Need speakers that can rock with just one watt? You found da place.

RE: Why do line arrays using directional speakers require shorter lines for similar near field performance?

Hi Claude
I had the camera at 100 meters from the source (and well past the usable distance for large line arrays) which makes a sound level measurement -40dB re 1 meter (easy to keep track of).

That recording was hitting peaks approaching 90dB fast and avg more like 80dB slow but it hit 105dB A slow at the point the limiters start to get tickled using the stadium type test noise signal. Good catch, the knee in the lf response is -3 @55Hz.
Yeah Boz has some great recordings, I like to use the same material I would use to evaluate speakers in my living room although others play more classic, less subtle PA test program like AC/DC or EDM which I find enjoyable in smaller quantities.
