I am ready to install my Larry's rings and I bought some Mortite putty and was wondering what everyone does? Add the Mortite or leave it alone? As always ,thank you for all the help. Darryl

    Stock gaskets in good condition? If so, you don't need to do anything. If not, use Armacell, do NOT use Mortite.

    ^^+2^^ Stay far away from Moretite. Armacell is great stuff.

    Has anyone tried silicone caulk instead of Mortite or Armacell? Seems like it would seal well and be easy to apply.

    You mean like bathroom silicone caulk? Not a good idea for many reasons including you don't want silicone anywhere near your speakers.

    The problem with silicone caulk Jim, is that when/if you need to remove the driver the caulk sticks both to the Cabinet and the driver flange. If you ever remove the driver again, this usually results in the caulk tearing off some of the MDF cabinet material and also can tweek the driver basket (Distort the Flange). The caulk does make a good air seal, However; as F1nut shared, stock polk gaskets (in good condition) or armacell work great. Something to consider about driver mounting: You are not only trying to get a good air seal, you are also trying to have the driver coupled to the cabinet, Some sealing materials create a cushion that allows the driver to move in/out, thus losing the dynamic impact the driver may be able to produce. and lastly, you want to be able to remove the driver without damaging the driver flange or the cabinet.

    Thanks F1 and dscheer. I was sure it was a bad idea, because I haven't seen it mentioned here anywhere and it would be easy to apply.

    I googled Armacell and there are a lot of different products but I couldn't tell what "model" exactly would be appropriate. Is it similar in application to Mortite, which I have used in the past?

    Armacell can be readily found at Home Depot or Lowes. The one I use is designed for windows and doors. It's very easy to work with and works great. I don't see any reason to use anything else (excluding Brgman's gaskets of course) if you need some sort of gasket/sealer for your drivers.

    I found that Armacell tape was a better seal than Mortite with Larry's rings. My comparison notes are here: SDA-Driver-Seals-Original-Foam-vs.-Mortite-vs.-Armaflex-Foam.
