Short answer: the Definitive Technology BP-9020 for better sound quality, the Polk Audio XT60 for the lower price. The Definitive Technology BP-9020 ranks #33 of 59 floorstanding speakers at $500. The Polk Audio XT60 ranks #36 at $229, $271 cheaper.
On the Definitive Technology BP-9020 side: 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. The tradeoff: Significant high-frequency boost creates notable treble brightness and noticeable sibilance on vocal s-sounds.
The case for the Polk Audio XT60: Passive-radiator-loaded design (6.5” woofer plus two 6.5” passive radiators) gives deeper bass than the driver size alone would suggest - 43.9Hz at -3dB / 38.1Hz at -10dB, genuinely competitive extension for a budget tower. The catch: Bass alignment Q is the highest, least-controlled figure in this entire batch, consistent with owner reports of a slightly loose, boomy low end at higher volumes.
Buy the Definitive Technology BP-9020 if sound quality matters more than the price. Buy the Polk Audio XT60 if the price matters more than sound quality.

Definitive Technology BP-9020: $500.00 Discontinued
Pros: 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.
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.

Polk Audio XT60: $229 Amazon Bhphotovideo Crutchfield
Pros: Passive-radiator-loaded design (6.5” woofer plus two 6.5” passive radiators) gives deeper bass than the driver size alone would suggest - 43.9Hz at -3dB / 38.1Hz at -10dB, genuinely competitive extension for a budget tower. Hi-Res Audio certified, Dolby Atmos/DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs.
Cons: Bass alignment Q (lfq 0.96) is the highest, least-controlled figure in this entire batch, consistent with owner reports of a slightly loose, boomy low end at higher volumes. On-axis deviation (nbd_on_axis 0.512) is also the roughest measured figure in the batch. The vinyl-wrapped (not wood veneer) cabinet reads as budget up close per owner reviews, and at least one owner reported blowing a driver under sustained heavy bass - some caution is warranted with bass-heavy source material at volume.
