Short answer: the Focal Aria 906 for a flatter response, the SVS Prime Bookshelf on price. The Focal’s CEA2034 spinorama shows flat bass and an in-room response almost perfect prior to 1kHz, and the reviewer rates it good overall, though it has a 3dB dip around 2.8kHz. The SVS at $699 has about 87dB sensitivity and a sealed sub-compartment for its 6.5-inch woofer, but scooped mids and a 4-5kHz treble dip leave an uneven tonal balance.
Buy the SVS Prime Bookshelf. It is rated higher for sound quality, and the Focal Aria 906 is discontinued, so it is only available used.

The Two Speakers In Full
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.

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.
