MTX THUNDER65 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!

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!


With the swivel you can adjust the tweeters for imaging control. The tweeter will swivel up to 15°. The crisp highs will give your music the clarity it deserves.

Looking for bass?

Okay, first off....I don't have this model, I have the previous model - MTX Audio TDX65 Thunderdomes. Same specifications. I completely upgraded the sound system in my 2013 Hyndai Veloster and have a pair in the back. I changed out the speakers first, left the stock stereo in for several weeks. I wasn't all too impressed at first. Certainly, the sound was improved with way better speakers but nothing to get all misty about. After I finally changed out the head unit.....OMIGOD! These really do have a nice, low end sound. Very deep for their size. They're not super, subwoofer level, but I haven't installed the amp and sub yet and I'm almost happy enough without them. Some songs have such a nice low punch to them that I'm so impressed with these speakers. The only negative that I'm finding is with the sensitivity rating. These have a nice high rating, which is good to have. But I don't feel they're as powerful as my front speakers with the same sensitivity rating.When I'm adjusting the fader, I have to stay on the rear side of center to get good bass mixed with the front. Once I hit center, I barely hear these. I'm considering adding a smaller amp to power these speakers so I can set the level a bit higher than the fronts.
For the price and the specs, these are a really nice set of speakers for bass

Good solid coax

I've got these 6.5" speakers in the bed of my truck for playing music when I'm at car shows. They're getting around 100 watts each and sound fine!

Great speakers!

Excellent mid range drivers. Great bass reproduction and crisp treble. I couldn't be happier with my purchase. Well worth the money paid.
