37HZ Subsonic Bass Blocker

Enhance your audio system's performance and longevity. The Harrison Labs 37 Hz Bass Blocker is a precision-engineered passive inline crossover designed to eliminate power-robbing subsonic frequencies, while featuring dual (Stereo L/R) RCA inputs and outputs integrated into a single cable assembly to process both channels simultaneously. This High-Pass Filter (HPF) protects your speakers and subwoofers from over-excursion, ensuring a cleaner, louder, and more efficient signal.
