Glad to hear it.
Try moving the speaks 6" or so closer to the wall as a test if you haven't already and see if that helps.
Also, if you haven't already, make sure you have both speaks connected to amp in phase, ie + to + and - to - on both. Bass is compromised when speaks are mistakenly hooked up out of phase.
Meanwhile, I've loosely plugged the ports on my Walsh 2 Series 3 in my 12X 12 sun-room with cathedral ceiling and moved one out from the corner in order to lower the bass level which I thought was just a tad too much prior.
