Just wanted to say thanks to Wayne for the great design. I had been looking at building these for a long time, and am sooo glad I decided to take the plunge. Made a few changes to suit my taste, but kept strictly to the measurements and dimensions. Can't tell you how amazed I was when I first heard them! They really sound great with almost any type of music. Now I am going to build the flanking subs and will dive into the 4's very soon. I have been building speakers for a very long time, and have to say that this simple design has really got me going again. By the time I'm done, I'm sure I will have built every speaker that Pi offers. Just a few pics to add to the many great ones! Cheers to all! Jon
