DIY Servo Sub ~ Read about what we went
through trying to develop a simple feedback controlled subwoofer using
an accelerometer and a bunch of op-amps. This was a Senior
Project finished in April of 2000.
Impedance Analyzer ~ The ability
to accurately and quickly measure the tuning frequency of almost any
ported, PR or bandpass enclosure. Also measures impedance peaks
for finding fB of sealed enclosures. A must for any hobbiest.
