Do some of you manually set the PEQ's? (which is what I do)
Is it possible for BEQ on the input to interact oddly with either of these type of settings? I just went through a lot of hoops to smooth my lowest bass with my current configuration and I'm very fearful that this is the case particulary in the lowest bass frequencies.
I went through this video, and the so called 'sub aligning' is seems to be incorrect. This video is NOT how to time align subs. Here's the book
on how to time align subs. Page 26 and 27 are perfect examples.
Yes, I use the EQ function for each sub, that are time aligned to achieve a flatter/smoother/downward FR for each sub.
Then I scan the sum of the whole IE, all the subs, I make changes with the PEQ to level/smooth the FR across the room, and apply those on the output for individual subs and rescan, rinse and repeat.. Tedious, yes. it is, however, in the video.. he applies a 'peanut butter spread' method, and yes it can work, but, not the way I prefer. As I'd rather control the individual culprit of the problem frequency at the source sub, versus every sub not outputting that frequency to achieve the desired response.
I'm not sure on your last question though as far as the BEQ interacting oddly. I haven't notice anything, so I don't know I understand what you mean by that.
Now, I am not saying that the video FR response is not bad at the end, but I'd like to see it with properly aligned subs to make the virtual sub speaker more in sync with what the Audyssey or Dirac would expect with just a "single sub unit".
