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. 

The UnderTaker Series is designed for Extreme SQL applications (Sound Quality Loud) and Extreme SPL applications (Sound Pressure Level)

    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.
