hi jbell
that idea is covered in dave rat youtube video, live sound subwoofer configuration part 2.
dave shows us that if using virtual arc setup, by delaying outer stack consecutively, will sacrifice sound quality, less thump, slower low end attack.

Jbell I've done some figuring and come up with something that looks promising. I have some more refining to do to make it as accurate as possible and maybe get it into an easy to use formula, so bear with me

Interesting discussion regarding widening horizontal coverage when adding delay to outer pair of a stack of four speakers horizontally.

I wonder if the stereo image could be widened even further if stacking the speakers in an inverted arc in accordance to picture #21 in Rogs paper, combined with delaying the outer pair of speakers?


The difference at 100 hz is 3.5 dB more horizontal spl with the inverted arc compared to a straight stack without delay.

Sorry for necromancy.. ��
