I created a small frequency test file contain short (10 second) bands of sine wave. The first being at 4096 Hz, then 2048 Hz, and on down. I was able to hear the 64 Hz band but nothing lower. At first you think "oh, the speakers just can't produce 32 Hz." But when I feed line out into my cassette recorder the last band showing any activity on the VU meters is the 64 Hz band. There is no signal coming out of the Mac below that. Is there a band pass filter in the Mac's audio system?

Well, now that I have removed my head from that place where the sun doesn't shine, you all can please forget that I ever asked the question. The signal was there but just to low to trigger the VU meters.
