Cannon EP-4-14?

[Executioner213]

If anyone know what I'm talking about here...This is an old style speaker connection that a friend of mine has on some OLD Peavey HDH stacks. We are trying to figure out if these can be upgraded to speakon? I found some jackplates on Redco that look like they would retrofit...BUT, will it be able to be swapped with those new connectors or will it be a colossal goat fuck?

The best pic I could find of these on the net is on the manual for one of these speakers. http://www.peavey.com/assets/literature/manuals/HDH-4.pdf

I'm pretty sure it can be done. Your gonna be sending the same signal, but just with different connectors.
Here's a sweet wiring guide for Speakon: http://www.crownaudio.com/pdf/amps/126986.pdf

Speakon connectors are made in two, four and eight-pole configurations. The two-pole line connector will mate with the four-pole panel connector, connecting to +1 and −1; but the reverse combination will not work. The eight-pole connector is physically larger to accommodate the extra poles. The four-pole connector is the most common at least from the availability of ready-made leads, as it allows for things like Bi-amping (two of the four connections for the higher-frequency signal, with the other two for the lower-frequency signal) without two separate cables. Similarly, the eight-pole connector could be used for Tri-amping (two poles each for low, mid and high frequencies with two unused).
