And also some woofers.
are gaskets primarily for use on closed design speakers?
thanks !

They seal up air leaks and stop related noises. Even on ported systems they should be used.
You may be able to feel a leak more with low bass, or use a match. Bear in mind that the pressure is higher
nearer the driver. Some pressed woofer baskets are not well formed and the gasket takes up the slack.
Leaks also can sometimes happen at the input terminals. Of course sealed boxes suffer the most from leaks.

good idea with the match.
or a candle so I don’t burn my fingers. Lol
does the gasket also decouple the driver from the baffle a bit?
can’t see how that really would work that well
If you want to check for leaks, do a slow sweep of your bass.
Decoupling, it doesn't have to float. A cone surround decouples cone and basket but not completely. Sometimes that is a good thing.

You need a very tiny leak in any cabinet or air pressure changes will push cones in or out.
I usually have a jack socket on the back so that allows a little leakage.

A while ago I thought I saw some Accuton drivers that had edge mounted gaskets for decoupling from the baffle, like a linear bearing I think.
This sort-of makes sense to me, but it's all part of a bigger challenge.
The ratio of magnet mass to cone mass should give an idea of the amount of displacement if the speaker is allowed to float freely. But if the driver is then clamped to a box, the system becomes more complicated for a couple of reasons.
-Partial oscillations as the box material bends at high frequencies.
-Offset centre of mass causing tilting of the magnet. As the magnet pushes/pulls on the box, instead of neatly sliding back and forth, the box 'wobbles' on its feet. Not to mention multiple drivers all interacting on the one box.

ok so here is the question.
if I put a gasket on my drivers and tweeter, how do I do that?
what material do I use ?
and also will the gasket lift the drivers higher off the baffle so they are not flush?
or will the material I use compress enough that it will not change height of the driver on the baffle?
thanks in advance
There are various approaches. Rebating is popular, making the driver flush with the front of the baffle.
Materials for a gasket vary, and can be foam, Mortite, etc.

what is Rebating?
is that choosing a gasket which will offer a seal but not lift the driver higher off the baffle?
thanks
Rebating is not a speaker term. It sounds as though your cabinets are already set for flush mounting. You want to learn what amounts of physical error do and don't matter.
Maybe because woofers would need thin, big gaskets that could easily be damaged.
Use speaker gasket tape when mounting woofers!
