Default Gaskets!

Not that this is mind boggling but wish I had done this years ago. I have have been using rope-caulk to set drivers for a long time; works great until its time to take the drivers back out (pulls the wood out).

First cut the exact hole in scrap wood; then sandwiched gasket material in two other scrap pieces and re-cut. Next step flip woofer over and screw down, cut around driver with care.

Gasket material is easy to fine at auto parts and ebay.

*Tip of the day: attach every thing down -solid! A lot of projects are ruined because of hurrying and short cuts.

I like something a little more flexible, so I use thin neoprene draft excluder strip. As for fixing everything down solidly, I agree, but if it's a 15" driver or above, run some 15Hz tone through it whilst you do, it's very easy to warp the basket and get a VC rub if you tighten unevenly.

Sorry, no. I just buy it from my local old fashioned hardware shop. I think the glazing industry uses it as well.

I'm going to try some thin cork next, the material in the pic was gas/oil type.

I think something squishier than most automotive gasket material is needed. (The cork gaskets used for stamped valve covers and diff covers might be OK.) Closed-cell foam weatherstripping seems like a good compromise.

On this side of the Atlantic it is usually called "weather strip". When the driver doesn't come with a gasket, it is my goto. Stick it to the back of the bezel.

Something like this. Ny Home Despot has a selection of sizes

19/32 in. x 17 ft. EPDM Cellular Rubber Auto and Marine Weather Strip-01033 at The Home Depot

Parts express sell a proper gasket on a roll, it is very good.

I agree, however this worked nicely because the woofer is cast. The perfect fit is nice also.

The idea here was to sandwich the material in two pieces of scrap so you can use typ wood cutting tools.

Never thought to look on PE, gesh the supermarket speaker store
