had fun with this bass test. At 10hz a little hum, barely. At 15hz about the same.
At 20hz slightly louder. At 25hz, whooeee, everything in the room shook a little. What fun.
very interesting to hear the different bass sounds in 5hz increments going up.
This also shows how much low midrange is in the 70-100hz range.
popgadget, crank up one of your professional speakers please with this video some time.
I'm curious how low it goes, though that was never its reason to be.
I need to go back and test system again, and throw the phase switch to see if I can tell the difference.
if I found a high frequency sweep test I would probably be depressed over how little I hear any more.
