    Default 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:
    • Clean Mids/Woofers with Maguires Protector Ultimate x 6
    • Wipe entire cabinet down again with Old English Lemon Oil x 2
    • Reseal the cabinets with Loctite Loctite Power Grab Clear Acrylic x 2
    • Regasket removeable xover panel x 2
    • 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

    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:
    • Clean Mids/Woofers with Maguires Protector Ultimate x 6
    • Wipe entire cabinet down again with Old English Lemon Oil x 2
    • Reseal the cabinets with Loctite Loctite Power Grab Clear Acrylic x 1
    • Regasket removeable xover panel x 1
    • Regasket Mids x 6
    • Re-Foam the bubble wrap woofers x .5 (got the foam on the woofer and its been drying overnight. Attach it to the basket today.

    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

    On post #4 of this link, someone scanned the original brochure for those speakers. Thought you might dig it.

    Hey!...Is your wife single? Is she looking for a husband because my current wife barely lets me get a full wipe after a poop 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.

    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 )

    Isn't that what you guys are always talking about?

    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!
