Hi!
I have a pair of Carvin 4x12 guitar cabinets that each run 4-16ohm Celestions. These are very early '70's vintage, with exceptional versions of Celestions, and heavy, sealed cabinets. They have a fantastic sound when wired to 4 ohms and used in stereo, and a mean heavy crunch at 8ohm (sum/2 16ohm cabs) in bridged mono. However, it's a bit time consuming stopping to rewire the cabinets especially during a gig...ha ha.
Can someone lay down the skinny on how to wire these so that I could switch each cabinet from 16ohm, to 8ohm, or to 4ohm? I had a Randall 2x12 cabinet that had a switch that allowed one to change from 8ohm to 4 ohm at will, so I know it's possible, just beyond my technical level to figure out.
If possible, I'd like to have the capability to select (via a switch/switches on each) each cabinets ohm rating at my discretion depending on how I want to configure (ie: both cabinets running in stereo, split mono, bridged mono, or using only 1 cabinet). It doesn't matter to me how many switches it would take, although, if possible, I'd prefer to avoid having to switch from one speaker jack to another (on the cabinets... obviously this would be required if running both in series).
If it's possible, it would also be cool to be able to flip a switch and split a single cabinet from 4x12's, to 2 2x12's and use a single cabinet in stereo. Of course that would require an additional speaker jack for connection to the amp.
If someone could help me out with this I would appreciate it immensely. A simple wiring diagram would greatly aid in the chance of success on my part as well. Any input would be great. Thanks very much in advance.
Regards,
Mike
