Wow. Sorry. I thought that if you needed some speakers for the smaller sony APM's then I might have a pair I could sell to you.

But those bigger ones -- hard to get someone to part out those, especially the APM's.

I have a pair of speakers for the FH-7 that might fit, but won't look exactly the same. PM me if you are interested. They are not APM's but in my opinion, the non-APM's sound better than the APM's anyhow.

I saw that japanese procedure but I am quite skeptical about the results beyond just having something installed. Chamois isn't going to be nearly as flexible as the original stuff and the chamois was starched to keep the 1/2 rolled shape. Ever dried a car with a chamois and see what happens to the chamois when it dries? AND it wasn't even starched! The speakers that were refoamed are higher quality speakers than these boombox ones that could take higher power too. I just think that there has got to be a better way using better suited material.

Heya Nz Boom! I've used that PVA trick on one of my VZ-3000 speakers (vertical turntable Sharp home stereo) that cracked it's foam when cranking some dub on her a bit too hard. It held perfectly, and still is. I just covered the cracks on the front, but I think if you took the speaker out and put a nice thick coat over the front and back
of the surround it'd last for a LONG time! By rights, if you cover all the weakpoints on both sides it shouldn't begin to crack anywhere else.

Not sure at super high volume though.

Should be a good soloution for foams that are just on their way out but haven't started turning to dust yet.
At least until a better solution is found.


Rock On.

:agree:

Superduper, have to agree with you here.
It was just a starting point, but yes, chamois is not a long term fix. :sad:

Yes, this is a true point. :-/
Just opened a box last night and the main belt had become a gooey black resin....all foam had turned to dust :sad:
