Thunder Round TR55 series subwoofers incorporate some of the same technologies as higher end MTX subwoofers including Spider Plateau Venting and Asymmetrical Linear Drive System which make them some of the best performing subwoofers in their class.  Featuring 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 these subwoofers look as good as they sound.

Available in 10", 12", and 15" versions in both single 4 Ohm and dual 4 Ohm configurations, these subs can be used in any installation type.
