Buchardt A700 vs B&O Beolab20

Last updated: August 15, 2026

Short answer: the Buchardt A700. It ranks #2 of 3 powered floorstanding speakers by sound quality at $6600; the B&O Beolab20 ranks #3 and costs $15000, so there is not much of a tradeoff to weigh.

What the Buchardt A700 offers: Excellent bass extension for a cardioid-capable design, measuring F3 51Hz/F10 22Hz, with very low multitone distortion through the midrange - among the best the reviewer has measured. Watch for: Horizontal radiation is narrower than the reviewer’s preferred ~60 degrees - closer to ±50°, giving somewhat less room involvement than he’d like.

What the B&O Beolab20 offers: CEA2034 spinorama shows a nearly flat response down to 20Hz, unusual for this cabinet size. Watch for: Overpriced and not recommended. 5dB dip at 7khz.

Buy the Buchardt A700. It ranks higher for sound quality than the B&O Beolab20 and costs less, so there is no real case for the other one.

Buchardt A700: $6,600 Buchardt Audio

Buchardt A700 ranking card

Pros: Excellent bass extension for a cardioid-capable design, measuring F3 51Hz/F10 22Hz, with very low multitone distortion through the midrange - among the best the reviewer has measured. Selectable Master Tuning DSP profiles let you switch the speaker’s entire voicing via USB, including a cardioid bass mode that made the low end noticeably more neutral in the reviewer’s room versus the standard tuning. All-in-one powered design with 4x150W amplification per speaker (front/rear 6” woofers, 6” midwoofer, 3/4” waveguide-loaded tweeter), so no separate amp is needed. The optional Platin wireless hub adds streaming plus room EQ and manual parametric adjustment from a phone app - the reviewer strongly recommends buying it. Checks off nearly every audiophile box: great out-of-box sound, extensive tuning flexibility, and a 45-day home trial policy.

Cons: Horizontal radiation is narrower than the reviewer’s preferred ~60 degrees - closer to ±50°, giving somewhat less room involvement than he’d like. Vertical dispersion is quite narrow (about ±10°), meaning seated ear height needs to be dialed in carefully; not well suited to multi-row home theater seating. Compression starts to show at 102dB output, though it’s not severe. Genuinely expensive at roughly $6,600/pair (€6,000), and the optional Platin hub - which the reviewer considers close to essential for the best experience - adds another ~€300 on top.

B&O Beolab20: $15000 Discontinued Bang-olufsen

B&O Beolab20 ranking card

Pros: CEA2034 spinorama shows a nearly flat response down to 20Hz, unusual for this cabinet size. Predicted in-room response looks even better than the on-axis curve, with a good downward slope. Distortion at 86dB SPL/1m is pretty good for the size.

Cons: Overpriced and not recommended. 5dB dip at 7khz. Messy vertical directivity - the reviewer recommends staying right at the tweeter axis. Distortion at 700hz. Resonance at 5khz. At 96dB SPL/1m, harmonics of an 800Hz resonance become more audible, with broad distortion elevation through the midrange. Discontinued.
