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 TR4512-04 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.

hard kicking

i have 2 of these subs on a hifonics zxi1010 and running 500w rms to each sub and i gotta say one of the loudest subs i have ever had!

Great sounding, hard hitting

This is a great subwoofer for the price. It sounds great, hits hard, and has a cool design on the subwoofer. I have 2 of them hooked up to a 300 rms amp.

Pros:
- great price
- sound quality is awesome
- cool design is always a plus

Cons:
- nothing, just wish a had a little more powerful amp (like a 400 rms) to really get these guys going

I would recommend these to anyone on any budget!
