Hi all, I am looking at building some sub boxes for some 12" L7's. I want to build some boxes to participate in some SPL comps (only for a bit of fun). The kicker manual says that for the maximum bass you need a 3.25ft³ box (these are per sub) and also .77ft³ extra to build the port, so in total I'll need 4.02ft³ per sub and a grand total of 8.04ft³ (230 Litres). Now thats a crap load of enclosure. And that still doesn't take into effect the building matter size and internal bracing.
So i've done some initial calculations and I have discovered that a dual box just won't be able to be lifted into the boot, due to the lip of the boot being considerably less than the metre I need to box to be. So I have decided to use 2 single boxes. But basically each box will be 50cm wide, 38cm tall and 67cm deep.
So is there any problem with having a box that is deeper than wider?
Also I was planning on using metal corner brackets in each of the eight corners and 3"x3" triangle shaped bracing on each joint, so 12 in total. Is this enough bracing?
Also is 3/4" MDF strong enough? The guy at WOW who is very good says that these L7's blow apart pre-fab boxes easy.
Thanks everyone.
