Agreed RE: speaker and listening chair replacement. That was how I got my bass response dialed in for all the better. It was boomy and sloppy before. My trick was to get my listening chair off of the back wall. With the chair out into the room somewhat it evened out the bass. I no longer had the suckout at 70-80hz and the boom at 40-50 and 120hz. Do not use cables as a tone control in this application.
You might also investigate spikes or brass cone footers for you speakers and especially source components! Again, the bass will improve!
