Short answer: the Radiant Acoustics Clarity 66 for better sound quality, the Polk T50 for the lower price. The Radiant Acoustics Clarity 66 ranks #11 of 228 floorstanding speakers, rated 4.6/5, at $7,998. The Polk T50 ranks #152, rated 3.8/5, at $498, $7,500 cheaper.
The Radiant Acoustics Clarity 66 is the more accurate, deeper-bass choice. Highly accurate floorstanding speakers with Purifi woofers and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 4.14 for the Polk T50. Its bass reaches about 32.2Hz before falling 3dB, against 47Hz for the Polk T50. Watch for: Vertical directivity is narrow and horizontal coverage is uneven, so listening height and placement affect tonal balance.
What the Polk T50 does well: A budget tower with twin woofers and passive radiators that gives pretty deep bass for very little money. The catch: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
