18 inch EXTREME Excursion Subwoofer, Cast Frame, 3 inch Made In USA Dual High Temperature Aluminum Voice Coil, 300oz. Dual Stacked Magnets, 1600 W RMS Power Handling


The ultimate mix of POWER AND PERFORMANCE is what the C7 Subwoofers bring to the table. Using the latest in development and manufacturing technology, Crossfire’s C7 Series Subwoofers are designed and built to play on the streets and the competition lanes. Utilizing numerous R&D hours, our goal was to deliver a subwoofer that has a balance of HIGH OUTPUT but can also play down into the lower frequency range, also known as the “LOW LOWS”. To make all this happen, the FEA optimized motor assembly incorporates a large 1″ inch top plate with a smooth extended bumped back plate to allow for a longer voice coil winding length. A multi-layer suspension was used to keep the moving assembly of the cone and voice coil linear and in complete control. The cone material is designed using a semi-pressed paper cone, coupled with a high density double stitched wide roll surround to maximize EXTREME EXCURSION. Keeping a balance of thermal and mechanical capabilities, a high temperature MADE IN THE USA 3” Aluminum voice coil rides along an extended pole piece with perimeter rear venting for the ultimate in cooling and INCREASED POWER HANDLING.

· High Grade Y35 250 oz. Motor Assembly
