Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Philharmonic BMR Monitor ranks #134 (rated 3.6/5).
The AsciLab F6Bs is the better-sounding pick. A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. The catch: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The Philharmonic BMR Monitor is the more accurate, deeper-bass option. Three-way bookshelf speakers with premium drivers, a well-built cabinet and extremely wide dispersion for a broad soundstage. Its measured preference score, a predictor of how neutral it sounds, is 6.02 against 5.24 for the AsciLab F6Bs. Its bass reaches about 47Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The tradeoff: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks.
Buy the AsciLab F6Bs. It is rated higher for sound quality than the Philharmonic BMR Monitor.
