Short answer: the Polk Audio XT60, if you are buying new. The JBL HDI-3800 ranks higher than it (#26 vs #177 of 226 floorstanding speakers, 4.5/5 vs 3.5/5) but is discontinued, so only consider it used; the Polk Audio XT60 is still sold new at $370.
The JBL HDI-3800 is the better-sounding, deeper-bass option. 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Its bass reaches about 37Hz before falling 3dB, against 43.9Hz for the Polk Audio XT60. Watch for: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis.
Why pick 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 tradeoff: 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.
Buy the Polk Audio XT60, since the JBL HDI-3800 is discontinued and only worth hunting down used.

JBL HDI-3800: $5,000 per pair Discontinued eBay
Same family: the JBL HDI-1600 (bookshelf, rated 4.2/5), the JBL HDI-3600 (smaller floorstanding, ranked lower, rated 4.3/5), the JBL HDI-4500 (center, rated 3.7/5) and the JBL HDI-1200P (subwoofer, rated 3.9/5).
Pros: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Measured bass extension of 37Hz (-3dB), with a measured sensitivity of 92dB.
Cons: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate. Discontinued.

Polk Audio XT60: $370 per pair Amazon B&H Photo Video Crutchfield eBay
Same family: the Polk Audio XT15 (smaller bookshelf, rated 3.7/5), the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT70 (larger floorstanding, ranked higher, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5), the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5) and the Polk Audio Monitor XT12 (larger subwoofer, estimated 3.3/5).
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. Measured bass extension of 43.9Hz (-3dB).
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 response is also relatively uneven, with narrow-band deviation of about 0.51dB. 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.
