Tonight, I built a 1/4"-to-Speakon cable using some 12 gauge Monster-wanabee cable I picked up for free from the local boom car shop. (They have a big box of short pieces that they can be persuaded to part with.) RTFM. I know it and preach it, but didn't do it this time. So, I assembled the Speakon using +1 and -1 for the signal, and screwed the thing together. However, I was supposed to use +2 and -2... I used the white bushing, which seemed to be the best fit on the 12ga zip cord (it has a very heavy jacket, and is a festive transparent blue). Now I can't get the collar unscrewed. It's locked up tight. How do I disassemble this turkey? Help!
So you discovered the one-way locking collar, eh? Just twist it off with brute force. They can be disassembled and reassembled a half dozen times before the locking tabs are sheared off. Nightbass
Aha! I wrapped both the barrel and collar in duct tape, grabbed on with two pair of channel-locks, and grunted. Victory! Thanks, Nightbass - I was beginning to think the three jaw chuck was jammed because I was using flat wire. There's no mention of the locking collar on the Speakon tech sheet. Sneaky Liechtensteiners.
