    Holy Cannoli!! Dude, I am so-o sorry. I had imagined something for more straight forward for a re-wire* 🙏🙏🙏😢.

    Is it too late to consider something else*?! 🙏🙏🙏

    Wow! I had to do the math and 16,18,19, and 20 gauge do indeed equal 12 gauge! However the maximum size I'd want to go to avoid the skin effect where the impedance of the wire is increased for the high frequencies due to the electrons preferring to travel at the surface is around 20 gauge. Actually I've usually heard 23 gauge. You've got 4 wires to twist together but I'm assuming they aren't enameled.

    I guess what I'm sayin' is if it were me, I'd use that wire for the mids and woofers, but, and taking into account that I'm probably OCD, I'd use 11.5 gauge Cardas 6N Litz for the EMITs. They're a crown jewel of that speaker and you wouldn't want to go to all that work and then have any doubts afterwards. My 2c.

    My bad, I quoted the wrong guy. Lol it should had been @EndersShadow getting it right that the rewire is going to be difficult and time consuming.

    I took a old AC cord and cut the plug off and will use it to power the DBS field. Should be cool to have 120v over 36v when I plug it into the wall.

    ANYTHING heavier than the original wire connecting the woofers, would improve the bass SQ. Same holds true for the lower* registers*!of the mids, something you may or may not like.
    *depends upon the HP frequency/slope

    While I HP’d my CC @ 80hz* as do many others, the first re-wire made ALL male voices, especially those like Darth Vader thick. The Tri-amp made “worse😊! So I “trimmed” (EQd) a little off the bottom couple of octaves - no 🍅s please🙏
    *can’t recall Outlaw’s slope

    So take these next steps carefully & patiently. Regardless of what wire you use*, the short term “pain & suffering**” is well worth the long term*** benefits***.
    *ANYTHING will improve - that OLD wire probably has some corrosion you can’t see
    **a one time thing unless you’re OCD
    ***until you die, sell them, or some other extreme life changing event

    May your fingers stay clear of your soldering iron. Tony

    Just finished fishing. No luck at all man! So after a short nap I'll start working on the RSII. I'll throw up some more pics in a bit. I found a really helpful thread over at AK where a member did a refresh on his.

    Impedance curve which I was wondering about (yikes!). Definitely goes below 4 Ohms, down to 3 and 2 Ohms in places:

    Looks like I am getting the Hafler XL600. After reading those lab tests I'm glad I'm getting it. Dont want to destroy my Carver.

    His Onkyo A-9070 amp which he said is rated at clean 140W into 4 Ohms went into protection mode with the RS II's.

    Another reason I'm waiting in a parking lot right now to pick up this Hafler. I'm glad we were able to make a deal.

    I tried to take the woofers out today but they are in there really good. I did not want to put a flat head driver under the rim and mar up the wood. I just put the screws back in and will give it more attention tomorrow. I may try a dead shot hammer on a small wood dowel on the rim of the woofer basket.

    Also with all the space on the back of the woofer enclosure behind the mids I may try to set the crossovers up there. I think it would look cool to have the crossovers outboard but not viewable from the listening position.

    The face of the woofer enclosure has some weird finish and texture. I may just clean it off, give it a light sanding and spray paint a gloss black finish with a clear coat.

    Get some glue on those bottom edges of the speaker frames. One of your pictures showed some potential delamination.

    I noticed in the RS II brochure above, the woofer enclosure was veneered instead of the speckle paint. I think I liked it better.

    I'm not 100% sure what you mean here. Speaker frames? Or the vaneer on the bottom of the cabinet where it meets the floor?

    I read on the Audiokarma forum that those large furniture gliders are useful for moving the speakers around on, so as to not further chip out the veneer.

    I love your passion, but the crossover is too large for that to fit given the curvature of the top section, unless you build spacers, etc, which I'd not suggest. Have you opened them up to get a look at it?

    13984303298_3d2a86c7f8_b.jpg

    Its screwed and glued to the back of the top woofer enclosure and is point to point wiring, so its not as easy as say Gimpods Boards.


    14167609221_26e877b1fd_b.jpg

    Honestly a re-wire would be enough of a PITA. I'd not recommend using CV-8 wire for that. If your dead set on it, I'd honestly order some of Dougs Furez 14/4, strip the outer jacket from it, and use that for your wiring. Flexible, cheaper, easier to route, overall a better option IMHO. It would still require you to drill out more space to feed the wires, especially between the crossover and the mid's/tweeters.

    Also something to mention, in theory you should have a rear grill AND some material covering the woofers so its dampened a bit. Mounting the crossover would mess with the open baffle configuration as well

    blogInfinity%2BRSII-5.jpg
    blogInfinity%2BRSII-10.jpg


    I've had a pair, and gone down the rabbit hole in planning to upgrade them, so here are my final thoughts on what I'd do.

    Minimum (cheap, easy to do)
    -Reseal cabinets
    -Regasket crossover portion of top woofer to ensure its sealed too
    -De-oxit the pots on the crossover
    -Clean drivers and wood
    -Verify surrounds still good, perhaps add add'l glue to the dust cap

    Max (pricey and gonna take some time)
    -Re-wire
    -Re-do crossovers (think REALLY HARD about the components you SHOULD replace v the ones you may WANT to
    -Re-veneer - good luck, I'd not tackle that at all
