... Anyway that concludes the integration setup for now, I hope it helps some of you get more out of your systems.
Once again, thanks for putting this awesome walkthrough together. If you don't mind, I have a few questions about measurement locations and the adjuments you made.
I'll start by asking what you meant when you wrote this:
"I could probably move the summation point forward a little to get things closer at each row but first..."
Just wondering how you can move the summation point forward or backward? In other words, what do you do to achieve this?
Next, I'll ask about the measurement locations and strategy.
Were all of the measurements that you used to in order to determine delay amount just the ones taken from the central location between the two rows of seating? I know you took multiple measurements at different locations, but which did you use to make your adjustments?
Also, when you then said that you would now check the front row and then the back row to see how close the match your other measurements, were you using one location on each row or instead, did you take measurements at each seat of a row and then average that out, and used the average to represent the row?
The same questions apply to the integration with the Mains. Did you do the integration just using the central position between the rows or did you use an MLP for the integration?
I'm only working with 2 subs and in order to avoid a 15db difference between the two rows (in the lower frequencies when I had both subs upfront) I had to place one sub up front just to the right of the left Main speaker, and the second sub is almost mid-wall on the right side wall. So they are somewhat diagonal from each other.
With REW I'm limited to 30 measurements before it can't save any more measurements for that session. with two rows of seating and 5 total seats, I seem to be running out of space quickly when I start measuring each seat. However, the difference in delay to (time align the subs) at the Front Left seat vs the Rear Right seat seems to be about 5ms. So I'm torn with having to either split the difference or favor one seat. So I'm wondering how you decided on which location and settings to use in order to maximize the gains across all seats?
