Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Arendal 1528 Monitor 8 ranks #23 (rated 4.4/5).
What the AsciLab F6Bs does well: 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.
The Arendal 1528 Monitor 8 is the deeper-bass choice. A big three way monitor with dual 8 inch woofers, bass deep enough to skip a subwoofer, and extremely low distortion at high volume. Its bass reaches about 41Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The catch: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.
