Frequently Asked Questions (FAQ)


NVX’s X-Series subwoofers are engineered for high output and deep, powerful bass. They are built to withstand extreme power output and hardcore performance without wear and tear during SPL applications.
It’s a custom-tooled die-cast aluminum basket with "X" bracing. It’s designed for structural strength, ensuring that the motor stays perfectly aligned even when the sub is moving a massive 30mm Xmax.
You’ll hit a 0.5-ohm load. This is for serious competition amps only. It allows your amp to dump its absolute maximum wattage into the sub. If your amp isn't 0.5-ohm stable, wire it in series for a safer 2-ohm load.
It’s a huge jump! With a massive cone and the same 30mm Xmax, the XCW151 displaces significantly more air. It’s for the enthusiast who wants "wind in the cabin" bass that you can feel in your hair and lungs.
Yes. NVX offers the XCW1251RC recone kit for this subwoofer. You don’t have to throw it away or send this sub back for warranty purposes. NVX got it covered.
