Great build quality

This enclosure is one of the best prefab enclosures I have owned, I paired it with one of the 2 ohm x series subs, if you are sure you want to use the x series subs then this isn't a bad investment if not do not buy this because it will not fit a traditional 10 inch sub as the hole is to large, it is closer to a 12 inch sub. I am going to do some modification with one of the 12 inch spacers and a 10 inch on top of that one, so I can get some use out of the box.
