Well I've been thinking about what I want to do with these e-12s that are coming in here in a few days. I've built a box for them before and it was about 4 cu. tuned to 30 hz. I think it might've been a little too big for the power i was running. I also didn't think i was getting as much output as I could've had out of them. I guess I'd just like someone to chime in or maybe throw me a box to design for them. I think i'm gonna aim closer to 3-3.5 cubes tuned around 35 hz, i'll have them hooked up to a bxi1610, and its in the back of an explorer so space is pretty much open, max width is 40, id like to keep it pretty short, and depth isn't a problem, preferrably less than 26 or so. I'll probably throw up some ideas and if anyone else wants to chime in or give advice i'll take it.
also: if anyone would like to design a 4th order for these and give me the cut list i'll more than happily use it :P
