I doubt 1/4" connectors are quite as hardy.So I looked it up. Back in 1978, 3 pin ITT-Cannon XLR connectors were rated at 15 Amps per contact and #14 wire. 4 pin connectors at 10 Amps. 5 pin connectors at 7.5 Amps.

Right. They were used for telephone commutators.
You need a little air to get in the cabinet to counteract air pressure changes outside.
Even if its a tiny hole.

I don't want line level or power, I want jacks for power amp output to the speakers. In the instrument world, that's 1/4 " jacks.If the amp is not inside the box, why do you need to bring line level into it?
Or are you planning on using line level connectors for power?

The pins may be #14 but there's no way I could get #14 wire to connect to most XLR plugs or jacks.
XLR and 1/4" jacks are both really not great choices for speakers, but 1/4 is the standard for semi-pro instrument amps and PA, whereas XLR are almost always for balanced mic or line. 35 years in the business and I've never seen a commercial XLR cable that used heavy wire, just #22 twisted pair under a shield and drain at the best, not intended for high-current speakers. And the requirement is 2-conductor, not 3. Then again 1/4" shorts momentarily during insertion and removal unless you always unplug the amp end first. The more we discuss it the more I'm convinced the Neutrik Speak-On is all I need or want.
Say that again? Isn't that power?I don't want line level or power, I want jacks for power amp output to the speakers.
While the need to attach 14AWG wires to XLR connectors is probably long past, I just check the connectors in my spares box and 14AWG wire easily fits in all the contacts.
Quite a few a very pro companies back in the day used XLR connectors on their cabinets, Turbosound and Martin come to mind quick. Before the Neutrik Speakon many people and companies used twist lock power connectors for speaker connections. The Cannon EP connector was also popular for quite a while, with 6 conductors you could make a single connection to three way tri-amped box. Today the speakon NL4 and NL8 rule the market.
Well, I'm done. I wish I'd just left the 1/4" connectors off. I used Neutrik brank 1/4" locking jacks, with the button to remove the 1/4" TS or TRS plug. I also mounted Neutrik NL4. I wired the 1/4" with one wire to each driver, and all 4 driver terminals are connected to the Neutrik. So I wired Neutric NL4 "plugs" with internal jumpers that just wire the drivers in parallel or series for the 1/4" jack to use. And of course the Neurtik NL4 can be wired and used in any way since they have all dirver terminals wired to them.
Next question:
What's the standard for the 1/4" jack. With + on the tip, should the cone move in or out?
What's the standard for wiring the NL4 for two drivers (mostly interested in polarity)? Wire one driver to which pins, other to which, and which way should the cone move with + on which...

Positive on + should make the cone move out. NL4s are wired with the bass on 1 and the treble on 2, so if a NL2 is plugged in by mistake the tweeter doesn't get driven full range.
I don't understand what you are saying. Postive on positive? + on +? Huh?
means nothing to me. Bass driver on only one terminal? Treble driver on only one terminal? You lost me.
I understand the NL2/NL4 concerns, but I don't really know how to wire either.
Saw it online somewhere though...
On the NL4 the bass is on TWO terminals, and the treble on 2 others...which of the 4 terminals are paired for one driver, which are paired for the other driver? And then which of each pair is + for cone to move out?
For the 1/4" is the tip or the sleeve positive for the come to move out?

OK I think my confusion woth the NL4 is how the pins are numbered. I can't see mine anymore (mounted and shrinwrap) so I'll buy a plug and use a meter to see which color wire is which. I should have written it down before covering. So if the NL4 are +1/-1/+2/-2 I'd expected just 1/2/3/4.
For the 1/4 inch plugs another thread post said + on the TIP moves cone forward so I'm OK there now.
