Sealed 8x10 Question

[basey]

Hi,
I was reading on the DuncanAmps site and came across something that made me think.

Try and stay away from speakers with cloth accordion or treated paper surrounds for any designs other than open backed. The surround on these speakers can be a large source of air leaks in sealed enclosures, which results in lowered efficiency.

When I read this I realized that almost every 8x10 cab I've ever played, including the one I have now, has cloth or treated paper surrounds.
Should they be sealed?
Is there any way to seal them without ruining them?
I never thought about the air coming throught the speaker.
What do you guys think?

I've never heard of it being an issue, and the Ampeg 810 fridge has been rocking for many years with nary a problem from such things...

Duncanamps deals with mostly guitar stuff anyways.

I believe that surrounds are usually treated so that they withstand flexing for a long time. Because of this, I doubt that they leak any air.

How's the Sonic doing?

Thanks for the replies guys.
The sonic I got from you is a great cab. It sounds better than most 810 I've played through.
I disconnected the bottom tweeter because it was a little too bright at first.
The DB750 and 810 is pure sonic destruction!!!

But, I need to replace two speakers, that are starting to rattle.
It makes sense that they would be sealed, I guess they just dont look that way from the outside.
Thanks again for the great deal.

BTW the songs on the ILLINOISE myspace were recorded with it if your curious.
