Created: 01 December 2010

All loudspeaker measurements are performed independently at the National Research Council of Canada. All measurement data and graphical information displayed below are the property of the SoundStage! Network and Schneider Publishing Inc. Reproduction in any format is not permitted.

Note: The B1 loudspeaker shows a frequency-response anomaly at about 350Hz when the measurement microphone is placed in front or to the rear of the cabinet. It's because of the way the two woofers are configured -- the sound waves are "wrapping around" the cabinet and causing a cancellation to the front and to the rear. Noting this behavior during the measurement process, we performed an additional frequency-response measurement with the microphone positioned at tweeter height but pointed directly at the midpoint of one cabinet side to show the woofer-summing behavior in this measurement position. We published this additional graph below (C) in the "Frequency response and sensitivity" section.
