This model accelerometer was chosen for a prototype of a servo subwoofer. Its linear response and high resonant frequency of 85kHz offered distinct advantages over the inexpensive piezo accelerometers. The accelerometer was easily mounted on the woofers dust cap and because of its low weight of 1.8g, there was very little distortion produced by any deformation of the dust cap. The frequency response of the accelerometer was well below 4Hz and actually quite flat out to 30kHz. Its high output and low output impedance made cabling easy. Any speaker engineer would confirm that an accelerometer with these specifications are ideal for a servo (motional feedback) woofer. The system worked well with a number of different LF drivers. Stability was not an issue with this accelerometer, unlike inexpensive piezos. THD was reduced well over 20 dB. This accelerometer retails for 0. High reliability.
