Glad to help. With your set-up, if you try to put a loud low frequency signal
well outside the loudspeaker array, you will notice that your speakers and/or
amplifiers will have melted. To the extent that sin(theta_A) = theta_A
(small-angle approximation), for every halving that you reduce the loudspeaker
spacing, there is a doubling of low frequency amplitude requirements for images
at 90 degrees. There is a cure for this--let me know if this situation bites
you. (Also, for every halving of loudspeaker angle, there is an octave added to
the frequency range over which the widening works.)
Hi Jerry,
I'm not sure I follow you here.
I'm not using ITD, only amplitude (a sum of in-phase and 180-degree
phase signals). I don't see how this can impact the frequency response.
Can you give me a clue?
Thanks
Ross.
