What you said is all so true.
In this world, there are all types of music.
I reproduce songs that cover almost all of the audio spectrum.
The reason I make some songs with such infrasonics is because not many people can reproduce these loudly without damaging there systems.
Thats the whole idea of mines. When I see (or hear in person) a sound system that reproduces these frequencies loudly with hardly any effort, I just simply say: "You are the king of bass".
Oh..my 42" tube is sealed. No port. Ports make too much noise and cancel out infrasonics. Unless the tube is as big as my house to get tuned to 10hz.
