Thunderous Output

MTX Audio 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 TR55 series subwoofers don't hold anything back and also deliver the heaviest beats. These subs have a glossy black metallic paint on the polypropylene dust cap with a raised MTX Audio gothic logo, stitched surround for durability, stamped basket design, and a rubber magnet boot to enhance the look of the subs when reversed mounted.
