Short answer: the Polk Audio XT70. It ranks #170 of 228 floorstanding speakers by sound quality, rated 3.6/5, at $698. The Polk Audio XT60 ranks #178, rated 3.5/5, at $458, $240 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Polk Audio XT70: A budget tower with twin woofers and two passive radiators for extra bass, working with 4 or 8 ohm amplifiers. The catch: On-axis smoothness (0.274) and listening-window smoothness (0.303) are unremarkable for a tower this size, with a pronounced +0.28dB per octave upward tonal tilt giving it a brighter-leaning balance and a predicted in-room smoothness of just 0.31.
Why pick the Polk Audio XT60: A budget tower with a woofer and two passive radiators that gives surprisingly deep bass for the price. Watch for: Bass alignment Q (lfq 0.96) is an unusually high, underdamped figure for a tower speaker, consistent with owner reports of a slightly loose, boomy low end at higher volumes.
Buy the Polk Audio XT70. It is rated higher for sound quality, and the $240 you would save on the Polk Audio XT60 does not close the gap.
