As said, Mmats is great. I don't think you guys are giving them enough credit, they exceed the good rating. I would consider them to be an excellent company, hand making everything in their Florida build house.
Their amplifiers are their masterpieces; all being more than 85% efficieint, and putting out hundreds of watts over their ratings.
I have owned a couple Mmats subs; the Dreadnaught and the P3. Both were superb drivers, the Dreadnaught slaying my ear drums- it was by far the loudest single 12 I have ever owned or heard. I would even say that it was the loudest setup I had in my 98 Buick, and I also had an 18" 4HP in that trunk...
You can never go wrong with a Mmats product.
