QED Performance Subwoofer Cable 10m

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 QE7717

From our tech experts at CEN

The QED Performance QE7717 is the longest subwoofer interconnect in the Performance range at 10m. It carries the low-frequency signal from an AV receiver or amplifier to a subwoofer through Solid Complementary Conductors, a ferrite impregnated absorption layer, a foamed polyethylene dielectric and gold-plated QED phono plugs.

Who it suits

Choose 10m when the subwoofer sits at the back of the room, across a larger lounge, or when the cable has to follow a long route round doorways and furniture. For subs closer to the receiver, the 6m QE7714 or 3m QE7711 avoids surplus cable.

Our tech experts advise

Plan the route before you buy: around door frames, under carpet edges or along skirting. The ferrite layer helps on long runs, but still keep the cable away from mains leads and cross them at right angles. Do not coil the spare tightly behind the receiver. Browse our QED collection.
