PA speaker w/Eminence drivers


Hi, I'm working on building a pair of 2-way PA speakers for my mom for mobile karaoke use. My dad might also use them for local band performances. Basically, they need to be fairly cost effective and full range, since there will be no sub. I want something with some impact too (I hope I'm not asking too much). I was thinking a 12" 2 way with a 1" compression driver would work well, but I have no experience with pro speakers. Will a single 12" in a ported box provide enough impact? I would like to keep it under 3 cu ft if possible. If anyone has seen the prices on Eminence at www.partsexpress.com, you can see why I'm asking about using Eminence drivers. I was thinking a Delta 12LF with a PSD2002 or the Selenium 1" compression driver thats $50 (can't remember the name now). Thanks in advance for any suggestions and please feel free to rip apart my plan if it won't work!
