[QUOTE="Immacomputer, post: 4903970, member: 570419"] Which makes that frequency audible as long as there is significant pressure to break the threshold of detection or not. I can detect a 7hz note played in my car with this enclosure much easier than I can with the same sub in a sealed enclosure with more power in the same car and position. When I say audible, I mean that there is significant pressure to cause my brain to detect a very low frequency. It doesn't matter what part of my body is reporting the frequency, just that it is detected. It does not matter if my hearing starts to roll off around 25hz (which I already mentioned) because I can still detect the signals much lower than that and detection is what it's all about. This also applies to NDMstang65's post as well. And yes, my system has a -3dB points at 15hz and 70hz with NO EQ whatsoever. This was measured response too, not just numbers pulled out of my ***. From 24-65, I am flat within .1dB. At 22hz I have a 4dB peak and it slowly rolls off down to 15hz and I didn't measure any lower than that due to not having the test tones at the time. [/QUOTE]
