Good info!
And the SpeakOns are just screwed on, which makes the wires easy to cut to length.
Another thing, it's bloody hard to find black-jacketed large-gauge twister-pair speaker wire. So these would be a good source not only for the SpeakOns, but also for the wire. (And even if one tosses the ends... ~60 cents a foot for jacketed 12/2 is only expensive in Monoprice-land.)
I'm curious what you mean by "need a jeweler's screwdriver..." though. I've never had any problem taking apart an ur-SpeakOn, or an SPX model.
Admittedly, my SpeakOn use has been exclusively in controlled temp/humidity homes. And the Neutrik made-in-Liechtenstein models, not the knockoffs that Monoprice has to be using at those prices.
