Short answer: the Dynaudio Heritage Special on measured sound quality, the SVS Prime Bookshelf on price. The Dynaudio Heritage Special ranks #29 of 222 bookshelf speakers, rated 4.4/5, at $7,000. The SVS Prime Bookshelf ranks #150, rated 3.5/5, at $599, $6,401 cheaper.
The SVS Prime Bookshelf is the more accurate pick. Affordable bookshelf speakers with a sealed woofer compartment, wide even dispersion and reasonable sensitivity. Its measured preference score, a predictor of how neutral it sounds, is 5.17 against 4.32 for the Dynaudio Heritage Special. 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.
The Dynaudio Heritage Special is the better-sounding, deeper-bass choice. A limited edition bookshelf speaker with huge output for its size, robust bass, and a big, well proportioned soundstage. Its bass reaches about 52Hz before falling 3dB, against 72Hz for the SVS Prime Bookshelf. The tradeoff: At lower listening volumes, dynamic range and kick-drum punch fell short of higher-sensitivity speakers the reviewer has tested (JBL 4367, KEF Reference 1 Meta): the sheer output ceiling is impressive, but it isn’t a highly dynamic-sounding speaker at modest levels.
Buy the SVS Prime Bookshelf when the price outweighs sound quality for you, and the Dynaudio Heritage Special when sound quality outweighs the price instead.
