Re: Help with a dual 10"
You could easily build a sealed one for around 30 or so before covering it. Ported would probably be the way to go with audiobahns, but sealed is much simpler. use 3/4 MDF (medium density fiberboard), some decently skinny screws around an inch and a half-2 inches long. Silicon sealent around seams. either a speaker terminal or just run wire through a hole and seal it shut. you should also really countersink the screws, though the kit is somewhat expensive, i've got one from sears and its worked well, dont know how much it was, got it for xmas. but that should be about all you need, just search for box building or what not on the board and you'll find an endless amount of info.
