Post Subject: I think "the Russian" is simply trying to control diffractionPosted by rickmcinnis on: 6/12/2011

I have used thick wool felt around the perimeter of my round horns at times. Having owned a pair of ROGERS LS3/5a's in my youth and being amazed at the huge sound those little speakers could effect one tries to re-use ideas. Diffraction control is a worthwhile pursuit. I, too, was disappointed with how Dr. Edgar flattened the front of my horns which led to my suspicion that some kind of diffraction control was needed.

For some reason many years ago I removed the felt. Makes me think I should give it another try.

The EnABLE idea is fascinating but I have never tried it. I do not remember the tape remaining on any of your horns. One thing to stick the dots and dashes on a five inches speaker cone. The thought of placing those all around the horn made me weary. Are you still experimenting with this?

I think you might find some value in Mr. Purvine's ground things. One wonders if, at the high state of development of MACONDO, there is anything to gain but like all tweaks what is gained is usually unattainable any other way. In my experience they added gracefulness to my TAD 4001's (along with lining the back chambers with wool felt).

Could very well be that the VITAVOX does not need whatever it is these things do.
