QED Performance Subwoofer Cable 3m

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.

About the QED QE7711

From our tech experts at CEN

The QED Performance QE7711 is a 3m RCA subwoofer interconnect for connecting an AV receiver or amplifier to a powered subwoofer. It uses Solid Complementary Conductors, a ferrite impregnated absorption layer to keep digital noise out, a foamed polyethylene dielectric and gold-plated QED phono plugs.

Who it suits

The 3m length suits a subwoofer placed near the front of the room, beside the TV unit or a front speaker, with the receiver close by. If the sub sits in a corner or along a side wall, the 6m QE7714 gives the extra reach.

Our tech experts advise

Connect it from the receiver's SUB or LFE output to the subwoofer's line or LFE input. Measure along the actual cable route around the room before choosing a length. Keep the cable away from mains leads to avoid hum, and do not coil spare cable tightly. For more QED cables, see our QED collection.
