I was recently at a friend's house auditioning his Outlaw Audio LFM-1. This unit is rated flat to 25Hz. We listened to a variety of music and also to test tones.
My friend had the subwoofer positioned behind and to the right of us. I believe he had it crossed-over at 80, or perhaps 100Hz. When he turned the volume up on the sub (while playing music), I could definitely percieve an increase in sound energy to my right and behind, not with pinpoint accuracy, but generally. Playing test tones was interesting. Unless they've heard a test disc, I don't think most people realize what a jarring experience it is to listen to a pure 25Hz tone. It's actually quite uncomfortable, physically. Furthermore, listening to the range of higher-frequency test tones revealed that I could change the apparent location of the source of sound by simply slightly rotating my head or moving forward or backward a few inches. I would offer the suggestion that any directionality one percieves from really low tones, like lowest notes on a pipe organ are due to the harmonics that are are accompaning it (and making it more palatable). I think that extended listening to a pure 16Hz tone without the accompaning harmonics would probably melt your brain, or at least drive you batty. -- jonheal Jon Heal says: Have a nice day! http://www.theheals.org/ ------------------------------------------------------------------------ jonheal's Profile: http://forums.slimdevices.com/member.php?userid=2133 View this thread: http://forums.slimdevices.com/showthread.php?t=20197 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
