Yes, there is a bit of that, in that the CVX lacks a low filter, which was
engaged on the ME-62. I'll have to redo the test without the roll-off on
the ME-62. There is also the phenomenon of treble attenuation - low freq.
sounds travel further and maintain the energy better than higher freqs. A
parabola adjusts for this attenuation to a greater extent than the CVX,
apparently, by gathering a larger sample and focusing it on the capsule.
The CVX's amplification can only act on the sound that falls between its
two plates - an area much smaller than that of most parabolas.
Any word on this, Simon?
