When you want more wiring options to get the most performance from your subwoofer, check out our Dual Voice Coil MM840 8-inch subwoofer. It's the same easy-to-install compact size as the Single Voice Coil. And it has all the MM signature features: carbon composite baskets, powerful motor structures with oversized voice coils.

The MM840 punches out real tight, real serious bass, the kind usually found only in the most expensive systems. With 250 watt continuous/500 watt peak power handling, we recommend the MM840 for small sealed (.35 cubic foot) enclosures.
