Sealing Factory Tower Pods with Lights

[Memo]

Browsing Earmark Audio's web site I came across this article regarding factory tower pods with lights not being sealed airtight and how to seal them http://www.earmarkmarine.com/install...Craft-X-55.asp Article indicates this is done for sound quality not for moisture concern. I would have thought more for moisture concern more than sound quality. I see Earmark actually sells kits to seal the pods.
http://store.earmarkcaraudio.com/Xca...cat=392&page=1 Has anyone tried this? Does it honestly make a difference in sound quality?
Thanks!

That is expensive foam....

Actually the main addition is a 0.125" thick aluminum plate. You want to have an airtight seal and you want the method to be rigid, and not foam or sound damping mat, etc. Plus, you gain access to the lamp from the interior side so it should be easily servicable....like a bolt-on aluminum plate.

Yes, it makes a difference in multiple aspects. The tower speaker is specifically an 'air suspension' version unlike the cockpit 'infinite baffle' version. So the speaker is very dependent of the air spring in the pod. And you only get that with an airtight pod. It will sound better, it will play lower, it will handle more power, and it will last longer with the modification.

Not every OEM speaker pod with lamp needs correction. Inspect yours closely before making the assumption.

$22 that's it? I was expecting much more expensive..

The pods I have are the MC stock pods I can see gaps in the light side. Did MC made sealed lighted pods? Everything you say makes sense and the cost is minimal compared to other MC stuff. I was just curious why this subject never came up before with this many MCOCD’s in the forum.

I should have kept my big mouth shut. I went to order the aluminum disks today the price shot up from $22.00 to $175.00 Yikes!
Time to find some aluminum sheets and gasket.

I mentioned it a while back because when I mounted the tower speakers that problem arose kinda on short notice and I had to find a quick (not perfect) solution for it...
