Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the Perlisten A3m ranks #52 (rated 4.2/5).
The AsciLab F6Bs is the more accurate choice. A slimmer, sealed, VESA 100 wall mountable variant of the AsciLab F6B, trading the AsciLab F6B’s passive radiator for a shallower 15.4cm deep cabinet that can go straight on a wall bracket. 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: Manufacturer data shows a narrow 1.8dB reference band, 0.305dB on-axis average absolute deviation, 0.457 listening-window smoothness, and a rated 111.4dB peak at 1m. 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.
Buy the AsciLab F6Bs. It is rated higher for sound quality than the Perlisten A3m.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
