Soundcoat was M&K's original vendor for speaker gaskets and the embossed 1/2" sound foam that they placed around their tweeters (such as the S-150's). This is a five pack of the 1/2" foam from Soundcoat; it's cut from the original M&K pattern for the S-150 size (although you can put them together differently to fit other models as well)

Demensions: .75" X 2.2" and 1/2" thick
