The grouping of different subs together sounds like a typical Yorkville courtesy feature. A close enough for Jazz sort of thing. I reckon their theory is that if you're knowledgeable enough to spot the flaws in the group delay you will be knowledgeable enough to calculate your own tops delay using an external processor.
They probably figure, a few different generic global delays might be better than nothing at all. and maybe better than too many choices. After all, it would seem that a large part of their market is rentals, by band noobs, DJ's and other folks that might not spend their spare time reading tech specs. Not that I've ever done that!

So what's it all mean basil?
It means that you should contact Yorkville, and ask for a clarification . They're usually very quick at getting back to you, typically within 24 hours, sometimes, even on weekends. I've had Mike Holman, from Yorkvilles' Canada customer service, email me on a Sunday.
According to the manual I linked to earlier, there is no difference between the LS1004 and the LS801P, as far as time-alignment is concerned,,, which doesn't mean they'll sound the same. The LS801P however, is very flexible in how you can "shape" the sound. The lo-pass filter is sweepable between 90-150Hz, and you also have a sweepable "shape" control, which allows you to completely change the "tone" of the sub. You can dial it in from a very LF sound, to a very tight/ punchy (and very loud) tone. Theoretically, this would allow some flexibility in matching the tone of the two subs,,, more so than you would with mis-matched subs that don't have that capability.

Consider dumping the dual 18 cabinet, and getting another pair of the ls800's.
It is pretty much a rule of thumb not to mix and match different types of subs.
Having four ls800's makes more sense all the way around.
Probably not what you want to hear.

Would splitting the frequencys with a crossover so that each set of subs handle the freq's they are strongest at get the results he is looking for, or would the phase issue still be there? God this place gets me thinking.
