Short answer: the Polk T50, if you are buying new. The Definitive Technology BP-9020 measures as well as it (#124 vs #126 of 188 floorstanding speakers, 3.8/5 vs 3.8/5) but is discontinued, so only consider it used; the Polk T50 is still sold new at $374.
The case for the Polk T50: Pretty deep bass for the price. Watch for: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
The Definitive Technology BP-9020 is the more accurate, deeper-bass pick. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.08 against 4.14 for the Polk T50. Its bass reaches about 35Hz before falling 3dB, against 47Hz for the Polk T50. The tradeoff: Significant high-frequency boost creates notable treble brightness and noticeable sibilance on vocal s-sounds.
Buy the Polk T50, since the Definitive Technology BP-9020 is discontinued and only worth hunting down used.

Same family: the Polk T15 (bookshelf, rated 1.9/5).
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.

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