Passive (unpowered) Loudspeakers
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
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)
- 40-180 Hz with different EQ curves
For details on how to do this see: Activating B1 EQ Curves
For extreme details see: Bass Output for Experts / Classic / Model I
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)
- 40-200 Hz with different EQ curves
For extreme details see: Bass Output for Experts / Model I
For details on how to do this see: Activating B1 EQ Curves
Active (powered) Loudspeakers
Using powered loudspeakers with any of the L1® systems is not supported.
PackLite® power amplifier Model A1
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.
