Audio First Cadentia 3 vs AsciLab F6Bs

Last updated: October 12, 2026

Short answer: the Audio First Cadentia 3. It ranks #7 of 216 bookshelf speakers by sound quality (rated 4.7/5); the AsciLab F6Bs ranks #20 (rated 4.5/5).

Audio First Cadentia 3 vs AsciLab F6Bs

The Audio First Cadentia 3 is the more accurate, deeper-bass pick. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 5.24 for the AsciLab F6Bs. Its bass reaches about 43Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. The catch: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).

Why pick the AsciLab F6Bs: 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. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.

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.

Listening window: the sound arriving straight at you, averaged over a small window around the listening position.

Audio First Cadentia 3 ranking card

Pros: Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 86.4dB.

Cons: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

AsciLab F6Bs ranking card

Same family: the AsciLab F6B (smaller bookshelf, ranked higher, rated 4.6/5).

Pros: 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. 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 AsciLab F6B, and listening window smoothness measures only a moderate 0.39. The 4 ohm nominal impedance calls for a reasonably capable amplifier.
