Description

Just Added to the Xterminator Lineup!

Meet the U.S. Amps Xterminator XT18.

The Xterminator family just got bigger, louder, and meaner with our new 18-inch beast. Built for serious low-end authority, the XT18 is coming in hot with heavy motor force, serious moving mass, and the kind of low-frequency potential bass heads are going to want to hear for themselves.

The XT18 was created for bass lovers who want to step up into a larger platform with more cone area, deeper output potential, and the classic Xterminator attitude. This is the subwoofer for builds that need to move serious air while keeping that aggressive U.S. Amps identity front and center.

Designed for big daily systems, demo builds, and serious low-frequency setups, the XT18 brings the size and presence needed for customers looking to go beyond the standard 12-inch and 15-inch platforms. With its heavy moving mass, strong motor structure, and low Fs, this subwoofer is ready to bring deep bass energy to the Xterminator family.

If you have been waiting for an 18-inch Xterminator, this is it.
