I just like the way his sounded vs my old setup 2 15 inch l7 a memphis mojo 2500x1 and a 9.0 cbft enclosure tuned to 35htz his was everybit as loud as mine was but the pressure build up in the ears and chest were pretty intense and he had half as much in his as I had in mine so that is why I wanted a budget build with 4 15 I know I can get louder with 2 but I love cone area
