I made a cat-5 cable, but only one and have not used it enough to make any conclusions. I believe that it is probably suited beter for power amps with speakers that draw a high current 4ohm load like Maneepans or Carver ALS. I think the magnet wire for speakers will work good for tube amps conected to sensitive speakers. I will be trying the magnet wire in the future myself.

Edwin,
The best way to put it, is that the 2-pi's go much higher on the top octaves, the bass seems to go about the same as the JBL 2226's, What the 2 pi's lack is the "larger than life" soundstage. I don't think the 2 pi's soundstage is very wide or deep compared to the 4 pi-pro's. When I play certain music with the 4 pi-pro's, I feel like I am there and can get up out of my chair and join the musicians. I hope nobody gets the impression I am ragging on the 2 pi's, the cost factor is unbeatable, but if you get the 4 pi parts, a definite improvement. I am still waiting for the Alpha 10 to break in though.
Regards, Ron

Jabberwock,
The lenses I described are thin pieces of metal or plastic that disperse the mid frequencies more than the highs (at least that is my theory), The ones I have came from pair of Sansui SP-9X something or other that I bought while overseas in the Navy back in the 70's and 80's, They are plastic but I think they do help tame the bright peizo sound some. Maybe someone on the forum here can find old JBL speaker system with the lenses and post link, I have sore throut and sinus problems today, so somewhat braindead.
Regards, Ron

I "damped" the tweeter on my 2Pi's with my fav damping material- Xtreme Dynamat, which is made for car stereos. I put 3 small square pieces on the sides of the "horn" (facing inside of cab) and 3 narrow strips around the inside of the rim. I was trying to smooth the trebles out, but to my surprise it really tightened up the mids and the bass! I also used the stuff inside my CDP with incredible results.
