MTX Audio Thunder Speakers

MTX THUNDER40 Thunder Series Speakers

The MTX Audio Thunder Series Speakers will improve any stock stereo. Providing a rich full range to your car audio system, you won't miss any part of the frequency spectrum when listening to your music. The midwoofer has an extended low frequency range that will give you great bass reproduction even without a subwoofer. The tweeter will give crisp and clear highs to your music. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio in their products, and the Thunder Series is no exception!
MTX Component Speakers

Extended Low Frequency Range

Of course adding a subwoofer to your system will give you fantastic bass reproduction in your system, but with the MTX midwoofer's extended low frequency range, you will have a great bass response even without a subwoofer. For increased quality be sure to couple the speakers with an amplifier and notice the low frequency even more!


MTX Speakers

Build Quality

You will have incredibly clear response with the built-in tweeter, and plenty of Low THUNDER response from this speaker's Polypropylene cone. The concave cone design provides improved off-axis response.

great value!

The following review is for a previous version (TDX40).

I knew going in that I wouldn't be disappointed and I was right. These little suckers pump!! I put them on my BMW K1600 GTL and they are louder and clearer than the stock speakers. Having owned a MTX Blue Thunder bandpass enclosure, a 10" Black Gold sealed enclosure and currently using a dual 10" 100 watt Thunderform box in my 1998 Dodge Dakota, I know the benefits of MTX products. Big or small, their products rock!!

Good Speakers

The following review is for a previous version (TDX4002).

I needed some small speakers to fit into the kick panels on my 1956 Ford F-100 pickup, and these work very well. High quality and very good sound, simple installation and great price.

Before you buy, know this

The following review is for a previous version (TDX40).

This speaker has an awesome sound, but of course it does, 4 ohms. It looks very appealing, and has an easy installation. BUT if you plan on running more than 15 RMS to it, I'd be careful. Even after being broke in, this speaker seems to blow very easily. I'd recommend this, IF you don't listen to loud music. If you want a decent system to show off, and are looking for a replacement dash speaker, I WOULDN'T recommend this speaker. It cannot take the abuse, even when you run next-to-nothing power to it.

Great bang for the buck

The following review is for a previous version (TDX4002).

I love the sound quality of the MTX TDX4002 it gives me a clear crisp sound for my truck. I would recommend it to anyone that don't want to spend an arm a leg for some speakers. I am glad I purchase it because I had some Power Acoustics in there before and this sounds a whole lot better.
