=== 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 five feet 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 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. But we don't hesitate to aim the stacks forward when the best appearance is more important. In this case, we keep the B1s as close to the back wall as the connectors allow, but being careful not to stress the cables by bending them too sharply against the wall. It's okay to raise the B1s on short risers if you like, but I don't know of any reason why this would always sound better or worse, just different. Floors and walls are not perfect reflectors of bass, but I have no different recommendations to make due to this source of variation.

Although we prefer to keep the B1s as close to the rear wall as we can, there are times when this is just not an option. In such cases, we try to get 7 feet or more from a rear wall as a second choice because, in the 2-7 foot range, the reflection from the rear wall tends to reduce some of the bass frequency range in the audience (an interference effect). Sometimes we have no choice but to place B1s in that 2-7 foot range and we just live with the minor reduction in bass, perhaps compensating with a bass tone control boost.

Other variations: It's okay to raise the B1s on short risers if you like, but I don't know of any reason why this would always sound better or worse, just different.
