Sansui Cloth Surround Restoration?

I had a couple threads way back. Based upon what I have done previously, I say put your time and effort into keeping them original and treat the surrounds. If your not happy with the results then grab new woofers or replace the surrounds on the old with foam surrounds. :dunno:

Is anyone still monitoring this thread? Has anyone had any real success with a permanent fix? Where are you finding the "AR sealant"?
 
The sources are mentioned in this thread. You can contact @RoyC here on AK. I believe he makes it. Or you can go on ebay and get it from VintageAR. Search for cloth surround sealant or sealer. Cheaper direct from Roy.

Thanks for the info. I saw Vintage AR listed as the seller, but can't find him on webay. I will search again using vintagear as one word.

Thanks again.

Found it! vintagear, one word. Doesn't show any sealant in his listings, I've sent RoyC a pm.

Thanks again.

Search for speaker surround sealant or words to that effect. You'll find it. In the past you would get a larger bottle for the same price direct from Roy.

VintageAR dope is this. Have used it twice on old KLH speakers (Model 17 and 6) where their original dope had largely flaked off leaving mostly bare fabric. Sometimes does large size may contact to see if is doing or can do another batch. Largely bare surround Model 6 woofers needed more one standard small bottle to get a good seal. In the past has shipped it out in a timely manner.

Picked up a pair of SP-200 myself have not done much with them yet, have the caps from PE to install. Will have to check the surround, may be doing this trick and get the large container from vintageAR.

Let us know what response you get from RoyC.
 
Sorry, the ebay guy is vintage-ar. He has the sealer listed. Just do a generic search with general terms. You'll find it
 
@doctorolds should be, he'll probably stop by later. You don’t necessarily need to dope the surrounds. The cabinets aren’t sealed. I think a little toluene on a a tip loosened up the originals just fine. Then? Use the darned things, that’s the real issue. AK member no longer here 427 just used his, pounded them into submission. I’d show up and he’d have 4 going at once pushing 100 watts to each one, situation handled.

Well, it's been a while since visiting this thread, but great results have been achieved by a few members that have tried it. Is it permanent, I can't say. The main goal is to carefully remove the hardened sealant from the factory and then use the @RoyC sealant to keep them pliable. Most comments in this thread cover the removal old sealant, but a search will provide more results. Go for it, the bass response will definitely improve. Good luck.

Hey there, I am also restoring a pair of SP-200s. So far, I have done DOT 3 brake fluid on the woofer surrounds, which softened them nicely, but left the surface quite sticky. Maybe I should have sprung for the Vintage AR dope, but I'm a sucker for a good home remedy. I recapped one of the crossovers yesterday, and it has made a dramatic improvement in clarity. Will do the other speaker tonight, now that I have had a chance to compare old to new caps.

Question - should I also treat the surrounds on the midrange drivers? I guess it couldn't hurt. Or could it?

Let me know how your project works out. I plan to hook my 200s up to one of my smaller receivers and gift it to a friend. I think these old Sansuis are a great choice for a vintage look and adequate sound that gets the most out of 25 WPC or less. Those types of receivers are still relatively cheap and easy to find, but often they can't do justice to modern speakers.
 
I guess I'll go on & apply the new sealant on my 200s, but it's a ported cab.
Is the sealant really necessary?
 
I just played the H ll out of mine. They loosened up and the bass is very nice. I also found they had better bass when paired with a Tube amplifier.

I think most all ported speakers still seal the speakers to the baffles. Just a thin smear of clear latex would not hurt. Is cheap and easy to do.

It is not necessary, you are correct. Just pound on them for a bit, the surrounds will loosen up.

I prob have just enough ar stuff for a light coat on both & don't really see a down-side. Was just curious though on the ported thing.
I have some solen caps in route (whenever that happens).. but all the drivers are alive.

I want to give a big shout-out to all you guys and your wierd audio addiction. I'd like to thank you guys for all the info, but also suggest you seek counseling.. oh,,, uh, nevermind, as you were....carry-on!

The downside is that you’re adding mass to the surrounds, and you’re making them stiffer. Both result in less bass, and a slower less articulate bass response.
