It seems like second guessing the design engineers is a common thread starter.
Yesterday, I was playing with my HPR181 and 152's, trying to use SMAART to look closer at the crossover region. The HPR's have a built in crossover that is at 100 hz.
I started with the boxes stacked with the front edges aligned. It seemed my best measurement was at 1m on axis with the mic centered between the two boxes. I also tried ground plane at 1m and 2 m. I was getting consistent results with all three positiona. I finally determined a delay of 1.5 ms.
Then I switched over to the pole mount and determined the delay needed. You guessed it: 0 ms.
Lesson learned: If you are going to use a system that is designed to work together, it is probably best to trust the designers.
This is probably biased because I have been listening to these boxes with minimum processing for two years, but I didn't find any eq changes for the top that I thought sounded better than just leaving the processing flat.
