I found these in a Salvation Army today. The pic below documents the exact moment during a bass solo that the woofer surround gave way. Oh, well. That's one more pair of woofs to refoam. Orion says they were $275 new 20 hears ago and are now worth $45. I find that hard to believe, but I still did OK at $7.50. The sound was very credible from the one speaker that wasn't blowing chunks of rotted surround across the room. Lots of apparent bass, a la LS3/5A. These are surprisingly deep and heavy cabs for a 6" woofer. Not very sensitive. I'll fix them up and we'll see what we have here.

Man, you don't mess around do you?

I haven't heard that particular model, I have heard the PS-10 that shares the same tweeter. Pretty decent speakers.

Cheers,

Man that was fast !
Less than three hours too refoam.
Sheezz took me 3 hours just to get the old glue off on my first refoam job. Whats the secret?:dunno:

Cheap, fast and safe is IsoHeet, 100% isopropil, cost me $1.40 including tax at AutoZone. I use a 1oz jar with a dropper to apply.

So what your saying is to remove glue quickly use the IsoHeet !
Can it be safely used with paper cones? And all woofer materials?:dunno:

Thanks for the tip ;)

I don't use chemicals to remove glue. I just scrape it off. I don't like having to dispose of the goo after. I'd rather have nice dry crumbs abd scrapings. Frequently this is 80% of the work of refoaming. I use a cheap woodcarving chisel that I have ground into a good shape for a scraper. Doing it this way lets you have a good look at the frame, cone edge, etc. Then you can plan how to glue it up without mishap.
For removing old foam from the back edge of the cone I use a dental tool that I have ground to an edge. These things are invaluable and I keep a bunch in various shapes around for poking and yanking things. Great for anywhere a finger is too big to go.
I've done a ton of drivers and ones like this are pretty routine. It had an easy stamped frame and surround glued to the front of the cone. Inverted surrounds glued to the back of the cone are a royal pain. Don't get me started on Bose 901s. My eyes will never be the same again.
 
Nice speakers and nice job.

Are you "for hire"? I've got some surrounds coming for some JBLs, but I've never done it before. While I'm not opposed to trying it, I'd rather get my feet wet on something a little more disposable.

Ski;
Thanks for the compliment. I can probably handle JBLs and I don't cost a lot to do the work. I can work with you on them, show you how to do it or do it myself while you watch. It's a darn handy skill to have, and it makes the multitude of foamless thrift shop speakers look entirely different.
I still need to come down to your place to see your systems, especially now that you have that sweet Mac integrated. And the plumbing pipe speakers continue to fascinate me.
 
I sold a pair to Kam. They are nice little speakers and they are hefty for a bookshelf job.

I have one sitting on my desk running in mono off of my Gainclone. It's a very credible little unit that does a lot right. The day I got them, LVB and I were quite amazed by how they work. It almost makes me want to swap in some film caps in the xovr and paste some clay on the woofer basket to damp it. That might improve things but it's as much time as I'd invest in them.
