Passive Speaker Connectors
CyberHippy:
Heh, I recently rescued a couple of 10" Apogee monitors from a friends garage, threw some drivers in them from one of my bass cabs, and realized I'd have to create a couple of speaker cables just for those monitors because the connectors are…
wait for it…
Female XLR's.
Couple of minutes with my bag of replacement Neutrik's and the soldiering iron & they were up & running.
Gawd they sound great, but XLR connectors for passive speakers? I can only guess that they wanted to sell their own cables with them...

That was actually quite common on higher end gear in the days before SpeakOns :) . Most stuff was 1/4" or banana plugs / binding posts.

I hear that - some of the old passive Meyer speakers I work with at L'Audio North use funky oversized four-prong XLR-style connectors for bi-amping, never seen them anywhere else.
Google Image Search shows that four-pin XLR's come in a variety of pin layouts, his are like this:
but much bigger.

Yes, around the time that SpeakOn came out there was a competing series of connectors from Cannon (I think ?), those are what you have there :) . I've also seen regular AC power twistlocks used. I've even seen regular two prong 110V extension cords used but many unfortunate accidents with those cooking speaker cabs x( .

Back before there was any sort of standards for speaker connectors, people used whatever they could. Banana plugs, 1/4", XLRs, etc. For higher powered applications, some companies used multi-pole NEMA twist lock AC connectors which is now of violation of the National Electric Code since it would be possible to accidentally plug an AC source into your speakers or amp rack's speaker outputs ;) The Canon "EP" connectors were the first higher current connector which was like a giant XLR connector to be standardized for speaker use by EAW back in the late 80s. They go up to 8 pins for a 4-way box. That what my rig uses. I'll eventually swap them out for Speakons because the EPs don't hold up as well. Then the Speakons came out from Neutrik and those became industry standard. Still, some companies use a more proprietary Socopex multi-pin connector for combining multiple wires to create thicker wire gauges for longer cable runs and higher box counts for some of those big line arrays (like the new L'Acoustics K1 systems).
