Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Sonus Faber Lumina II Amator ranks #188 (rated 3.0/5).
The AsciLab F6Bs is the better-sounding option. 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 Sonus Faber Lumina II Amator is the deeper-bass pick. A luxurious Italian bookshelf speaker with a gorgeous cabinet, solid bass for its size and wide, consistent dispersion. Its bass reaches about 63Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The catch: Very bright treble, running 3-6dB above the midrange depending on measurement angle: independently corroborated by other owners online, not just one reviewer’s opinion.
Buy the AsciLab F6Bs. It is rated higher for sound quality than the Sonus Faber Lumina II Amator.
