RE: Relevant loudspeaker tests

I had not seen this paper before. Thanks for posting it!

The early and mid 70s were a watershed period for audio. Between recording studio control room design, constant-directivity horns, TIM and crossover notch distortion discoveries, high output tape formulations, bi- and tri-amping becoming prevalent, parametric EQ, Thiele-Small parameters, 16 and 24 track tape recorders, and on and on, audio changed from the 50s-60s paradigm to a new world seemingly overnight. I was fortunate to be getting my education in that exact time frame.

Somewhat interesting related story - in about 1978, I used pink noise to evaluate and adjust a system I'd installed in a new nightclub (Bunky's, Madison, WI), and used a couple of UREI 529 3rd-octave equalizers to pretty-up the sound. The first performer there was Freddie Hubbard, who I got to hear for free! :)

I've read about half of the paper so far. B&K was on the right track. These days, it's common knowledge that speakers and rooms have a special relationship which is critical to achieving great sound.

:)
