B1 Bass Module

Keep the B1s Together
If you have more than one B1 playing the same sound source (instrument), keep the B1s together. You should get as much as 3 dB more than if you have them separated. This is due to acoustic coupling. This also avoids creating nulls.
You can stack them or have them side-by-side but you want to keep them together.
Check the Cables
You may want to double check your Blue B1 cables. See B1 Cable Connections
Rotate the Logos
You can rotate the Bose logo so it is parallel to the floor even if you have turned the B1 on its side. Chuck-at-Bose said, "... Maybe it's my kung fu grip, but I've had good luck with carefully pinching the logo and pulling at these points, then rotating 90 degrees:"
How Low does the B1 Go?
The short answer: 40 Hz. But about instruments that go lower than that.
A much better answer comes from Hilmar-at-Bose in Bass Frequencies
Bass Outdoors
Chris-at-Bose describes what happens to your bass when you move your System outside in Bass Outdoors
Port Orientation
"Theoretically, port-side-up may give a tiny bit better aligned floor reflection but in practice, the difference is so small that it isn't worth bothering with. However, I would still advise when you stack multiple B1s keep them all in the same orientation." See Hilmar's comments about this in context
When I read this, I had to go and look very closely to find the port. It's easier to figure out that when the B1 is on it's side, port side up is same as (on the back) connection panel down.
Longer cables for B1s
Unfortunately, the Speakon connector comes in three different flavors, NL2 (2-pins), NL4 (4 pins), and NL8 (4-pins). Most salespeople are not aware of the differences. The Bose B1 requires a NL4 connector with all 4 pins connected (that's why we call it 4-wire cable).
A good source for these cables is

If you call Mark and tell him you want the cable for the Bose B1, you will get on that is made to our specifications. You can also any custom length cable at a very reasonable price.
