So I’ve set up my dual PB16 subs, I ran Audyssey on my x4500h and when level matching the the subs I had to set my front left sub to -18db and my front right sub to -21db, which gave me trims in my AVR of -11 and -10.5 for my subs. My subs are pretty much equidistant from my mlp, that is where I am getting the best response. So my question is if it is ok to have different gains on my subs even though they are identical? Or should I just turn up or down the gain to have the them matched?
Even though the subs may be equidistant from the MLP, the way that they are interacting with the room (at their specific locations in the room), is not identical. That's why the gains are different. Audyssey has set your subs to play at the same volume at the MLP, which is exactly what you want.
Any adjustments that you ever make to either the sub gains, or to the trim levels in the AVR, should be symmetrical from your current baseline gain settings of -18/-21, and from your trim settings of -11/-10.5. Just adjust both subs equally for any increases or decreases in volume.
