Peter Gunn is one controversial guy and I will leave it at that. I like the one post where it is indicated that the stock x/o circuit was designed by Nelson Pass. In my case, my 2.5's were upgraded to the x/o's in 2.6's and Mundorf and Jentzen caps were used as well as better inductors. I cannot say if they sound better before or after as they were done before I bought them.
The most important thing is if the end user likes them or for that matter any speaker.
