Technical Information

Recommended Amplifier
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (or RMS)
power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels, and other
factors. As a general guideline, the following table provides recommended power amplifier ranges.
Model Nominal Impedance
MB210 8 Ω
CAUTION: Failure to follow these guidelines may result in damage to the loudspeaker.
The Bose® PowerMatch configurable power amplifiers offer optimal amplification, amplifier limiting, digital signal
processing (DSP), and DSP presets for use with the MB210 Compact Subwoofer. Please refer to the specifications
listed on the pro.Bose.com website for amplifiers and compare with the table above to determine which model is
best for your particular system design.

Recommended Signal Processing

Digital signal processing (DSP) is required for infrasonic bandpass protection, amplifier power limiting and active
crossover for the MB210 loudspeaker. Bose PowerMatch and PowerShare amplifiers provide recommended
bandpass protection and amplifier limiting functions.
Bose ControlSpace® DSP hardware, including the ESP-880, ESP-1600, ESP-1240, ESP-4120, and ESP-00, can also
be used to provide bandpass protection and active crossover.
The latest Control Space Designer software for PowerMatch, PowerShare, and DSP hardware, which contains the
latest MB210 preset files, can be found in the Software section of pro.Bose.com.
The following table lists the recommended infrasonic bandpass protection and amplifier limiter settings for the
MB210 loudspeaker.
