Short answer: the Ascend Acoustics ELX Ribbon Tower on measured sound quality, the Polk T50 on price. The Ascend Acoustics ELX Ribbon Tower ranks #12 of 228 floorstanding speakers, rated 4.6/5, at $5,698. The Polk T50 ranks #152, rated 3.8/5, at $498, $5,200 cheaper.
Why pick the Polk T50: A budget tower with twin woofers and passive radiators that gives pretty deep bass for very little money. The tradeoff: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
The Ascend Acoustics ELX Ribbon Tower is the more accurate, deeper-bass pick. Highly accurate three way bamboo towers with a ribbon tweeter, deep tight bass and a long warranty. Its measured preference score, a predictor of how neutral it sounds, is 6.97 against 4.14 for the Polk T50. Its bass reaches about 38.7Hz before falling 3dB, against 47Hz for the Polk T50. The catch: Listening window smoothness measures a moderate 0.40 and on axis deviation runs 0.286dB average, both trailing the tighter figures posted by some smaller passive AsciLab and Ascend bookshelf models.
Buy the Polk T50 when the price outweighs sound quality for you, and the Ascend Acoustics ELX Ribbon Tower when sound quality outweighs the price instead.
