Infinity RS-II Restoration thread

So I am going to use this thread to store all the work done on the RS-II's.
Upon picking them up I cleaned them using Murphys Oil Soap and then wiped them down with Old English Lemon Oil. That added a bit of color back to them and got all the mildew off of them.
Before:
After:
Then I started to dig in deeper to get my learn on. I came up with the following list of modifications I needed to do to bring these babies back up to spec:
Then I have these potentially optional modifications once I get em up and running:
I so orderd the parts, got in the cleaning supplies and got to work. Shout out to dromunds for sending me some dynamat. It hasnt arrived yet, but I am hopeful it will provide enough for my woofers and possibly the mids if needed.
I started with getting the woofers cleaned up and ready to re-gasket. The bubble wrap came off remarkably easy, but the adhesive was a different story. So far I think I've got 5 hours into cleaning both of them.
To remove the adhesive from the metal basket I used a combination of a box cutter, chisel and putty knife. Shout out to pitdog2 (Ivan) for the suggestion on the chisel. I got it back to 99% original. I didnt try to go back to bare metal, simply remove all the old adhesive.
For the actual woofer cone I used just rubbing alcohol. Its a LOT more tedious but I dont have to worry about messing something up.
I have 1.75 of the 2 bubble wrap woofers cleaned. I still want to try to clean the second woofer a bit more before attempting to install the new foam. I just got tired of doing it and set it aside for a couple days. My wife is picking up goof off today to help get the rest of it taken off.
Unclean woofer
Cleaned woofer
Unclean v Clean:
Woofer 2 where I left it
So I sat down last night to try and hammer a large portion of this stuff out. Here is what I got done off my list:
Here are some pics:
Unclean Mids
Cleaned Mid
The 1st cabinet took 1.5 tubes of Loctite. I figured I would rather SUPER OVERDO IT, than wonder in a year if it was enough or not. I must say the cabinets are both totally independent minus a small portion where the woofer wires connect from the top to bottom and wires to the midrange. And in those locations they used some sort of putty to close off the area that was still tacky. So I left it in place and just squished it down.
Unsealed Cabinets
Resealed Cabinets
Regasketed the removeable crossover panel.
Then I took a BUNCH of pics of the xover so I have them for reference:
Then it was on to regasketting the midrange's. That was obviously one of the easier things to do. I flicked the basket on these and honestly there isnt much ringing because they are so small, so I may or may not dynamat them. It will depend on how much I have left after I do the woofers, as those baskets ring a LOT more.
New Gasket in place

- Regasket Mids x 6
- Regasket woofers x 4
- Dynamat Woofers x 4
- Re-foam at least the bubble wrap woofers x2 possibly x 4
Then I have these potentially optional modifications once I get em up and running:
- Dynamat Mids x 6
- Re-Cap Xovers x 2
- Rebuild front grills x 2

No worries man. Cabinet one's loctite is still drying and I haven't even finished my first woofer lol."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
On post #4 of this link, someone scanned the original brochure for those speakers. Thought you might dig it.

Dan look at fatmat, much cheaper and it seems the same. Never hurts to have extra, nice project.

Hey!...Is your wife single? Is she looking for a husband because my current wife barely lets me get a full wipe after a **** nevermind restoring speakers.
In one of your cleaned woofer pictures, there's a god-awful toe located in the bottom right corner. I'd suggest cleaning with pure acetone and maybe some Lotrimin.Where’s the KABOOM?!?! There’s supposed to be an Earth shattering KABOOM!!! -

LOL... well here is how she looks at it... If I am upstairs cleaning the speakers/working on them then the 60" plasma is availible to watch Housewives of (insert any major city here), Sister Wives, Lifetime, Hallmark, etc...
So its technically a win-win (I have headphones so I can turn em up and tune the TV out)In one of your cleaned woofer pictures, there's a god-awful toe located in the bottom right corner. I'd suggest cleaning with pure acetone and maybe some Lotrimin.
Isn't that what you guys are always talking about?
Toe-in :evil:

Took some pics of the refoam job. My concern is that the gasket isnt the same around the speaker itself. Took some pics and videos (taking forever to upload, will post later)... tried to avoid as much "toe-in" as possible.

That re-foam job looks pretty messy. No disrespect, but just being honest. My first job looked like that too!

Do you have a schematic for the crossover? I've found TWO and they're different. One has the woofers in phase with the mids and tweets and the other has them OUT of phase with them (the woofers are still in phase with each other.) I'd really like to know which is the later version. They obviously changed it for some improvement. Don't know if mine are the original or the improved.

I just need to pick them up and then reinstall them

Here are some pics:
I've got 2 questions.
1. Can I remove/clean off that horrible orange gunk on the dustcover. I "assume" that comes off but havent really looked.
2. On the woofer I did (top one in first pic), is it possible to remove that Aileens tacky glue by getting it wet and carefully scraping it off?"....not everything that can be counted counts, and not everything that counts can be counted."

3. Aleen's will come off with warm water, and a microfiber cloth. Keep it wet, and keep going around the perimeter, until all the excess is removed.EndersShadow wrote: »Here are some pics:

4. The only thing I'd try on the dust caps, would be some fantastic or 409. You don't want to use any type of solvent, which might melt or damage the poly cones.

Awesome man, thanks for the tips. I will for sure try the warm water adn I may try the other thing too.
I just hate that there is that orange color on them but it looks like its due to some sort of weathered glue which may just be how it is.
