Short answer: the Ascend Acoustics ELX Ribbon Tower on measured sound quality, the Polk Audio XT60 on price. The Ascend Acoustics ELX Ribbon Tower ranks #6 of 71 floorstanding speakers at $5698. The Polk Audio XT60 ranks #43 at $209, $5489 cheaper.
What the Polk Audio XT60 offers: 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. Watch for: 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.
What the Ascend Acoustics ELX Ribbon Tower offers: A RAAL 70-20xram ribbon tweeter and dual SEAS Excel aluminum woofers in a 3-way, 4-driver bamboo tower measure a genuine 38.7Hz extension point with a nearly flat on axis slope of 0.05dB per octave, among the best measured towers in this batch. The bass alignment Q of 0.62 keeps the low end well damped rather than peaky. Backed by a 7 year parts and labor warranty and hand assembled in Orange County, California, with each pair matched within +/-1.5dB. Watch for: Listening window smoothness measures a moderate 0.40 and on axis deviation runs 0.286dB average, both trailing the tighter figures posted by some of the passive AsciLab and Ascend bookshelf models in this same batch. At $5,698/pair it is Ascend’s most expensive tower, well above the Titan dome tweeter version of the same cabinet. The manufacturer’s own claimed sensitivity (87.5dB) runs nearly 1.5dB higher than the independently measured average (86.1dB), worth accounting for when matching an amplifier.
