Default Anything to say on Speakons

I have seen xlr for speakers. Vox used 3 pin xlr for speakers with pins 1 and 2 wired.Ampeg used a 4 pin xlr on the SVT and other amplifiers. Speaker signal was pins 1&4 pins 2&3 were shorted in the cabinet jack and the B+ was routed through the cable to the speaker jack. This prevented the amp from destroying the output transformer from burning up without speaker termination. When the plug was inserted into the speaker jack, the B+ was fed back to the amp.
