ULF listning habits
I know a true measure of DIY subs are less than 20hz frequencies, but while hitting 10hz and under is nice, honestly how often do people listen to them/ how long do they appear in movies and at what SPL? i.e. a passage of 5 seconds or something,
I would realize that 115 Reference level is a peak, but at a certain high level low frequencies cause structural damage (not always a bad thing in this crowd)
I am guessing that the damage is room dependent, but as a general rule of thumb, around what level would you say is dangerous for ULF?
