The Socket phase plug made the driver sound smoother by taking out some of the nasle, honky sound. Also the speaker, stock, has a hole in the dust cap that whistles at low frequencies. At 45 hz you can stand 3' away and feel the air hitting you from the hole.It's a 15/16" craftsman socket 3/8" drive. Carefully cut the dust cap with an exacto knife. Soon as the socket gets near the magnet it's going to suck the socket quickly, so be carefull. See pics in my gallery.

Yes, and they make a very noticable difference to me!
Are you using the standard "shallow" or deep socket?
15/16" craftsman, 1/2" drive.
15/16" side to inside, 1/2" side facing out.
The brand name of course doesn't make any difference, but that's what's used, so those are the dimensions to look for.
It is said that the concave part on the 1/2" side is important.
Also, some people report it helps to wrap the outer part of the outside edge with something soft: e.g. a ribbon of cloth, although I haven't tried that yet.
