Hi there, I am having trouble with my subwoofer output above 80hz. The spl level drops very much so above 80hz. I didn’t have this problem with Denon & same subwoofer (Rel HT 1205). It is as if the Av receiver is applying a cut off beyond 80hz. I even raised high frequency to max but still nothing. Any idea whats going on. The explosions and bombs going off are all good, it’s just the higher frequencies that are suffering like human voices etc.
It is hard to tell from the pdf file as they don't really represent well what's happening at your mlp. Can you post some REW graphs? One thing you can try quickly is to increase the center frequency for room gain and set the room gain to maximum, that's just to see if that would change anything to >80 Hz, just to help troubleshooting.
