Whats the best adhesive to glue ceramic magnets on Polk 6.5" drivers?

Im on my way to get some JBWeld. Im not sure which type I will end up with yet though. Probably doesnt matter other than avoiding obvious like types for "underwater use"; wood etc. I think there is a set with 2 seperate tubes and a set with 2 syringes together with 1 plunger for easy application.

Loctite Power Grab is what you want to use.
Home Depot carries it

I've re-set many magnets and have found 2-part epoxy to be the superior adhesive.

I used JB Weld, the original 2 part epoxy (the dark stuff). Takes a while to cure, but it really holds."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer

NF, what are the Sharpies and drill bit for?I disabled signatures.

Well I left before the Power Grab was suggested so I picked up some ACE brand Quick Set Epoxy (2 part) 1500psi. The power Grab looks like it is easy to work with and make inconspicuous. Im sure they all work fairly well if applied accurately.
I was a bit confused by the attchd thread that has pics of disassembled 6.5" driver along with explanations on how to glue it up. I was going to just run a bead along the top of the magnet (with speaker face down) where it meets frame. But it looks like the above thread has several other places it suggests treating.When freedom is outlawed, only outlaws are free... -
I thought I already cleared that question up for you. Apply it top and bottom, that's it.
BTW, if you got the 5 minute epoxy you're going to have some messy fun. I suggest you return it and pick up the Power Grab.Political Correctness'.........defined

NO KIDDING!! I did the drivers in my SDA 1C's with JBWeld before anyone around here started suggesting Power Grab and they look like fecal matter. I did 2 sets of spares with Power Grab. Sooooooooo much nicer and cleaner to work with plus this time I didn't end up gluing some Q-tip's, paper or my T-Shirt to a driver.“The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain -
Its best to apply it on both sides of the magnet filling in the corner where it touches the plated steel,

Maybe ill get the grab. I just bought a pair of CRS as well so Ill have a bunch to do at once. I wasnt sure about the dual tweeter version of CRS (esp with SL1000), but theres a decent deal on these in great condition now and I dont wanna wait any longer lol. I have a pair of Peerless I can drop in for the stereo SL1000's if I find the 1000's tiring, but I suspect I will like the air. These peerless are smooth and unfatiguing though, best thing about these 7's.When freedom is outlawed, only outlaws are free...

Peerless tweeters cannot be swapped around with any other tweeter Polk used except, IIRC, on the RTA-12B and C's which have the same crossovers regardless of tweeter. The Peerless tweeters absolutely crush the SL1000 and SL2000's, you will find that out in short order.afterburnt wrote: »They didn't speak a word of English, they were from South Carolina.

Yeah the crossover is my worry, hopefully someone will chime in with a solution. I measured my Peerless both at 3. whatever ohms DCR (4 ohm impedance) but everyone keeps saying they are 8 ohm. Is there a known conflict with switching Peerless for Sl1000s in CRS's or is it merely potential problem bc of crossover change?
I had the SL2000's and can recall the fatiguing spike but I also appreciated things about that tweeter.When freedom is outlawed, only outlaws are free... -
The CRS never came with SL1000 or Peerless tweeters. You cannot drop the Peerless into them either. Get the RD0194-1, which is the proper tweeter and better than the Peerless.Political Correctness'.........defined

Well this 1984 pair has them in it. 4 of them. Ive heard that they even came with Peerless.When freedom is outlawed, only outlaws are free...
-
I don't think they came with peerless. They did come with the SL1000's in the early dual tweeter version. The main point that needs to be kept in mind, is that they are NOT interchangeable due to differences in the crossover. Best thing to do with all models is to upgrade to the RDO194's. No need to keep going around in circles on this.

I had them in and out a couple times, but that is what was in them when I got them from a guy in Knoxville.

SOB, after hunting around online......yep, very early (1983) CRS came with SL1000's.Political Correctness'.........defined

Id love to hear people summarize that...
I am pushing the Peerless bc 1) I have a pair on hand already and 2) they should fit the SL1000 routing. I would love to hear WHY the Peerless would be a poor match for the above model, I think the schematics are available here:

Because the Peerless was never used in any SDA speaker. That I am 100% certain about. You can't go swapping tweeters or drivers around just because they have the same resistance. There are many other important parameters.Political Correctness'.........defined

I think the 2nd link I added is of the SL2000 bc it notes switch from fuse to protection. I havent seen an earlier schem.When freedom is outlawed, only outlaws are free...
