Style and Power

Designing a subwoofer with spectacular bass response that looks as good as it sounds it pretty tough to accomplish. MTX Audio’s Thunder Round series has notoriously been powerful, durable, and a no nonsense type subwoofer. Not only can an MTX Audio TR4512-44 handle 250 watts of RMS power, but with its laser etched MTX logo this subwoofer is sure to impress when people wonder how you packed so much bass in one small sub.

Designed with a silver polypropylene cone with a raised MTX Audio and tribal design logo, a stitched rubber surround to ensure extreme durability, and a solid silver stamped basket, these subs look as great as they sound.

If your looking for Hard HITTING subs & your on a budget look no FURTHER!!! These are IT!!! I'm very satisfied with the way these subs bump, and the clarity that they have is of what you would expect from a more costly sub. MTX done a exceptional job with these subs, and like I said for your buck you can't go wrong!! I purchased some more expsenive Rockford Fosgates before I bought these, and these beat those HANDS DOWN!!! I would DEFINITELY buy these MTXs again, and of course from SONIC ELECTRONIX!!!

If your building a system for the love of music, and not to make street noise. Then I would recommend you order one or two of them. My system is all MTX and it sound so sweet.
