Short answer: the AsciLab F6Bs. It ranks #20 of 203 bookshelf speakers by sound quality (rated 4.5/5); the Arendal 1528 Monitor 8 ranks #23 (rated 4.4/5).
What the AsciLab F6Bs does well: 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. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The Arendal 1528 Monitor 8 is the deeper-bass choice. Three-way design featuring a 28mm tweeter, 5” mid-range, and dual 8” mid-bass drivers in a convertible sealed/ported HDF cabinet, with a supplied port bung for sealed operation near a wall. Its bass reaches about 41Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The catch: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.

AsciLab F6Bs: €799 per pair Audiophonics eBay
Same family: the AsciLab F6B (smaller bookshelf, ranked higher, rated 4.6/5).
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.

Arendal 1528 Monitor 8: $6000 per pair Arendal Sound eBay
Same family: the Arendal Sound 1528 Bookshelf 8 (smaller bookshelf, ranked lower, estimated 4.4/5), the Arendal Sound 1528 Tower 8 (floorstanding, estimated 4.5/5) and the Arendal Sound 1528 Center 8 (center, estimated 4.1/5).
Pros: Three-way design featuring a 28mm tweeter, 5” mid-range, and dual 8” mid-bass drivers in a convertible sealed/ported HDF cabinet, with a supplied port bung for sealed operation near a wall. In ported configuration, reaches down to about 35Hz in most rooms (F3 41Hz, F10 26Hz): deep enough that many listeners could skip a subwoofer unless they want output below 40Hz. Extremely low distortion and compression across the board (harmonic, multitone, and both long- and short-term compression testing): among the best the reviewer has tested at this price, beating speakers costing twice as much. Wide, consistent horizontal soundstage of about ±60°. Smooth, non-fatiguing high frequency rather than the elevated “detail” boost common on speakers marketed for resolution. A slight forwardness around 1.5kHz adds a touch of attack without tipping into brightness. Measured bass extension of 41Hz (-3dB), with a measured sensitivity of 84.4dB.
Cons: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker. A diffraction-related flare in the upper-midrange/lower-treble (around 1.5-2kHz) gives a mild forwardness that benefits from sidewall absorption panels, though it’s not a major issue. Vertical sweet spot is fairly narrow at about ±20°: a bigger consideration for multi-row home theater seating than rivals like the MoFi SourcePoint 8, which manages about ±60°. The MoFi SourcePoint 8, a similarly-priced rival, also has more linear bass with no midbase dip, at the cost of a more elevated top end. Minor resonances appear around 400Hz and 800Hz in measurements, though the reviewer considers them inaudible or insignificant. Very heavy (about 104 lbs each) HDF cabinet requires dedicated, sturdy stands. Low EPDR (dips to about 1.9 ohms in two spots) means a Class AB amplifier needs to comfortably handle a 4-ohm load without overheating; a Class D amp is a safer choice for full-range use.
