I have been told it is allways favoured to vertically align the individual woofers and drivers on a baffle.
As I understand this is to avoid lobing and getting the individual sources to match up better and improve imaging.

A speaker like the JBL S9900 follows this aproach, but the JBL Everest DD66000 or DD67000 doesn´t.
The Everest speakers only use one of their 15" woofers to run up high to the horn. So the center of the "midrange-woofer" isn´t vertically aligned with the center of the horn. It is offset by about 8".
I wonder how this affects the overal presentation?
Is this considered to be a major tradeoff in this speaker-layout or is the offset of such small amount that it doesn´t really affect the sound?

Best regards,
Olaf
