Have been on a somewhat confusing thread on AudioKarma about lack of bass (and a fixation on visible woofer movement) in a fellow's home when he moves speakers from a smaller room upstairs to a somewhat larger but much less sealed living room downstairs. I've offered many possibilities about why this may occur but he seems to have covered most of the issues except room treatment, and an adjoining room with 20 pairs of speakers for comparison and playing around purposes (with apparently the other wall to also be covered.
Any thoughts on why this guy can't get the bass response he want? And why apparent visible woofer excursion (not that it always contributes meaningfully to bass response or the "SLAM" that he wants) is affected by moving speakers from room to room, or in the below comment, lifting from floor to on top of another speaker?

"I do have several decent EQ's but at this point they've not been set up here. On the A-700 amp, I'm using the tone bypass button, and did when I tried it in the living room as well. The SX1080 doesn't have that option but it does have a loudness lever which is always off. I've already seen the obvious change in woofer excursion on the Mach One's and JBL CF150's by simply raising and lowering the speakers in the living room, what I don't get is why the change. I'm not touching the volume or other controls, I'm simply picking the speaker up and placing it atop the TZ-9 tower, (with a piece of shelf liner in between so as not to scratch either speaker). The change in woofer movement is obvious. The volume knob is usually at about 9 o'clock "
My head hurts a bit from trying to follow this guy's equipment obsession and lack of desire to simplify things from a troubleshooting aspect.
