Interesting topic this is.
I have a pair of Wilson Watt/Puppies and, from the factory, they came equipped with "diffraction pads" on the front baffles
of both the WATTs (upper cabinet housing tweet/mid) and the Puppies (lower cabinet housing the woofers). These pads
seem to made of thin (perhaps quarter inch) mid density foam.
These pads on my speakers have now degenerated and I am thinking of replacing them; any thoughts on best options?
Wilson Audio sell pre cut replacement foam pads yet many of you here have discussed the possibility of using felt.
Are there advantages to be gained by using one material over another?
Thank you.
