Wattnatt, I think that's cute. I didn't realize that SPL measurements were obscure technical jargon. They have been used for most of the last century and are part of the Vandersteen literature. So your beloved Rickie Vandersteen hides his glorious speakers behind obscure technical jargon?
One would think that freqency respose, modulus of impedance plotted against phase angle and freqency, and SPL measurements are the three most basic, and easiest to measure metrics that are applied to loudspeakers. And again, they have been in use for over 50 years.
As far as the ad hominem part of your arguent goes, only a child attacks the messinger when the message is too complex for his little brain to process. Better to ask questions and do a wee bit of reasearch first.
