Ok, so after a few months of work -- I am pleased to say that I have developed a complete computer automated setup for an entire suite of loudspeaker measurements....
What normally took me perhaps 8 hours of engineering work -- can now be completed in under 30 minutes -- and I don't even have to be in the lab
Measurements included in the suite:
*Quasi-Anechoic on-axis full range frequency response
* Horizontal dispersion (15, 30,45 degs off-axis - to right and left)
Vertical dispersion and symmetry (5, 10,15 degs off-axis - above and below)
*Listening window (an averaged response that best represent what the listener hears -- averages both on-axis and off-axis measurements)
* Impedance + Electrical Phase (also called a Bode plot)
* Waterfall CSD plot (Cumulative Spectral Decay)
I think this covers it all -- is there anything else you guys would like to see?
Also, would you prefer I post the graphs unsmoothed or 1/3 octave? Using a 5dB scale or 10dB scale? Understand that if I post measurements of our products using 1/3 octave smoothing and a 10dB scale (like many other manufacturers) -- the response plots will look *almost* like perfectly straight lines...
Personally, I like the completely unsmoothed graphs on a 5dB scale as they are extremely revealing --- however --- much of the general public might not understand this difference in scaling and smoothing and they might wrongfully assume one loudspeaker is more linear than another based on these scaling differences...
Curious as to your thoughts...
Thanks!!!
