In this article, George Ntanavaras describes the design and operation of a system consisting of the ACH-01 accelerometer and a preamplifier with an integrated analog signal processor. With this system, it will be possible to measure the acceleration, the velocity, and a loudspeaker cone’s excursion at the low frequencies. Also, a loudspeaker cabinet’s panel vibrations will be easily obtained. Originally published on audioXpress June 2011.
