L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

Hi Jim,

Welcome to the Bose Portable PA Community.

I use an L1 1S with B2 Bass and since the top array is 12 speakers, I would like to add a bottom array to make it 24.

If this can be done, How can I obtain the bottom array?


Unfortunately, there's no way to convert an L1 Model 1S (12 drivers) into an L1 Model II (24 drivers).

Only the L1 Model II has 12 drivers in the lower section of the array.

The Cylindrical Radiator® (array) and the Power Stand of the two models, are not interchangeable. Each model is only available as complete unit (Cylindrical Radiator®  plus matching Power Stand).

Bose doesn't have an upgrade option but you may be able to find a dealer who will take the L1 Model 1S as a trade-in toward an L1 Model II. That's outside any Bose involvement.


Hi LarryO.

I'm sorry you're disappointed. Even though the Power Stands of the two Models look identical, they house different electronics for the Cylindrical Radiator®.

  • Model 1S Power Stand will power 12 drivers
  • Model II Power Stand will power 24 drivers

The Model 1S Power Stand can't power the 24 drivers of the Model II Cylindrical Radiator®.
