Ya know I have an old Mmats 12" and I really like the sound.
I use it in my wifes car....
I had it in a large sealed box 2+cu ft so I ran it's parameters in Bass Box Pro and ported it.....
Tried three different tunings and settled @ a pretty high one
(high 30's low 40's cant remember)
Wife doesnt listen to any real bass heavy stuff
I honestly liked it sealed better than ported....
Good find for sure....Envious I am....
