Re: Flown Subs, Ground Bounce, and People in 1/2 space IIRC, when the sub is directly on the ground, there is a very even ~6dB increase in the entire 180 degree half-sphere around it, since at the wavelengths we are dealing with I would think that even if the center of the driver were 8-12 inches off the ground it wouldn't have much of an effect. And when we started to move sub off the ground that is when it started to become uneven.Also as you take the sub off the ground, directly above would seem to be where you would see the most destructive interference, since that would be the place where the time difference between the direct and reflected wave from directly below the sub would be greatest.Take Care,Phil
