Sean-The packaging costs more to make than the ringmat!..You should see it! Thick,high gloss paper folder with sleeves.Vibrant colors,cool designs on it.Lots of inserts and included in one folder,the Ringmat!
I bought one several years ago,so maybe they have cut costs these days and just give you a generic folder,dont know.
I used it on my P-25 but I did not hear an improvment over felt.
Before I sent it back to Audio Advisor,I went to a hobby shop.I bought thick paper just like the ringmat,a sheet of cork the same thickness as the ringmat cork and a hobby knife.
3 hours later I had a diy ringmat that looked almost exactly the same as the big guy.
I tried my diy ringmat on my P-25 and got a noticable improvement in bass.Go figure.
Total cost <$5 but no fancy folder for it.
