Not new to DIY, but still a novice

Currently have 5.1 set-up using Dayton 8", Vifa 3" dome and RT Ribbon as the mains. Center channel is a MTM, surrounds are again PE drivers. Subs are 2 10" JBL's. None of them are "voice matched". Electronics are a Yahama 7.1 Rec., Adcom200 WPC for the subs. I'd like to build something smaller (6.5" ??) that is very efficient. Thought of using Eminence 6.5" and Morel CAT378 horn loaded dome. Sensitivity would come in around 93-95 db @1 watt for dynamic range. Don't like horns....
Any ideas?

I would pose the question down in mission possible.
