Read this and decide for yourself if you think you can do it.

You can also do a search for re-foam or re-surround

Looks doable, I wonder where the best place to buy refoam kits would be?

I have seen some kits available with pleated/rubberized paper (like the 4311, L100) I suppose the compliance would be different but I wonder if I could use one of those (no more changing ever!)

I wonder whether there is someone local who could do the job for me? anyone know anyone in the lower NY area?

thanks, tony

Kind of like putting monster gumbo mudders on your Buick... wrong application for most. -grumpy

I put them on my VW... they do look kind of goofy now that you mention it.





khorns in living room 4311s in my study/office, guess where I spend more time?

:dont-know Sounds like a no-win situation to me.

D'oh!

Have they been in the speakers or out on a shelf??

That part, someone here can likely answer. Regarding refoam kits, you might want to
talk to Rick Cobb <[email protected]>. Not paid to shill for him, but I've used
his kits and been happy with the result.

I'm contemplating the task of refoaming six 12" JBLs (4x128H and 2xPR300). So far I have to say Rick Cobb has been very helpful in answering questions about the makeup of his kits, and very accommodating in offering to make up an order for me with no more or no less than what it takes to do the job right. I feel I'm up to the task but didn't look forward to having to pop the dust caps and shim the voice coil. Rick's advice and parts along with the help on this forum make it look easy. Even for a novice. This ought to get you to all you need to know: Rick Cobb

We'll see. Thanks.

The new foams will last a couple of decades, probably. A refoam every twenty years or so is small price to pay to maintain the bass performance of those speakers.

I've got a pair of 128H woofers rattling my room right now, definately worth the effort. My God they create clean bass.

[speakerdave]

Yeah. The 122 in the L65 is good too, although the speaker should be mounted on some kind of stand about a foot off the floor (my experience, anyway). The L65 is a nice speaker. The bass definitely would not be the same with a 4311 style woofer. On the other hand, if you want to use the L65 with a subwoofer, you could put in a different 12" and stick a sock in the port. I would not install the wrong surrounds on the stock woofer, though. That would permanently mess it up, and it would then require a recone to be restored to stock condition.

thanks for all the feedback, I hate the idea of having to do the work myself (I KNOW I will screw then up) but perhaps it is my only alternative. I did the job once on a pair of Inifinty bookshelves and it turned out ugly but workable so I guess I could tackle it. I will let y'all know how it turns out. Tony

I have had lots of work done by Millersound Labs in PA, They work fast, they only replace what is absoloutely needed, the results are like new from the factory, and the price is not much more than you will pay for the kit, and be stuck with less than great results.

Bill Legall at 215-412-7700 I can not say enough about the quality of his work.
