Short answer: the Ascend CBM-170 SE2. It ranks #66 of 130 bookshelf speakers by sound quality at $468; the KEF Q3 Meta ranks #89 and costs $899.99, so there is not much of a tradeoff to weigh.
What the KEF Q3 Meta offers: 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. Watch for: 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.
What the Ascend CBM-170 SE2 offers: On-axis response is impressively flat from about 100Hz to 2kHz, staying within roughly ±1dB, with a clean, gradual bass rolloff below that. The directivity index rises smoothly and predictably through the crossover region, and the estimated in-room response shows a smooth, consistent downward tilt from 100Hz to 10kHz with no major discontinuities - close to the ideal in-room target shape. Measured sensitivity of 86.8dB nearly matches Ascend’s 87dB spec. The manufacturer’s own preference-score modeling comes out to 5.81 unequalized (rising to 8.17 with an ideal subwoofer, or 6.33/8.41 with EQ applied) - a strong result for a compact 2-way, and a clear step up from the original CBM-170 SE this replaces. Watch for: A narrow dip in the on-axis and listening-window response appears in the 3-5kHz range (down to about -2.7dB), mirrored by a matching dip in the directivity index at the same frequencies - likely a brief widening of dispersion right at the tweeter/woofer crossover. High-frequency directivity narrows substantially above 10kHz, typical for a small dome tweeter, so the top octave will sound more reserved off-axis than on-axis. Bass rolls off as expected for a compact 2-way monitor: -3dB around 70Hz and -10dB around 50Hz, so a subwoofer is needed for full-range use. This data comes from the manufacturer’s own Klippel measurements rather than an independent third-party review, so there’s no outside verification of channel matching, distortion, or unit-to-unit consistency.
Buy the Ascend CBM-170 SE2. It ranks higher for sound quality than the KEF Q3 Meta and costs less, which settles it without a real tradeoff to make.
