Re: speaker cabinet impedance
I've just looked at the Peavey manual on line and I can understand your confusion, bad manual!!
I think from the reply you had that when you plug an extension speaker in the back (in parallel) the jack socket switches the amp from 16 to 8 ohm operation, hence you'll need a 16 ohm extension cab.
That last option you mention is what I effectively do.
I have a Laney head and I wanted a couple of 2x12 cabs, but most were too big to go into the back of my car easily. I chose the Marshall Valvestate cabs which are small enough but come wired for stereo. I changed the wiring so that the two 8 ohm speakers were in series giving me 16 ohm cabs.
The head has different outputs for different impedances, so at practices I use one cab in the 16 ohm socket, and at gig use both cabs as a combined 8 ohm load!
I guess you *could* always get a Peavey extension cab?
But if I were you I'd probably by a nice Celestion speaker (which are available in 8 or 16 ohm versions) and make a cab for it to go in. The woodworking is pretty easy as unlike bass speakers you don't really have to worry about the construction other than it being a rigid box.
