Re: Flex Your PCD Mettle:
One is normalized, and one not. The one not is how it plays, dispersion-wise, as built. 3D3A Lab wants to minimize lateral reflections, which mess with their crosstalk-cancellation algorithm. Thus, this is a notably narrow-directivity speaker.
Toole suggests that wider dispersion is better suited for surrounds - the more reflections, the better. You want surround, the next one up is 90° x 90°. We can go as wide as 120° x 60° with single JBL PT waveguides, but beyond that, we have to double them up for 180° or wider....
