I’ve knocked out a little web page to show some of the MLSSA measurements I’ve made over the years, with interpretations of the time, frequency, and waterfall displays. There’s a fair variety here: A Celestion SL-6, Klipsch Chorus before and after time-alignment, Quads solo and stacked, a Martin-Logan CLS II, two different audiophile drivers used in very expensive American high-end speakers, my own Ariels, and the 12″ Tone Tubby AlNiCo guitar speaker.
In addition to the data, there’s comments about weighting first-arrival vs overall room frequency-response curves, how to find resonances that are 20dB or more below the main signal, and some unusual distortions in the time domain. These are the kinds of things that are undetectable on 1/3 octave real-time analyzers, or swept sinewave measurements - it’s why I tell people to invest in a MLS-capable measurement system with a highspeed sound card, so you can see, not guess.
Hi Lynn, Nice site. I have often lusted for more mesaurement toys … to date, the finest response measurement was John @ looking around my Audio Dungeon for the “other speakers”
Now if you could find a old ‘lunch box’ style PC
that would make a great traveling system.
