Short answer: the Audio First Cadentia 3. It ranks #7 of 222 bookshelf speakers by sound quality (rated 4.7/5); the AsciLab F6Bs ranks #20 (rated 4.5/5).
The Audio First Cadentia 3 is the more accurate, deeper-bass pick. A large three way bookshelf speaker with near textbook accuracy, a big enveloping soundstage, and deep, punchy bass that stays clean when loud. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 5.24 for the AsciLab F6Bs. Its bass reaches about 43Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The catch: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
Why pick the AsciLab F6Bs: A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
