John: Due to the fact you are writing something for a patent. I'd be sure that air=liquid. It is indeed a fluid, not a liquid.  This could possibly cause a problem with the patent(s). An attorney would be a good person to talk to if you're getting ready to set the world on fire and are investing significant money.  Good luck on that too.

You are 100% correct and if I hadn't forgotten to take my Gingko Biloba this morning I would have not made that mistake. (Shades of Tyson's signature)

It is a "Fluid" not a "liquid".

My Bad!  (I always wanted to say that, but now never again )

Just realized today I've been listening to my system with inverted phase for the last six weeks.  The JRDG 302/4 has its XLR inputs wired with pin3 hot, unlike just about everything else (including my dCs Elgar Plus) which has pin2 hot.  I saw "non-inverting" in the owner manual and never bothered to look at the pin assignment.

 

So I've inverted phase on the Elgar Plus and everything sounds even better

 

Thanks to Horsehead for pointing this out to me

Brian on "spikes"

Spikes both couple and decouple the cabinet/speaker output from the floor.
Bass wavelengths are quite long and, below about 200Hz, boundary dependent. Without a surface to travel along they dissipate somewhat rapidly. A woofer would ideally be as close to a boundary (floor) or multiple boundaries (side and back walls, and even ceiling) as possible, or at least a constant distance from them. By elevating a cabinet from the floor with spikes, you reduce the propagation efficiency of bass wavelengths. So, you decouple bass from the room, even if ever so slightly. The effect is quite audible.
Spikes couple cabinet output to the floor, turning it into a transmission medium. Soundwaves travel through many solids much more rapidly than through the air. Instead of "moving the floor", cabinet output is transmitted to the listener ahead of the music, through the floor (made usually a good carrier of sound like wood or stone). This is why I'm no fan of spikes, and the Sunfire people aren't either.

Since spikes do two things I don't like--diminish bass propagation, and transmit or even amplify spurious cabinet talk--I never recommend their use.

As Sunfire recommends, rubber or other absorbent materials can be used as feet for speakers or subs.
