HD 12"

HD woofers were designed to be fierce, different & unique.

Not many SPL oriented woofers were able to match record braking scores together with qualities reveered in various sound quality organisations. Even in small sealed enclosures, this woofer will keep on delivering bass in excessive quantities.

The dual 1 ohm 3" aluminum voice coil is snugly placed in a 4 x 78 Oz magnet, with a ventilated t-yoke for increased cooling. A 3 layer black nomex spider with enough rigidity for both SPL & musical use, offers superb suspension along with the tall rubber surround.

*It is essential that our woofers are given time to allow the suspension to soften up. Depending on usage, this may take several weeks. While this process is undergoing, it is not recommended to apply full amplification power according to the woofers specs. Once the moving parts have been broken in, the performance of your subwoofer will increase.
