@tmac1700, are you just looking for new speakers or do you want your rock, hiphop and techno tracks to sound better?
You mention boomy bass, that is normally a room acoustics issue, usually handled quite well with multiple subs, room treatments and possibly some parametric e.q. Most times when using subs it is works best to plug any ports in your main speakers.
Are there other issues that are bothering you, or is it just the boominess?
