The MTX THUNDER681 is a premium 5x7" / 6x8" component speaker system engineered to bring high-fidelity sound to vehicles with oval factory speaker locations. As part of the high-output THUNDER series, this system is designed to provide an expansive, full-range listening experience with a particular emphasis on low-frequency response.

With its external 2-way crossovers and adjustable tweeter levels, the THUNDER681 allows for a custom-tuned audio experience that delivers "Thunderous" bass and crystal-clear highs even when powered by a factory head unit.

So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

Great play and chew toy!
Pattern Name: Star
The dogs love these! They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
