Not quite in the way it is thought of with the original LEDE designs. RFZ rooms will often have some kind of diffuse termination of the ISD gap, but not a Haas Kicker in the original sense. Those were too strong, and early on, not nearly diffuse enough. These days a more diffuse and less conspicuous termination is generally preferred.
By the way Jens, the diffusers look great! Can't wait to check 'em out when they're available. Could you tell us a bit about the measurement setup and technique?
