Short answer: the AsciLab F6Bs. It ranks #20 of 130 bookshelf speakers by sound quality at $799; the Perlisten A3m ranks #43 and costs $3000, which makes this an easy call rather than a real tradeoff.
What the AsciLab F6Bs offers: A slimmer, sealed, VESA 100 wall mountable variant of AsciLab’s F6B, trading the F6B’s passive radiator for a shallower 15.4cm deep cabinet that can go straight on a wall bracket. The sound power directivity index has the tightest standard deviation, 3.32, of anything in this batch of new additions, meaning off axis energy tracks the on axis response unusually consistently for a sealed 2-way this size, and on axis deviation measures a clean 0.25dB average. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio. Bass extension is measured at 82.0Hz at -3dB, noticeably less than the passive radiator equipped F6B, and listening window smoothness measures only a moderate 0.39. The 4 ohm nominal impedance calls for a reasonably capable amplifier.
What the Perlisten A3m offers: 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. Its preference score rises from 3.39 to 6.42 with a subwoofer. A sealed cabinet, two 8-inch carbon-fiber woofers, and a controlled tweeter waveguide make this a high-output monitor. 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. A 3.70 sound-power directivity-index standard deviation and 0.295 predicted-in-room smoothness are merely average. It is large, heavy, 4-ohm nominal, and expensive at $3,000/pair.
Buy the AsciLab F6Bs. It ranks higher for sound quality than the Perlisten A3m and costs less, which settles it without a real tradeoff to make.
