#34 SVS Ultra Bookshelf: $1,200 Amazon

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.

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.

How it compares: Just above it: HiVi Swans 3.1A Sehlin Sound Solutions mod - $853 cheaper, 1.3Hz lower bass extension (-3dB). Just below it: Buchardt S400 MKII - $1200 more, 3.1Hz lower bass extension (-3dB).
