I enjoyed reading Russile's artical. For whats its worth, I made a 4 stack with the Fostex FF85K 3” FULL RANGE driver. They are very fast and are good to about 100hz-150hz. They did sound better with a single cap to reduce the lows. I was trying them out for a 16 high line array project. Comb filtering did not seem to be a problem on the 4 stack. The other driver I tried was the TANG BAND W3-594S (I think the # is correct). The Fostex was much better. I was trying to eliminate the x-over by using a fullrange. After hearing some ribbons tweeters I decided that the fostex was not the way I wanted to go. A 16 stack of those FF85k drivers would be #2 on my speaker list though.

I bought the Linus3 array that Rick posted about in July, and am very happy with it.
