Short answer: the KEF Q Concerto Meta for measured neutrality, the SVS Prime Bookshelf for price. Erin’s Audio Corner measurements rank the Q Concerto Meta #11 of 131 large bookshelf speakers at $1,399.99, well ahead of the Prime Bookshelf at #87 for $699, $700.99 less.
The Q Concerto Meta’s three-way design measures deeper and holds its tonal balance together far better. Its 6.5-inch hybrid aluminum woofer, 4-inch aluminum midrange, and MAT-equipped tweeter extend to 35Hz at -10dB, well past the Prime Bookshelf’s 49Hz. Erin’s Audio Corner praises really good in-room neutrality with consistent horizontal directivity from seat to seat, directivity that holds remarkably steady from lower treble into upper treble where many similarly priced speakers narrow sharply. The tradeoff is a radiation pattern of about ±50 degrees, narrower than the reviewer’s preferred ±60 degrees for a stronger sense of envelopment, and it needs to sit closer to on-axis since heavy toe-out combined with its shelved-down top end can make it sound noticeably dark.
The Prime Bookshelf’s tonal balance is the bigger compromise, and it’s clearly meant to be paired with a subwoofer. Its 6.5-inch woofer sits in its own sealed sub-compartment inside the cabinet for cleaner midrange and bass separation, and it manages reasonable sensitivity for the price at about 87dB, with wide, consistent horizontal radiation. But Erin’s Audio Corner describes a scooped midrange paired with a boosted upper midrange that creates an audibly uneven tonal balance, plus an additional dip in the treble around 4kHz to 5kHz that reads as slightly tinny. Its measured minimum impedance dips below 4 ohms, so an 8-ohm-only amplifier or AVR may struggle, and a 4-ohm-stable amp is recommended. In a direct comparison against its own pricier sibling, the SVS Ultra Bookshelf, the reviewer found the Ultra noticeably more tonally neutral.
Buy the KEF Q Concerto Meta for a much more even, deeper-reaching measured performance, and keep it close to on-axis rather than heavily toed out.
Buy the SVS Prime Bookshelf if the lower price matters more than tonal accuracy, and plan on pairing it with a subwoofer and a 4-ohm-capable amplifier.

KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises: one of the reviewer’s top 10 picks under $1,500. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out: combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

SVS Prime Bookshelf: $699.00 per pair Amazon eBay
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. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 87dB.
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.
