Best reasonable$ upgrade from spikes?
Good point Charlie. Wood frame and thus suffering from all the symptoms you describe. I can feel those particularly boomy bass notes through the soles of my feet. Think i'll try the foot test in my experiments.

Wow!! Thanks for all the feedback. I was hesitant ont he audiopoints for some reason but will definitely consider these after so much positive experiences. Anyone got a counter-word on Polycrystal speaker spikes? 
Integrated preout to subwoofer is the best
I had a sub at one point and when using interconnects it bypassed the hi-pass filter and wasn't recommended. Then again it was a rather inexpensive one.
