Short answer: the Ascend Acoustics CMT-340 SE2. It ranks #24 of 222 bookshelf speakers by sound quality, rated 4.4/5, at $798. The SVS Prime Bookshelf ranks #150, rated 3.5/5, at $599, $199 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Ascend Acoustics CMT-340 SE2 is the better-sounding pick. A dual woofer bookshelf speaker with accurate sound, high sensitivity, and lots of clean output, a superb partner for a subwoofer at a modest price. The catch: Bass rolls off early for the cabinet size, measuring 77.6Hz at -3dB, 64.5Hz at -6dB, and 48.3Hz at -12dB; the preference score without a subwoofer is only 5.33.
Why pick the SVS Prime Bookshelf: Affordable bookshelf speakers with a sealed woofer compartment, wide even dispersion and reasonable sensitivity. The catch: 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.
Buy the Ascend Acoustics CMT-340 SE2. It is rated higher for sound quality, and the $199 you would save on the SVS Prime Bookshelf does not close the gap.
