Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Perlisten A3m ranks #51 (rated 4.2/5).
The AsciLab F6Bs is the more accurate choice. A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. Its measured preference score, a predictor of how neutral it sounds, is 5.24 against 4.30 for the Perlisten A3m. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The case for the Perlisten A3m: A sealed high output monitor with dual 8 inch woofers and a waveguide tweeter, a great match for a subwoofer in a home theater. Watch for: The low-quality vendor Spinorama data measures only 85.8Hz at -3dB, 74.1Hz at -6dB, and 55.7Hz at -12dB, conflicting with Perlisten’s much deeper in-room extension claim.
