Earthquake's award winning Subzero subwoofers reset the standards of subwoofer construction, ease of use, looks and performance. Each Subzero may look similar in appearance but has been engineered with specific parts to accommodate the different sizes. These subs have unique baskets that are diamond cut with precision at different angles to give it a look that puts it in it's own high-end category. But the looks are just the icing on the cake, once you get a taste of this marvel of a sub you'll be coming back for more. Engineered with newly designed double and quadruple "Nomax / Romax" spider assemblies that assist in keeping the single piece piston linear; the accuracy in these subs are unmatchable. Also incorporated are the "PSP" terminals which are by far the best and most ergonomic terminals available today. The "PSP" terminal allows user to run the sub in either 2, 4 or 8ohm configurations and you only have to switch a fuse and reconfigure the fat 8-gauge speaker cables. Not only does the Subzero house innovative patents, it uses a high power and high strength motor that moves an over-sized, flat-wire voice coil. This type of voice coil offers much more surface area which always results in greater motor strength.
