Yeah you're going to have to go with much more sensitive speakers, active speakers, or do serious bass management crossed over to powered subwoofer(s)! The last is a good quick try for your. Add a subwoofer, an AV pre/pro, do bass managment, and the dynamic range of your sysetm will go up temendously! It will take the strain off your speakers, and make the active powered sub do all the hard dyanmic work down low, were it counts the most!
I suggest this last as your first step when you are "ROCKIN".
