As for your deep sub, Edmonton exchanger can produce very thick sphere's from 516-70. I asked them how thick one time. They replied 5 inches thick, I almost peed my pants,lol.

calculate that you will need 2.25 in thick or something like that.

<div>Scott,</div>
<div>Just a thought, instead of buying an old k250 and salvaging some
parts. Consider talking to Steve, and buy his Perry 1401 front end and
have a hull rolled to fit, 43in, you could put a real nice sub together
working around the Perry front end.</div>
