Okay so we do a mistake when we order the enclosure, it comes unloaded. So i keep my amplifier (pioneer) and decide to go for a pioneer subwoofer 10". So i have a full pioneer setup (avic f60dab, gma 3602 and ts-w261s4). This is where we do the second mistake ... i will talk in centimeters ; the subwoofer enclosure from mtx have an outside diameter of 26.5cms and my pioneer subwoofer have 27.7cm ... i decide to put the "stickable foam" don't know the name of this sort of tape in english. And screw it to the enclosure with bigger screws. So my subwoofer is applied on the outside of the enclosure, but it looks well too ! No leaking of air or anything, but if someone take the enclosure unloaded, be sure to order an 10" subwoofer with maximum 26.5cm of outside diameter.
Built quality is very good, fit very well, the attach are simple but look not very good, price is a little bit expensive, but i don't regret it's a great product and i'm really satisfied !
For the bass, they are perfect, and also better than my previous 12" pioneer subwoofer, deep, punchy, loud.. great sealed enclosure!
Hope i give you some good informations and if you will to correct me in my english you can, i'm just a little frenchy ^^
