Re-Purpose CW AT-15s

[robmorin]

Hello all, I found a pair of Cerwin Vega AT-15s in the garbage on the curb. Where I live people seem to chuck lots of good stuff. I hooked them up to a shitty amp I had lying around they sounded good, there was some cracking do to the cabinet being cracked... but the woofers themselves sound ok. Is there a way to test the woofers before I embark on a re-purpose build?

Anyways , I have a pair of AT-10's already and some other speakers that suit me well, however i could use a boost in bass with my DJ equipment. I was wondering if it's worth it to re-purpose these 15" monsters into a bass only enclosure?

I would power these with a sub amp. Can anyone point me to any plans or more detailed specs(Thiele/Small) of these woofers?

Thanks and have a great day!

Hi Robmorin,


If I was in your shoes (should I say your socks?)



1- I'd try first to remove each driver and inspect them thoroughly for any defects, if they all are in good shape then your lucky, you can take that opportunity to take notes on individual drivers and make some research online to find if there are any T/S parameters available



2- Evaluate if the cabinet(s) could be fixed (sealed) in some way (Epoxy Resin?)


3- Sell or enjoy them


I think It would be a shame to cannibalize them if they could be put back to shape.



From what I see you can have an entry powered sub for around 150US$

You won't need the specs if you patch up those original cabinets. Rewire the woofers (maybe eliminate the passive low-pass), block the holes for the mids, and your "bass-only enclosure" is finished.

Surround foam eventually turns into sticky tar and then dries out and gets brittle, but still appears intact -- until you touch it! So you should carefully figure out what state of decomposition yours are in.
