Klipsch Forte IV vs Polk T50

Last updated: October 31, 2026

Short answer: the Polk T50 for cheap deep bass, the Klipsch Forte IV for a heritage three-way. The T50 gives pretty deep bass for the price, but our notes flag a 5dB peak at 1kHz and a 4dB bright top end from 11kHz on up. The Forte IV pairs a 12” woofer with a 1” titanium tweeter and 1.75” compression driver midrange, and contrary to Klipsch’s classic reputation it is not forward or bright. $5,499.98 against $498.
