All of our subs are built with American made coils!

 

These exciting new subwoofers feature an exclusive, custom designed and tooled radial roll cone, cast aluminum frame, and numerous other newly developed features.  All are dual coil models and work well in sealed or vented enclosures. You won't believe the bass!  Available in standard lead configuration and amazing new ILS configuration.

 

Some notes on this new roll - You won't find a better, more well behaved cone roll on the planet! This new roll does not invert, collapse, or pucker! Made from a proprietary material to exacting specifications for thickness and shape and gives the same designed performance at 120 degrees or minus 20 degrees. You just have to experience the new radial roll solution!
