#20 AsciLab F6Bs: €799 per pair Audiophonics eBay

Pros: 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. Off axis sound tracks the on axis response unusually consistently for a sealed 2-way this size, and on axis deviation measures a clean 0.25dB average. Measured bass extension of 82.0Hz (-3dB), with a measured sensitivity of 85.2dB.

Cons: 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.

How it compares: Just above it: Epos ES14N - 1.8Hz higher bass extension (-3dB). Just below it: Perlisten R4b - 0.6Hz lower bass extension (-3dB).
