DX12 in Sealed Box

puckster

I have recently installed a single DX12 in a custom sealed box. I built the top mount box as per the directions on the Polk Website and is fully sealed. It sounds very nice with a good tight bass. I had the hatch open this weekend to take a look at the "sub" in action and I noticed that if I put my fingers near the edge of certain spots around the sub, it seemed that I could feel a slight amount of air escaping from the sub-box, obviously from the area where the sub is top mounted to the box. Yes, I installed the enclosed gasket before mounting the sub. Should I torque down the screws tighter? Should I add silicone in conjunction with the foam gasket? Is this of any concern? Or is this normal?

Thanks,

Ken

Thanks for the reply Kim, but I', mot sure if you read my post. As I stated, I "built" the box myself using your instructions from the website. So it is not a Q-Form. It is also not carpeted. I used the gasket kit that was supplied with the sub-woofer for "top-mount purposes". So there shouldn't be any "gaps". My question to you is......Is a little air being pushed out of the sub around the rim, detrimental to the sub? I have read posts on other forums that "it is not the end of the world".

Thanks again,

Kim,

Thanks for the good info.
I carpeted my box I built for my Ford F-150 and after reading your post I see that I need to remove the carpet around my GNX-104's also and get a thicker gasket too. I cut out my speaker holes in the 3/4" MDF with a RotoZip tool so it isn't as true as it could be.
My sub box is down firing into the carpeted floor of the truck so I wonder if the 1" gap between the speaker and the floor is as detrimental to it as is the case with Puckster's post?

Thanks

Mike
