not enough bass

[Dan_Proctor]

I just bought 2 s1 pro speakers. I like them but would like to get more bass. I have 2 b1 bass speakers from an old L1 tower that no longer works. Is there a way to line out and hook up the b1’s to the S1 pro speakers?

Wow! I just figured this out last night. I felt the same way about my 2 S1Pros, so I used my L1 Base and plugged in my B1 Bass module without the Line array into my T1 tone match. It solved my bass issue.

Thank you for your reply. Unfortunately my L1 base no longer works. I need something to power the B1's

Hi Dan Proctor,

Thank you for joining the Bose Portable PA Community.  Welcome.

Bose does not offer a companion subwoofer for the S1 Pro. It was intended for portable applications and to be run on battery power.

Question

Can you use the B1 Bass Module with the S1 Pro System

Answer

The B1 bass module is only compatible with the full-size L1 systems (L1 Classic, L1 Model 1S, L1 Model II). The B1 bass module is powered by a dedicated amplifier that is built into the power stand of those L1 systems.

The S1 Pro system is engineered to deliver great balanced sound without a separate bass module. It doesn't have an extra amplifier built-in for a B1.

As a matter of interest, the B1 bass module has two 5.25 inch drivers. The S1 Pro has one 6 inch driver.

Question

Can I use the PackLite^® power amplifier model A1 to power the B1 Bass Module?

Answer

The S1 Pro System Line Out is full range. Using this to provide a full range signal, the PackLite^® power amplifier model A1 to power the B1 Bass Module. That's not optimal because you will have frequency overlap between the S1 Pro System and B1 Bass Module (that was not designed to operate as a full-range loudspeaker.

You would need a crossover network with a low-pass filter to send only frequencies below approximately 100 Hz to the B1 Bass Module, but you might still need further processing with a parametric equalizer to make this combination work well together.

If you need more bass than the S1 Pro system provides on its own, Bose recommends you use one of the larger L1 systems.

I'm sorry your L1 power stand is not working.
