Adding a subwoofer should make a system sound bigger, deeper and more immersive. It shouldn't introduce hum, noise or another round of second-guessing.
Performance Subwoofer is designed to make the connection between your amplifier and active subwoofer simple, reliable and engineered for musical accuracy.
Built around QED's proven Solid Complementary Conductor™ Technology, it helps preserve signal timing and integrity while advanced shielding technology protects delicate low-frequency signals from the electrical noise found in modern homes.
Whether you're adding a subwoofer to a stereo system, expanding a home cinema setup or finally giving your speakers the low-frequency support they deserve, Performance Subwoofer gives you the confidence that this vital connection is properly taken care of.
