Numbers don't tell you how a speaker sounds. I recommend the QSC K10 or 
K10.2 as they sound good, both at low and high levels. I imagine the 
CP12 would sound OK too. Bear in mind that the published power rating 
for these is peak power, not the standard RMS so 1,000W or 2,000W is not 
actually that much. I have 2,000W peak power in my car!
