Additional Information
MTX has taken subwoofer design and bass output to the next level with the introduction of MTX's new Thunder Round (TR) subwoofers. Available in 10", 12" or 15" sizes, 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 leader in the new Thunder Round line-up is the TR75 series. These beauties have a host of features designed for performance including a die cast aluminum basket, a black anodized aluminum dust cap (with a laser etched gothic MTX Audio logo) for strength, compression molded NBR surround for extreme excursion, and 8 gauge nickel compression terminals designed to deliver big power from your amp to these subs.
The TR55 series subwoofers don't hold anything back and also deliver the heaviest beats. These subs have a gloss 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.
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 (normally not found in comparable competitor models), a rubber surround (also not normally found in the competition), and a silver stamped basket, these subs look as great as they sound.
