I have a pair of JBL 801C drivers and my first idea was to build Urei 813C clones. But i have read many times on this forum the 813's really performs better when soffit mounted. That's not an option in my living room.
Since the 801c driver is based on a E-145 cone and the E-145 were originally mounted on some 4530 it seems to me a good idea...but i do not have any technical background. What do you think ? Thank you.
