I’ve got a pair of the 10’s and have no complaints. Originally had just one and it sounded ok, I just wanted it louder, so I ran true duals. They had rasp until I put an x-pipe in. Probably would sound better with an H but it’s still deep and throaty, and can be loud if I really get on it, but isn’t bad if I’m taking it easy. Dumped after the axle is a must with those though, I had them dumped just after the cab and it was way too loud inside.
