Short answer: the Perlisten S4b. It ranks #2 of 222 bookshelf speakers by sound quality (rated 4.8/5); the Mission LX-3 MKII ranks #138 (rated 3.6/5).
The Perlisten S4b is the more accurate pick. A compact sealed bookshelf speaker with reference grade accuracy, exceptionally smooth dispersion, and very low distortion at high volume. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 4.17 for the Mission LX-3 MKII. The catch: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification.
The Mission LX-3 MKII is the deeper-bass choice. Large affordable standmount speakers with a 6.5 inch woofer, useful bass and easy to drive sensitivity. Its bass reaches about 67.4Hz before falling 3dB, against 78Hz for the Perlisten S4b. 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.
