Looking for epoxy recommendation for securing older Polk Audio Monitor speaker magnet

Hello,
It has been awhile since I've been on the Polk discussion board. Apparently the board has gone through several updates since I was last active on it. I am looking forward to upgrading my Polk Experience here.

I am currently looking to figure out the recommended epoxy to secure the magnets in my small Polk Audio Monitor speaker collection. I have reviewed several threads here and online on the subject, but I wanted to get a solid response on a current epoxy product to use since there are so many varieties out there that others have experienced. The main reason I am asking is I am preparing to move at a future date, and I do not want to have my small Polk speaker collection misalign the magnets during the process of transporting them. I look forward to the informative answers.

I currently have the following Polks...
M4 w/Peerless tweeters (latest pickup)
M5JR+ (my first Polks, bought @HickamAFB Hawaii in 1990)
M7
M7 Series2
M10 w/Peerless tweeters
M10A

    Now is there a suggested prep before you use the adhesive needed before you use it on the magnet assembly? Like wipe/swab the area with alcohol to clean it before applying?...

    Never hurts to have a clean surface when using any adhesive/epoxy.

    When transporting lay them on the backs. You can also short the binding post with short wire or cable.

    Good info! Did not think to short the binding posts together when transporting them. Just curious about the reason for that?

    Keeps woofers from free bouncing as much. You're using the magnet, voice coil to lend some support.

    I was figuring it was something along those lines due to shorting them together at the posts. Helping to stabilize the speakers is a good thing...Thanks for the reply...

    I'm back to preferring JB Weld.

    I use this stuff. Nice and slow to set up and doesn’t ‘flow’ as it hardens. Hard after 1 day, really strong after 3 days. Can be smoothed out with a wet (water) finger.

    Been occupied with other items including family. Glad to know there are more options to consider...I have experience with JBWeld I've used with other projects but the PC-7 looks promising too...more research on the products until I am satisfied to commit...

    What is the reason we don't prefer the PowerGrab Ultimate anymore?

    Some felt the bond was not good enough on metal.
    I've used it on a few drivers as it was much easier than JB weld.
    My thoughts were that it would hold good enough to keep the magnet from shifting better than if nothing was there.

    Either way dropping a driver I feel all bets are off.
