Can someone tell me the thickness of the gasket ( part no. 20253 ) as used with the 128H-1 in the 4412 / 4412A Studio Monitors? For a current project (128H-1 in the 4410 Studio Monitor cabinet) a gasket with a thickness of .05" is needed.

The gasket # 20253 is listed as being vinyl. Could two of these be stacked, if necessary, to obtain the .05" thickness I need?

If not, what would you recommend in the way of a suitable gasket material? A very carefully cut piece of stick-on vinyl tile with a thickness of
.05"?

Thanks in advance for any assistance.

Just use 3/8" wide x 3/16" thick vinyl foam weatherseal
Cheap, compresses easily, seals well and is easily removable
For some reason the brand name, made in U.S.A. "Frost King" stuff in this size is in all of the .99 cent stores as well
Comes in a 17' roll
The part number is "V443"
It's what I use now almost exclusively
Provides a better seal than the silicon JBL O rings and works well for caulk applications like the old ARs too
Compresses easily for a closed cell type so no cranked or bent frames

Not sure why you need such precision in the gasket spec. Anyway, doubling the O-ring does not sound like it could work. The pressure from fitting the driver would push one ring down and around the other.

For posterity, the thickness of the gasket is .015". There was a small piece stuck to one of the woofers that I was able to remove and measure.

Ciao, "d.e."

How thick was it before it was clamped into place, sandwiched between the basket and baffle for almost 30 years?
