Elevating subwoofer about two feet off the floor

hey ejr1953,

Thanks for the tip about Room EQ Wizard.

i have 2 JL subs. they sounded far more integrated w the mains (magicos) when i elevated them 3" off the floor by way of maple stand.

improved further when i ditched their stock soft feet for cone footers. 

i leave it to armchair theorists to disagree w/ my experience. floor boundaries good for more bass, but less integration w/ mains.

I have my 2 JLs on Auralex subdude stands. They are inexpensive and work very well. Bass became more defined and propulsive.

I believe the Harmon-Kardon paper on bass reproduction, the basis for the concept of subwoofer "swarms", recommends locating subs at varying distances from the floor, thinking of the room in terms of a 3-dimensional volume, not a 2-dimensional floor.
