Be careful here my friend....Too much front wall damping will kill the life of your sound, having a little "bounce" or "Liveliness" is a good thing! Lacking clarity in the system is from the bass crossed over to high so as to muck up the main speakers OR your speakers need to be turned or moved just a little to help kill the bad resonance, try checking your settings and go lightly on more room treatments.
