Maybe you should tell us again what you plan to do with this system, i.e. play at home, with a band, drummer etc. Use the setup for solo gigs, with vocals?
I bought a couple of real nice Roland kc 300's on ebay, 4 channels 12" and horn 100 good clean watts of power.
They cost me about 200 bucks apiece after you add shipping. I also bought a nice peavey 200p powered speaker 12" and a horn.about 400 watts of power, with shipping 225.
Go back and read your other speaker post about how to rate power in amp.
IMO Gemini has about the quality of Radio Shack.
You'd be better off with a used peavey or Roland.
