That's what I did....If I remember right, I ordered them from Poco, sending
them the info on the rigs I was using and ordered 4 of them since they are
so cheap. If I can find a way to use them with my homebrew power
supply/battery setup with some kind of anti-ocillation and/or current
limiting scheme, and am able to find a way to test it without blowing up the
Omni 6's finals......
