are there curves available for the measured performance of these drivers on and off-axis? I could not find them in their online specs.
I was just about to link to those same measurements! PHL are not famed for publishing measurements. Their market is mostly OEM so I guess the manufacturers get samples and take their own measurements??
They sell an awful lot of drivers to some major pro audio speaker manufacturers!
