Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5) and is still sold new; the Philharmonic BMR (v1) ranks #40 (rated 4.3/5) and is discontinued, so it is only an option used. The Philharmonic BMR (v1)’s replacement, the Philharmonic BMR Monitor, is rated 3.6/5 at $2,200.
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. The tradeoff: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The Philharmonic BMR (v1) is the deeper-bass pick. A large three way bookshelf speaker with a ribbon tweeter, flat response, broad coverage, and an unusually expansive midrange. Its bass reaches about 62Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. Watch for: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification.
Buy the AsciLab F6Bs. It is rated higher for sound quality and still sold new, while the Philharmonic BMR (v1) is discontinued.
