Passive (unpowered) Loudspeakers

L1 Classic This information is applicable to the L1 Classic

L1 Model I This information is applicable to the L1 Model I

L1 Model II This information is applicable to the L1 Model II

Using loudspeakers other than the B1 Bass Module with any of the L1® systems is not supported. However you can safely try your own external subs if the impedance is no lower then 4 ohms (typically a single 4 ohm loudspeaker or two 8 ohm loudspeakers in parallel). The output from the Power Stand is 250 watts RMS into 4 ohms.

L1® Classic and L1® Model I

L1 Classic This information is applicable to the L1 Classic

L1 Model I This information is applicable to the L1 Model I

For the sake of those attaching third party passive speakers (an unsupported application).

Output if no B1 Bass Modules detected

  • 40-180 Hz Bandpass (that is: NO B1 EQ)

If one or two B1 Bass Modules detected (or resistors used across NL4 2+ / 2- pins to emulate detection)

For more details about the Power Stand outputs see: PS1 Power Stand / Bass Line Out

L1® Model II

L1 Model II This information is applicable to the L1 Model II

For the sake of those attaching third party passive speakers (an unsupported application).

Output if no B1 Bass Modules detected

  • 40-200 Hz Bandpass (that is: NO B1 EQ)

If one or two B1 Bass Modules detected (or resistors used across NL4 2+ / 2- pins to emulate detection)

For more details about the Power Stand outputs see: L1® Model II Power Stand / Bass Line Out


Active (powered) Loudspeakers

L1 Classic This information is applicable to the L1 Classic

L1 Model I This information is applicable to the L1 Model I

L1 Model II This information is applicable to the L1 Model II

Using powered loudspeakers with any of the L1® systems is not supported.

The PackLite® power amplifier Model A1 is part the L1® System. It can be used to power up to two B1 Bass Modules. This is connected to the Power Stand Bass Line Out.

Third Party (non-Bose®) Systems

If you want to use a powered loudspeaker system, you can use the Power Stand Bass Line Out as the signal source. Here are notes specific to the L1® you are using.


You will probably use an powered loudspeaker in the same way as you would connect an PackLite® amp.

Please see PackLite® power amplifier Model A1 for extensive notes that include ideas that can be applied to other systems.
