Short answer: the Ascend Acoustics Sierra-2EX V2. It ranks #41 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $1,748. The SVS Prime Bookshelf ranks #150, rated 3.5/5, at $599, $1,149 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Ascend Acoustics Sierra-2EX V2 is the more accurate, deeper-bass choice. A ribbon tweeter bookshelf speaker with hand matched pairs, a frequency response printout for each unit, and a long seven year warranty. Its measured preference score, a predictor of how neutral it sounds, is 5.88 against 5.17 for the SVS Prime Bookshelf. Its bass reaches about 58.6Hz before falling 3dB, against 72Hz for the SVS Prime Bookshelf. The catch: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers.
What the SVS Prime Bookshelf does well: Affordable bookshelf speakers with a sealed woofer compartment, wide even dispersion and reasonable sensitivity. The tradeoff: 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 Sierra-2EX V2. It is rated higher for sound quality, and saving $1,149 with the SVS Prime Bookshelf does not make up for the sound-quality gap.
