Brand: B&O
#3 B&O Beolab20: $15000 Discontinued Bang-olufsen
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.
How it compares: Just above it: Buchardt A700 - $8400 cheaper, 40W less output power.
