I have two pair of Altec VOTT A7-500, I am loving VOTT's sound, but I was always curious the JBL woofers 2231A in the 4520 or in a horn cabinet and the legendary JBL2395.
I could not buy original pair of 4520 so have seen around in my storage and I found a pair of cabinets, which were made almost the JBL D31050's cabinet drawing without mid part only the two woofer part.
today was the first time when they gave sounds
Now I am waiting for my 2440 and 2441, nut I have a pair of Beyma 2" (they are not bad!) and I am trying the xocers, it seems the 3110A could be good for starting, but I am planing to build a xovers only for this speakers, maybe the members will help me
