Short answer: the SVS Prime Bookshelf. It ranks #63 of 100 bookshelf speakers by sound quality at $699; the KEF Q3 Meta ranks #64 and costs $899.99, so there is not much of a tradeoff to weigh.
On the SVS Prime Bookshelf side: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Set against that: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range.
The case for 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) -. 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.
Buy the SVS Prime Bookshelf. It ranks higher for sound quality than the KEF Q3 Meta and costs less, so there is no real case for the other one.

SVS Prime Bookshelf: $699.00 Amazon
Pros: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Overall response stays within about ±3dB from 80Hz-16kHz, which the reviewer calls reasonable for the price point. Wide, consistent horizontal radiation. Toeing the speakers 30 degrees off-axis smooths the in-room response noticeably if the on-axis tonal balance isn’t to your taste.
Cons: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range. Measured minimum impedance dips below 4 ohms (EPDR even lower), so an 8-ohm-only amplifier or AVR may struggle - a 4-ohm-stable amp or separate amplification is recommended. Bass extension is modest (F3 72Hz, F10 49Hz measured) - SVS clearly designed this to be paired with one of their subwoofers rather than to stand fully alone. Compared directly against its pricier sibling, the SVS Ultra Bookshelf, in the same review, the reviewer found the Ultra noticeably more tonally neutral.

KEF Q3 Meta: $899.99 Amazon Crutchfield
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.
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.
