  • Ported Information - Formula for calculating port length and measuring Fb

Ported Boxes

  • DIY Servo Sub ~ This project was a 4 month long trial with little reward.  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.
