    I'm no expert, and cannot base my thoughts on the video solely due to the fact my computer speakers suck. That being said, it would seem to me that ring radiator + waveguide = poo! I mean given the way the ring radiator tweeter emits sound, it would seem that a wave guide would diminish some of the tweeter's advantages, while at the same time "amplifying" other good parts to point of not good anymore....But what the hell do I know, it may sound good:o

    A waveguide will allow the tweeter make the driver more efficient, allow it to play deeper, but will create a dip at the top end. So more than additional padding will be needed to compensate.
