Combo elec/acoustic amp - speaker thoughts?

[TonyR]

I'm considering a homebrew combo amp that would allow me to use both my acoustic and electric through it, for easy on-stageness. I have a Gallien Krueger 112LC amp and cabinet (no speaker though) that someone gave me; the normal channel sounds good enough for acoustic. My electric amp is a cigar box-sized, modified 60's organ amp - I can fit this into the GK cabinet (it's currently in a Princeton cabinet). Idea is that I plug my acoustic into the GK input, and my Tele into the electric amp input.

Thing to figure out is speakers. I am considering 2x8's, which I think would work well with acoustic and will be like a little dual Champ arrangement.

My question is around typical speakers for acoustic amps - how do they differ than typical electric speakers - is it mostly a power rating thing, or are they actually designed and constructed differently?

I probably will want to optimize this for the Tele, so probably will end up with more 'electric' speakers - I don't need perfect crystalline acoustic sound. But I'm curious how different the usual acoustic speakers are from electric speakers.

Thoughts?

My 2 cents is that speakers in acoustic amps are like hifi speakers: they try to be as neutral as possible and not colour the tone. Speakers for electric guitar tend to colour the tone more and to have a mid-range hump.

Edit: what musical styles are you going for, especially with the Tele -- clean/country?

Acoustic amps typically have tweeters and as Big Daddy said they try to be neutral. The acoustic guitar already makes a desirable sound that you are trying to amplify. Electric guitars without an amp sound very thin. Almost a useless tone by themselves. The amp then becomes an indespensible part of the sound. Tube amps, although ancient technology, are still favored by guitarists precisely because they are imperfect in a way that produces a rich, ballsy tone with the electric. One way around this is to use a solid state amp, full range speakers, with a digital pre-amp. They are designed to make full range amp/speakers sound like a tube amp but they will also allow bypassing the amp modelling which would work well for the acoustic. You could even add chorus and reverb to the acoustic as well which would sound nice.

One of the best acoustic guitar sounds I ever got was with a SF Twin Reverb.
Eminence makes an 8" with a coaxial tweeter, but I would go for 2x10"s or a single 12" JBL or equivalent Weber with aluminum dustcap. Plenty of high end response and also great electric tone.
