Hi Geno,
There are 1" tall fiber cones under the front of the baffles in this photo.
Truthfully, I don't hear any difference in my system with them or without them.
My listening seat is 7 to 8 feet from the plane of the speakers.
I know that some Betsy baffle owners have reported good results with tilting the baffles back slightly, while others are hearing the same thing that I am.
I don't recommend creating a wide gap between the base of the baffle and the floor because some of the "coupling" could be lost which would affect the tonal balance ..... however, your mileage may vary.
It's possible that the effect is either room dependent or dependent on the distance between the baffles and the listening seat ..... just guessing .....

Best wishes,
Randy
