Push the envelope

MTX has taken subwoofer design and bass output to the next level with the introduction of MTX's new Thunder Round subwoofers. These subs were designed with one goal, to bring the noise! Updating and upgrading the technology found in past MTX Super and High Performance Subwoofers, the TR Series has all the beef and brawn you need to be the loudest ride on the block. Whether you are looking to hit some sick SPL numbers or you want to roll with your favorite tunes, the Thunder Round subwoofers are up to the task.

The TR45 subwoofers round out the 2008 Thunder Round line-up and like their big brothers, these subs can bring the noise. Designed with a silver polypropylene cone with a raised MTX Audio and tribal design logo, a stitched surround, a rubber surround, and a silver stamped basket, these subs look as great as they sound.
