Speaking of passive coaxial speakers, maybe this information is gonna be of interest for some of you. L-Acoustics has a new range of 5inches and 8inches products (5XT and X8). The company is reknown for putting a lot of attention on the polar response / off-axis behavior.
I have heard the former 8 inches model (8XT) on a couple of HOA rigs, sounded great.
