Its like when people say boomy I am thinking do you mean if 29hz is playing and you walk around the room and its louder in some places and quiter in others and 40hz is louder hear but quiter here. How is that a bad thing it would be no different if you could just turn it up to whatever volume you want. I have looked up boomy and all I find is causes a peak at a certain frequecny again has is this a bad thing sure it makes it harder for a flat frequency response but it in itself is not a bad thing like a bad sound but you always hear people say car bass is boomy so I have yet to hear this explained. Also on a car audio forum a guy there told me that there is no such thing as speakers being good for certain kinds of music and I agreed with him that is up to the band performers whatever, in my opinion is a somewhat delusional to think this and a misconception. But I have plenty of life left maybe someone will prove to me otherwise.
OF course understanding the fundamentals helps understanding of the more advanced issues. THe things build on top of each other, just like math.
Boomy I generally take to mean that some frequencies are too loud - - probably a few specific frequencies in the midbass region of say 40 to 80 Hz so that when a bass player plays a scale, and he's playing each note eqully loudly, some notes jump out as being much louder.
Variance from location to location is a different phenomenon, although it can contribute to boomy bass at specific locations. It occurs in essentially every room because of the fundamental fact that sound waves bounce off the walls and recombine within the room. Depending on the frequency, and the location of the sub, and your location in the room, some frequencies will add together because it happens that the peak of the original sound and a reflected wave are combining at that location. In other words, the waves are in phase with each other. At other frequencies, the exact opposite may be true- - if the waves are 180 degrees out of phase with each other, one will be at a peak while the other is at a trough. So if it's an 85 dB tone, the +85 dB part of the wave combines with the -85 dB part of the reflected wave to add up to zero.
This does not typically occur in cars at subwoofer frequencies because the car is too small for a bass wave to bounce and be significantly out of phase. In a car what happens in the bass is pasically the whole cabin gets pressurized and depressurized simulteneously, as I understand it, so there's technically not a wave at all.
