Short answer: the Focal Aria 906 for flat bass and a near-perfect predicted in-room response below 1kHz; the KEF Q3 Meta for wider dispersion. The Focal’s spinorama shows very flat bass and the reviewer rated it “good,” with only a 3dB dip around 2.8kHz as a notable flaw. The KEF’s coaxial layout spreads wider, about +/-60 degrees each way, but compresses in the 1-2kHz region above about 90dB at 10 feet.
Buy the KEF Q3 Meta. It is rated higher for sound quality and still sold new, while the Focal Aria 906 is discontinued.

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.

Focal Aria 906: $2,199.00 per pair used Discontinued Amazon eBay
Newer model: the Focal Aria Evo X N°1. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Predicted in-room response is almost perfect prior to 1kHz. Horizontal dispersion of about ±60 degrees is good and stays even out to about -12dB before getting erratic. Woofer distortion is quite low at 86dB SPL/1m. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 3dB dip around 2.8kHz. Some resonance around 800Hz, small directivity error around 7kHz. A dip in the upper midrange also shows up in the predicted in-room response. Distortion becomes problematic at 96dB SPL/1m, with a notable peak around 1.3-1.5kHz alongside broader midrange elevation. Discontinued.
