Hi Mike,

Great link on Lenard Audio. Thank you very much.

Great link - I have seen it before but forgot what it was called. Love the first quote I saw about Line Arrays - "Line-source systems create a deviation in the character (for the use of a better word) of the sound. Line-source systems were rejected for cinemas (in the 50s) for this reason."
And the second " Many old 60s - 70s roadie sound engineers believed the lens directed sound downward to the audience sitting in the front row. The lens was commonly referred to as a waterfall effect speaker."
It seems to be a case of collective amnesia in the SR world! What happens next - forget about the Holocaust?
