Last time I went shopping I brought with a simple 30% volume pink noise track. You can hear a bit of the tonal differences between loudspeakers when you play the pink track. Pink noise is wide enough that you can get close enough when leveling loudspeakers with an SPL meter. I didn't think to bring a tripod so just moving my hand around a tiny bit would vary the signal by +-0.3db. I figured I would get close enough to 80db to consider all the speakers I was listening to "leveled" -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=93111 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
