#150 Definitive Technology BP-9020: $500 per pair Discontinued eBay

Pros: A tower with a built in powered 8 inch subwoofer for deep bass and a wide, enveloping soundstage without a separate sub. Integrated powered 8” side-firing subwoofer with a 150-watt Class D amplifier provides exceptional sub-bass extension down to an F3 of 35Hz and F10 of 29Hz without requiring a standalone subwoofer enclosure. Forward-Focused Bipolar Array technology (dual 3.5” front midrange drivers + 1” annealed aluminum dome tweeter, plus a 3.5” rear-firing midrange driver) creates a remarkably wide, spacious soundstage with broad room envelopment. On-axis frequency response stays smooth and relatively neutral when listened to directly aligned with the tweeter. Measured average sensitivity of 87.7dB SPL (2.83V/1m) allows comfortable drive from standard multi-channel receivers. Measured bass extension of 35Hz (-3dB), with a measured sensitivity of 87.7dB.

Cons: Significant high-frequency boost creates notable treble brightness and noticeable sibilance on vocal s-sounds. Bipolar rear driver radiation creates a diffuse soundstage that compromises razor-sharp imaging focus and pinpoint instrument placement. DSP-based internal limiter aggressively compresses output below 80Hz at higher listening levels, causing lower mid-bass and sub-bass impact to diminish as volume increases. Midrange clarity shows slight ‘cuppiness’ and upper-frequency directivity irregularities due to front/rear driver interaction. Discontinued.
