Re: Flares for PSD2002 in Theater Four Pi.
I prefer radial horns to pure CD horns. What I like is constant directivity in the horizontal plane and collapsing directivity in the vertical plane. This improves uniformity of the reverberent field because the energy distribution around the room is nea...

Re: Pi horn design philosophies
There are a handful of horn features that determine the way a horn behaves. This is a list of a few of them, the main ones:1. Flare shape sets the acoustic loading as a function of frequency. Some shapes (exponential, for example) load low frequencies b...

Pi horn design philosophies
Pi Speakers are best described as high-efficiency, controlled directivity loudspeakers. They've always used high-efficiency drivers like those from Eminence and JBL. They evolved from my early designs concentrating mostly on flat amplitude response to ha...
