Uncoupled Array Design: Beginnings and Endings (Updated)

** Update:  A downloadable version of the calculator to do this work is available (courtesy of Daniel Lundberg). Go to the bottom of this post for preview and instructions.  ______________________________________ When a coupled array is assembled, its operating range is limited primarily by its power capability. Even very large arrays will congeal fairly quickly and once […]

A Concise Article on Cardioid Subwoofer Arrays – by Steve Bush

This article  Tech Talk: Building Directional Subwoofer Arrays Working toward consistency. was posted just today on the ProSoundWeb by Steve Bush. Well written, concise, plain English and NO MATH!  (lo siento que no es Espanol pero tiene fotografias). I need say no more.  Geez.  That was the easiest post I ever did! 6o6

15 Musicians and No Sound System

I went to see Wynton Marsalis and the Jazz at Lincoln Center Orchestra (JLCO) last night at a vintage hall here in St. Louis, The Sheldon Concert Hall (730 seats). I went for 2 reasons. First, a compelling interest in Jazz music and second, the opportunity to hear a big band in a hall correctly scaled for […]

Phase alignment of spectral crossovers

This is a continuation of the impulse response subwoofer thread. Here are some screens from Sounds Systems: Optimaztion and Design that deal with phase alignment of crossovers. The figure above shows the phase responses brought together between sub and main.  The crossover is not steep and therefore the phase response overlap over a wide range. […]

Line Array Gain Taper (Breaking the Line II)

After Bob Gardam’s comment on Breaking the Line I decided to give a quick go of the hypothetical scenario I had proposed in my reply: 12 boxes,  6 @ 2 degrees @ 0 dB, 3 @ 4 degrees @ -2 dB, 3 @ 8 degrees @ -4 dB. I made screen dumps of 3 scenarios: 1) 0,-2, […]

The modern science of room tuning

I have never really considered myself a scientist. I don’t have a Ph.D.  I have a brother who is an MD, a sister with a Ph.D in neuroscience, another with a doctorate Latin American studies, an MBA sister, a brother with Ph.D in astronomy, one more sister with a Ph D (psychology) and Matt the lighting […]

And you think you have it rough!

So you wish you had some better tools. Geez, why do I have to carry this rack full of test gear around. I wish we could just reduce it down to half the size. And then we did. Well I just wish we could get it down to where it was just a card in […]
