couldn’t reliably distinguish the treated cabinet from the untreated one: these particular resonances appear to fall below the threshold of audibility. Sturdier build than previous KEF Q-series models. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 84.5dB.
Cons: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application. A slight loss of attack and clarity around 1-2kHz was noticeable both subjectively and in measurements. F3 of 52Hz with a fairly quick rolloff below 50Hz means a subwoofer is still recommended for real bass extension, even for moderate-volume home theater use. Sealed configuration (using the included port bungs) pushes the bass rolloff up into the 100Hz+ region: the reviewer recommends leaving it in ported mode instead. Sounds best pointed directly at the listener; toeing it out 30° rolls off the top end without a meaningful soundstage benefit. Compression testing shows real breakdown at 102dB/1m, with the woofer losing excursion control: confirms the practical output ceiling. An unexplained -5dB dip appears in on-axis measurements that the reviewer couldn’t attribute to a specific cause.

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.
