L1® System Holistic View
A Holistic View of the L1® 
The L1 System (Physical)
Here is one way you can think about the L1 System.
L1 Cylindrical Radiator® loudspeaker as one loudspeaker
Think of the L1 Cylindrical Radiator® loudspeaker (Yellow highlight) is a single loudspeaker with 24 drivers (2.5 inch) supplied by 500 watts for the L1 Classic and 250 watts for the L1 Model I. Note: the L1 Model I provides the same audible output. It is just more efficient than the L1 Classic.
Two B1 Bass Modules as one bass loudspeaker
The L1 System (Amplifiers & Power)
The L1 Cylindrical Radiator® loudspeaker This is one loudspeaker that happens to break down into two pieces for travel. This is driven by two separate amps, but this is not important because under normal circumstances both amps are driven identically. One drives the top half of the L1 Cylindrical Radiator® loudspeaker and the other drives the bottom half. Because the L1 Cylindrical Radiator® loudspeaker should always be operated as a single unit, what happens when you break it down isn't relevant.
If you don't use the B1 Bass Modules at all, the amp that is normally used to drive them is idle.
Use the proper cables
If you are using a B1 Bass Module with your Power Stand it is ESSENTIAL for proper operation that you use the BLUE cable supplied with the B1 Bass Module or B2 Bass Module. This is required so that the L1 Classic/L1 Model I/L1 Model 1S/L1 Model II Power Stand can correctly identify when there are bass modules connected to it and if so, how many.
Please click the picture above for ordering information.
- The B2 Bass Level Switch will not change the sound of the B2 Bass Module if you are not using the correct cable.
See: PS1 Power Stand / Bass Line Out for details about how the Power Stand adapts to the number of bass modules are connected to it.
You may also use high quality NL4 cables (four conductor cables). Alternate and longer cables for B1s
