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 Handling70"


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.

    Crossfire C7-V3-18-D1 The best of both worlds!

    Posted by Scot McC on Feb 16, 2024

    My first 18 was to see if it would hold up to my demands. I have been slowly building my largest system to date.. The system now is 90% in. But lets talk about that first C7-18-1D, I built a 7cf single w recommended port displacement tuned to 30hz powerd buy a Taramps Bass 5K on an Epacenter wired to .5 with 64ah lithium, I put it in my hatchback wagon for about a month I slowly broke it in increasing the SPL to clipping. It is now two years later I have been trying to blow this C7 v3 at times on music w a AMM-1 hitting over 6k, so yea I now have 6 of them. 2 in my wagon and 4 in the big build I'm working on. It has all the goodies custom large case CES 390A at 16.8v to 1000farads to 144ah of LTO to DSP to Orion 17K SPLX to 4 C7s in a massive slide in that is 24cf after dis/port, built buy Bobby. The Kicker is the C7 is hands down the best sounding woofer I have ever heard plus it doesn't stink you know what I'm talking about some woofer if pushed hard smell like burning cluch and ass, after long seasons 3hs I have smelled it but just reduce volume roll down windows 10 min later you're back in business. 11 out of 10 and all for around $500 nothing compares. PS I'm 51yo been doing this 30 years+.
