Short answer: the SVS Ultra Evolution Bookshelf is the newer model that replaces the SVS Ultra Bookshelf, but only the SVS Ultra Bookshelf has been measured and ranked so far, so this comparison is on specs and features rather than sound. The SVS Ultra Bookshelf is discontinued, so it is now a used buy.
What the SVS Ultra Evolution Bookshelf offers: Two-way rear-ported standmount with a 6.5” composite glass fiber woofer and a 1” diamond-coated aluminium dome tweeter in a time-aligned cabinet.
What the SVS Ultra Bookshelf brings: 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.
On paper: The SVS Ultra Evolution Bookshelf is rated down to 40Hz against 45Hz, though makers quote these at different tolerances.
Buy the SVS Ultra Bookshelf if you want a speaker whose sound quality has been measured and ranked.
Buy the SVS Ultra Evolution Bookshelf if you want the newer model, with deeper rated bass, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
SVS Ultra Evolution Bookshelf: $1,199.98 per pair SVS eBay
Older model: the SVS Ultra Bookshelf (rated 3.9/5).
Pros: Two-way rear-ported standmount with a 6.5” composite glass fiber woofer and a 1” diamond-coated aluminium dome tweeter in a time-aligned cabinet. SVS rates it at 40Hz to 40kHz (±3dB), deep bass extension for a bookshelf, with 87dB sensitivity and a 6 ohm nominal load.
Cons: Measured by Stereophile and Audioholics, but not in the Spinorama format used for this ranking, so its tonal balance and directivity can’t yet be compared directly with ranked speakers. A rear port needs some space from the wall.

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.
