| Re: Wierd Null
Before looking at your wierd null at 140hz, I would recommend you to check why you are measuring SPL over 104dB over most of your frequency range.
Did you perform the calibration correctly or are you simply playing too loud?
When it comes to your null, could it be standing waves? Check out your room modes and try to mode you sub around to see if you can remove this null.
