Short answer: the ELAC Uni-Fi Reference UBR62. It ranks #54 of 131 bookshelf speakers by sound quality, rated 4.1/5, at $1,199; the SVS Ultra Bookshelf ranks #62, rated 3.9/5, and costs $1,200, so there is little reason to consider the other one.
Why pick the ELAC Uni-Fi Reference UBR62: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Watch for: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed.
What the SVS Ultra Bookshelf does well: Noticeably more tonally neutral than the cheaper SVS Prime Bookshelf, with response staying within about -3dB/+1.5dB on average: a genuine step up in linearity for roughly double the price. The catch: Still has a boosted upper mid-range/mid-range area, though less severe than the Prime: the reviewer suspects a baffle-step or tweeter-level issue rather than a resonance, giving mixes a slightly forward, occasionally tinny character.
One note: the SVS Ultra Bookshelf is no longer sold new, but at #62 of 131 bookshelf speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the ELAC Uni-Fi Reference UBR62. It is rated higher for sound quality than the SVS Ultra Bookshelf and costs less, so only choose the other one for a particular feature it does better.

ELAC Uni-Fi Reference UBR62: $1,199 per pair Amazon eBay
Pros: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Erin found the directivity and overall tonality well controlled, with dual front slot vents minimizing placement sensitivity and cabinet bracing suppressing obvious coloration. The mostly 5-ohm-or-higher load is manageable for a genuinely 4-ohm-capable amplifier, and the coherent concentric upper range supports stable imaging across seats. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed. Impedance reaches 4 ohms near 50Hz (Erin), while woofer excursion and bass output were less capable than expected for the cabinet size. A broad 500-700Hz rise and associated lower/female-vocal coloration were audible, and the slightly subdued listening-window treble is necessary to avoid an overly bright in-room balance rather than evidence of ruler-flat axial tuning.

SVS Ultra Bookshelf: $1,200 per pair Discontinued eBay
Newer model: the SVS Ultra Evolution Bookshelf. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: Noticeably more tonally neutral than the cheaper SVS Prime Bookshelf, with response staying within about -3dB/+1.5dB on average: a genuine step up in linearity for roughly double the price. Slightly higher sensitivity than the Prime (about 87.8dB) with similarly wide, consistent horizontal radiation. Toeing the speakers out about 30 degrees smooths the in-room response nicely if the on-axis tonal balance runs a bit forward for your taste. Distortion and dynamics hold up well; this is a mature, well-regarded design (roughly a decade old at review time) that’s aged better than many contemporaries. Measured bass extension of 69Hz (-3dB), with a measured sensitivity of 87.8dB.
Cons: Still has a boosted upper mid-range/mid-range area, though less severe than the Prime: the reviewer suspects a baffle-step or tweeter-level issue rather than a resonance, giving mixes a slightly forward, occasionally tinny character. Bass extension is modest for the price (F3 69Hz, F10 48Hz measured): SVS is clearly counting on you pairing this with one of their subwoofers rather than expecting full-range performance from the bookshelf alone. Measured minimum impedance dips to about 3.8 ohms, so a 4-ohm-stable amplifier is recommended rather than a basic 8-ohm-only AVR. Radiation pattern is wide (around 80°), wider than the reviewer’s typical ~60° sweet spot preference, so acoustic treatment on nearby walls helps tame reflections and keep the off-axis response from diverging too much from on-axis. Discontinued; SVS replaced the Ultra line with the Ultra Evolution series.
