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 woofers 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
