L1 Cylindrical Radiator® loudspeaker

Lesson: Keep the audience in the column of sound
If you are on an elevated stage, remember that people above or below the Cylindrical Radiator™ will not be in the coverage area.
Hint: Tip the PowerStand by a few degrees from the back or the front by a few degrees. Easy ways to do this: Fold a B1 case and tuck it under the front or the back. If you have the logo bags with the wheels, then leaving the PowerStand in the case will naturally tip it down. I carry a couple of sheets of bubble pack packing material in the case and fold it to suit.

Lesson: Be careful how you insert the lower section. If you insert it upside down you may damage the connector in the PowerStand.

Lesson: If you notice a change in the propagation properties of the System, check that the sound is coming from both the top and bottom sections. If not, dissassemble and reassemble the L1 making sure that everything connects firmly.

Lesson: Slapback echo
If you are getting echos from the wall opposite the stage tip the PowerStand a little (1 or 2° should do it).

Lesson: Do not remove the Bayonet
The Bayonet should not be removed from the top section of the L1. It may be a stretch at first, but you can get the top portion of the L1 into the carrying bag.

Lesson: The Bayonet can be adjusted for easier mouting/dismounting with lower ceilings.
Newer L1 Cylindrical Radiator(r) loudspeakers have bayonets with three holes. With the upper L1 on a table or floor, you can easily unscrew the two Phillips-head screws from the Bayonet and reposition the Bayonet so that it does not protrude as much out from the upper L1. This gains you an extra inch of space when mounting/dismounting the upper L1 in places where the ceiling height is less than ideal. Contributed by Kyle-at-Bose

Lesson:
If you have more than one System, you do *not* have to keep all the pieces in sets as they were delivered.

Quoting Hilmar-at-Bose
By "carefully matched" we mean that all components of the system (drivers, acoustic enclosure, power amps, EQ, limiter, pre-amps, protection circuits etc.) are designed so that they really work optimally with each other.

On the other hand we are manufacturing to very tight specifications and tolerances. One L1 is virtually indistinguishable from the next one, so it's perfectly ok two swap speaker and power stands.
