Product Description
Welcome to Team GP's UnderTaker Series Subwoofers.
Hand Built In The USA
Whether you need to dominate the musical average classes, or a peak frequency burp in the lanes, we have designed a driver capable of handling tremendous amounts of power efficiently and continuously thanks to the monstrous GP UnderTaker UFO style motor. The UnderTaker motor utilizes precision cooling and drives a 4 inch 8 Layer high temperature voice coil. The motor's "bottomless" design allows for ridiculous peak to peak excursion with zero risk of bottoming out. This instantly eliminates a common point of failure, and is designed entirely to be forgiving in the most abusive applications all the way to the triple joint which is also extravagantly reinforced for added durability.

BEST OF THE BEST !!!
These subs are absolutely insane !!! I’m talking the baddest of the baddest !!! You always hear people talking about Sundown this and DD that and Skar this and crossfire that but once you hear these it’s over…The musicality of the sub blew me away I was shocked at how good it sounded and when it comes to the lows it just demolishes everything I have heard with bone and teeth rattling lows !!! Best subs on the market hands down I would put a undertaker against any sub out there

These things are beasts. I can't wait until they are broken in. Everything I've ever done with Gp turned out to be a great experience. Buy them and thank yourself later.
