OLA foam surround source

Recommended Posts

I have some masonite ring OLA woofers that need new foam surrounds.I have done a few refoam jobs on other speakers using low cost generic foam from MAT Electronics. .I know that the OLA woofers are glued from behind so can I use a generic 10" foam surround on these? I can get the job done for less than $3.00 using generic surrounds as opposed to $20-25 for one of the eBay kits. I suspect that the eBay sellers are sourcing their foam from the same supplier as MAT and are charging a premium for instructions, glue, packaging etc.

Can anyone recommend a good source for masonite ring OLA woofers foam surrounds?

Thanks!

This is the way to go. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=261170146644

If you don't want the complete kit, email him (John) and say you want just the surrounds & dust caps. You'll get a better price than the kit price but not, I'm certain, $3.

I assume you have the 10" metal frame and not the one with the Masonite spacer: http://www.ebay.com/itm/Original-LARGE-Advent-OLA-10-Classic-Speaker-reFoam-Two-woofer-Kit-/330873956764?pt=US_Amplifier_Parts_Components&hash=item4d099fe99c

NEITHER OLA woofer will do well with generic surrounds. Why take a chance with nice speakers? Get the surrounds specifically made for your woofers.

Actually, he did say he has masonites so he wants the ones in your second link, Kent. I bet either would work, though. Some places sell the same surrounds for masonites and all-metal woofers and I have used the all-metal surrounds on masonites and they work fine. The only real difference is that the outer flange is normally bigger on the masonite surrounds since there is a very large area to glue them to on the masonite but only a small 1/8" ledge on the all-metal.

The real factors that matter, of course, are the flexibility and roll size in which most generics are usually woefully deficient.

You know, I started to write an answer saying that I'd re-foamed the Masonite versions and they were a bit tricky, then thought "no--no one would ever use a generic surround on the Masonite version." Guess I should have re-read the O.P.

So yes, it's the 2nd link provided and no, the 2 versions are not the same.

M-Sound has listened to CSP members and other vintage speaker experts and has made great efforts to supply the correct surrounds for our speakers--not one-size-fits-all generics. Look at some of the previous discussions of 1/2" vs. 5/8" rolls, slant vs. straight edges and Boston style "filled fillet" foams.

M-Sound supplies very complete quality kits for novices and will also supply just the surrounds or just surrounds plus dust caps for CSP members. Just drop him a line.

I got my OLA surrounds from Rick Cobb. He has detailed instructions for the Masonite woofer. It was my first refoam job and while not a piece of cake, I didn't make any serious errors that couldn't be corrected. He provides a 30Hz CD for alignment - no need to cut the dust cap and use shims.

The new foams seemed to fit the speaker perfectly and his instructions were perfectly clear. I don't know if he would sell just the foams, but he might.

I also refoamed my wife's Boston Acoustic speakers. These required trimming the foam a bit but Rick had detailed instructions for doing so.

My latest refoam was a pair of Advent/1s. They have the same drivers as the NLAs. These WERE a piece of cake.

My favorite source for surrounds, MSound, is changing from ebay to an internet store and he also switched ISPs so he's a little hard to reach. BUT he will respond to emails and sell kits or even just the surrounds. You can reach him at msound@shentel.net
