Brand: Polk

#36 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.

How it compares: Just above it: Klipsch Forte IV - $5271 more, 7.8Hz higher bass extension (-3dB). Just below it: Klipsch Heresy IV - $2969 more, 8.5Hz higher bass extension (-3dB).
