Short answer: the Klipsch RP-8000F II for dynamics, the Polk Audio XT60 for bass extension. The RP-8000F II is the most sensitive of its RP II floorstander line at about 92dB measured and the cleanest under load, but its mid-bass sounds lean despite dual 8-inch woofers and its bass never reached the expected 50Hz in-room. The XT60 gets to 43.9Hz at -3dB and 38.1Hz at -10dB, though its loose low end is the trade.
Buy the Polk Audio XT60 if the price matters more than sound quality. Buy the Klipsch RP-8000F II if sound quality matters more than the price.

Polk Audio XT60: $458 per pair Amazon B&H Photo Video Crutchfield eBay
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.

Klipsch RP-8000F II: $1,159.98 per pair Amazon eBay
Pros: Highest sensitivity of the RP II floorstander line (~92dB measured) and the best dynamics/compression behavior of the three under load: the cleanest at high output. Dual 8-inch woofers and the highest power handling in the line. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 92dB.
Cons: Mid-bass sounds lean despite the dual 8-inch woofers, and bass extension disappointed for its size: expected to reach 50Hz, didn’t get there in-room. Has its own edgy upper-mid bump (2-6kHz) that’s harder to EQ out than the other two models’ issues, since it stems from the vertical horn/woofer offset rather than simple tonal balance. The most placement-critical of the three, with the narrowest horizontal (~40-50 degrees) and vertical (+5/-10 degrees) dispersion.
