Meeting Notice for Sunday, November 25, 2018, 6PM

Place: Boston University, Life Science & Engineering Bldg, 24 Cummington Mall, 1st Floor Conference Room 103, Boston, MA 02215

Guests: Keith Larson, Smith & Larson Audio (http://www.woofertester.com/download.htm)

Topic: A new, more precise method of measuring woofers without an anechoic chamber

Keith Larson of Smith and Larson Audio will be presenting a new, nearly anechoic method of measuring while combining the woofer’s output and port response. Their measurement technique can be traced back to the earliest days of mathematical analysis of loudspeakers.

Surprisingly, only Smith and Larson Audio sell a product that fully implements the original theory. Additional methods of measuring and modeling driver response will also be discussed and demonstrated. These new methods are integrated into the Woofer Tester Pro & Speaker Tester.

Additional features of the software + hardware are:

  • A high power current sensor and calibration resistor.
  • Additional software features engineered to make speaker testing easy to understand and implement.

Refreshments will be available at 5:30PM
