well i made a wall face plate taped it in place and put a old infinity 12" off a sundown 1500 @ 4 ohms. it did a 140 then took the face plate out and tested the sealed box in back and only did a 130.1 so it's making me wonder. but the next problem was with the wall face plate in it went from 72hrtz too 57hrtz.was hoping it would be a little higher then that.but if i can see even an 8db gain doing a wall I think it will be worth it at one show.
we went with a wall just because of space.we are going to do 10 16volt PM and 2 xZ2's on the 1 18" DDZ. should be a fun time. the plan is to just do it for the one usaci show but if it does better numbers then i think I might go crazy and start a new wall do some cutting.yeah you never know
