Can someone (maybe the author) please elaborate on this section of the wiki article:
Locating the Group of B1s
Where to locate the group: If the group of B1s is far from its L1, the lows will come from one place and the highs from another and this is harder for everyone to hear clearly. More than about 5 feet (1.3 m) of separation is probably beginning to compromise your spatial quality. It's best if you can keep the B1s adjacent to or within a foot (30 cm) of the PS1. Since our preferred arrangements are stacks of 2 or 4 B1s, we also like to aim those stacks sideways and place them against the rear wall if we can, because this minimizes unwanted array effects with the first reflections.
The last sentence seems to indicate that the optimal orientation for the output of the B1 stacks is going to be at a right angle to the output of the cylindrical arrays.
Did I read this correctly? Is this an accepted fact? Why is this the case?
If true - it is litterally going to blow the brains of my rhythm section to shreads.
We pulled our quad stack apart last night and did two stacks of two - in an attmept to make the bass sound less mushy out front. That seemed to be a smart move on our part. We actually put the double stacks on opposite sides of the L1 M1 - so we may try putting them next to each other next time.
Needless to say - this is why I am poking around in the wiki article.
