Talk:Bose S1 Pro Compared to Bose L1® Compact

Speaker array and power

Bose Professional HI Jimmy and Victor. Good question. The S1 system runs at 40 watts. It sounds small but we wanted to make the S1 as efficient as possible to achieve the best possible performance for it's size, especially if you are using the optional battery. The S1 has a 3-element array so you get more coverage and SPL, and since the drivers are precisely matched to the Class-D amp inside and controlled by Bose DSP, you can expect surprisingly big sound for it size. Hope this info helps! Remember that power is not always indicative of performance. LED light bulb power is a good example of this.

Auto EQ Accelerometer

The S1 detects placement changes through an internal accelerometer sensor. It really looks at tilt back, flat and monitor mode (on it's side). Your question: How does it know it's on a stand? There's a microswitch inside the pole cup that detect the presence of a pole and sets the EQ accordingly, The pole-mount is considered the S1's "flat" state while the other positions adjust mostly to reduce the bass due to the hard boundary surfaces that naturally contribute to the low end.
