Pianoman, you have opened up the proverbial box of worms. You should get lots of suggestions: Barbetta, Motion Sound, EV, JBL, Boss, Yamaha, FTB, and on and on. Look back on the last 30 days of post and you will find plenty of talk about all types of speakers. Sounds like you might at least want something self-powered, but it really comes down to a few questions.

What do you want them for? Where will you be using them? How many do you want? How big/small do you want to go? What's your budget? SHALL I GO ON?

We all have our favorites and we'll all tell you the final decision has to be based on your needs, ears and pocketbook.
