== Using a Bose B1 with the S1 Pro or S1 Pro+ ==
== Using a Bose B1 with the S1 Pro or S1 Pro+ ==
 
=== Summary===
Using a B1 with the S1 Pro or S1 Pro+ is not recommended. Consider using a Sub1/Sub2 as these were designed to be compatible with the S1 Pro/S1 Pro+
=== The B1 Designed for L1 not S1 Pro/+ ===
The Bose B1 Bass Module was designed for the L1 family of systems, not the S1 Pro or S1 Pro+. The S1 Pro+ provides a full‑range line output, while the B1 requires a dedicated low‑frequency signal and a matched amplifier to operate correctly.
The Bose B1 Bass Module was designed for the L1 family of systems, not the S1 Pro or S1 Pro+. The S1 Pro+ provides a full‑range line output, while the B1 requires a dedicated low‑frequency signal and a matched amplifier to operate correctly.


To use a B1 with an S1 Pro or S1 Pro+, you would need extra equipment such as a crossover, a separate power amplifier, and additional cabling. This adds cost and complexity, and the results may not match what the B1 delivers when used with an L1 system.

For simple, reliable bass reinforcement, the Bose Sub1 is the recommended companion for the S1 Pro and S1 Pro+. It connects directly, includes the correct crossover and protection, and provides deeper, more powerful bass with no extra gear required.

The B1 Bass Module is a band‑pass enclosure optimized for use with L1 systems. When connected to an L1 Model I/II/1S, the internal DSP in the power stand generates a dedicated bass signal for the B1. This processing:
The B1 Bass Module is a band‑pass enclosure optimized for use with L1 systems. When connected to an L1 Classic/Model I/II, the internal Digital Signal Processor (DSP) in the power stand provides a dedicated bass signal for the B1. This processing:


* Restricts the B1 to its intended operating range (approximately 40–200 Hz)
* Restricts the B1 to its intended operating range (approximately 40–200 Hz)
Line 17: Line 19:
* Routes the processed signal to a dedicated 250 W @ 4 Ω amplifier (internal or PackLite A1)
* Routes the processed signal to a dedicated 250 W @ 4 Ω amplifier (internal or PackLite A1)


The exact DSP topology has not been published, but the result is a controlled band‑pass feed that keeps the B1 operating safely and musically.
The result at the L1 Bass Line Out is a controlled band‑pass feed that keeps the B1 operating safely and musically.


The S1 Pro and S1 Pro+ do not provide this processing. Their XLR Line Out is full‑range and unprocessed.

Line 30: Line 32:
Without this processing, the B1 will not perform as intended and may be at risk of low‑frequency over‑excursion if driven hard.

For bass reinforcement with the S1 Pro or S1 Pro+, the Bose Sub1 is the recommended solution. It includes internal DSP, limiting, crossover management, and a built‑in 480 W amplifier, and accepts a full‑range line‑level signal directly from the S1 Pro/S1 Pro+.
