Short answer: the KEF Q3 Meta. It ranks #89 of 131 bookshelf speakers by sound quality, rated 3.4/5, at $899.99; the JBL 4309 ranks #97, rated 3.3/5, and costs $2,200, so there is not much of a tradeoff to weigh.
Why pick the KEF Q3 Meta: 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. The tradeoff: 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.
The case for the JBL 4309: A compact front-ported JBL monitor with an HDI horn, compression driver, 6.5-inch pulp woofer and adjustable UHF level. The catch: Measured preference is modest for a roughly $2200 pair, and the four-ohm load needs solid amplification.
Buy the KEF Q3 Meta. It is rated higher for sound quality than the JBL 4309 and costs less, which makes it the one to get unless you need something the other one does better.

KEF Q3 Meta: $899.99 per pair Amazon Crutchfield eBay
Older model: the KEF Q350 (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 4309: $2,200 per pair eBay
Pros: A compact front-ported JBL monitor with an HDI horn, compression driver, 6.5-inch pulp woofer and adjustable UHF level. The local snapshot records 42Hz extension, a 3.32 raw score and 5.33 with a subwoofer. Measured bass extension of 60.1Hz (-3dB).
Cons: Measured preference is modest for a roughly $2200 pair, and the four-ohm load needs solid amplification. The horn’s controlled dispersion provides less room-filling width than some conventional dome designs.
