I purchased these for a pair of infinity rs2 bookshelf speakers and I had to do some substantial modifications. The fit was touching the woofer and the thickness prevented me from screwing the plastic surround that goes on top of the gasket. I ended up cutting the gasket in four pieces. grinding it on the inside by 1/8 inch and then with an exacto knife splitting the gasket in the middle. Lots of work but in the end the fit was OK. The fact that these gaskets took such drastic modifications without falling apart, to me, it means they are very high quality.
