Short answer: the Mission LX-3 MKII. It ranks #138 of 222 bookshelf speakers by sound quality (rated 3.6/5); the SVS Prime Bookshelf ranks #150 (rated 3.5/5).
The SVS Prime Bookshelf is the more accurate choice. 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 4.17 for the Mission LX-3 MKII. 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 case for the Mission LX-3 MKII: Large affordable standmount speakers with a 6.5 inch woofer, useful bass and easy to drive sensitivity. The catch: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt.
