infinity woofer as a sub?
hello I have a chance to get an infinity woofer from a sm225. does anyone know the specs on it as I'm thinking of trying to try it as a cheap sub. my problem with it though is I have no idea on what it's specs are and I've tried to search and can't seem to find any. then numbers on the sub are SM12GCF PN 333512-001

wondering if you guys might have any idea or if it would even be worth it to try this.

Based solely on this info it might work well in either a 'BIB' pipe or tapped horn, but that's probably it and you would have to measure its specs to do the latter:

Sorry to bump this old post, but I'd need exactly this woofer for said speaker.
If you could still get it, that is :)

Odds are, buying new is your best option:

what is a BIB pipe?
also how would one go about finding the T/S of the speaker? if I get that I'm sure I could do a little moer for the box.

eivind_E I wish I could help you out on this but only thing I can say is watch the papers. I found this one and the mid off craigslist and figured it could make a project speaker.

A conic or linear expansion pipe horn:

Probably either you or someone reasonably near you set up to do so will have to measure them.
