Short answer: the Klipsch RP-8000F II, because the Polk’s peaks are harder to overlook. The T50 does deliver pretty deep bass for the price, but a 5dB peak at 1kHz and a 4dB bright top end from 11kHz on up color the midrange and treble. The Klipsch costs $1,159.98 against $498 and counters with ~92dB measured sensitivity and better dynamics, though its mid-bass is lean and bass did not reach the expected 50Hz.
Buy the Klipsch RP-8000F II if sound quality matters more than the price. Buy the Polk T50 if the price matters more than sound quality.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
