Subwoofer Delay Taper (Update 1)

Here is a quick preview of my next post.  These plots contain concentric circles. Each represents a wavelength traveled from the speaker at 125 Hz (2.73 meters). The first one shows 7 speakers spaced at 1/2 wavelength (1.37m) and all set to 0 ms delay. The concentric are all the same for the 7 speakers […]

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

Cardioid Subwoofers

A hot topic of discussion is cardioid subwoofers, so this will be the place to get that topic going. At the moment I will use this as a test to see if I can upload a few graphics from the book here.  The first will be some pics that describe the behaviour of end-fire arrays. […]

SIM3 Optimization & Design Seminar at UC Irvine

We just completed a 4-day SIM3 training seminar in the south side of southern California. UC Irvine is located very near the ocean, which makes one wonder how folks could study when the surf’s up. It is also right next to John Wayne Airport. Naturally I flew in and out of LAX, and drove the hour down to the other […]

Macau COD Tuning: Day 6 – Constellation

Constellation Tuning Most of today was dedicated to Constellation tuning. Steve Ellison programmed up the menu of user-settable presets that will become the painter’s pallette for the system designers, Francois Bergeron and Vikram Kirby. The pallette gives them easily understood parameters such as the the reverb Time, gain, etc, that will allow them to tailor the response […]

Macau COD Tuning: Day 5 (Cardioid sub day)

Looking for Mr. Cardioid During the daytime (remember that we start at 11pm) the crew set up 2 measurement mics for us high in the grid. The mics were placed as a front/back pair in the near field of the coupled subwoofer array. The goal was to measure the responses in front and behind on the center axis […]

Macau COD Tuning: Day 4 (Work in progress)

 Note: I have completed day 5 at the time of this writing – I am posting this work in progrees so that the posts will come out in the right order – I will fill this one in ASAP Bus level adjustments for equal level One of the major components of an LCS-based system design […]

Macau COD Tuning: Day 2

Day 2: Day 2 was spent finishing the tuning process for the Main arrays (to the 1/2 point) Now that we have done all 4 arrays we will copy the the settings over to the other side and then verify the symmetry of the other speakers. We are setting that part aside, moving on instead with […]

Off to Mexico for AES and SIM3 Training – Updated

I have been busy putting together new material for SIM 3 training, and AES seminar and the upcoming Broadway Sound Master Class. You have seen some of the work in progress below, but I have had to push to get things ready for showtime.  Sorry for the delay in getting more things posted and for […]

Phase Wavelengths: The End Fire Cardioid Array made visible

The end fire array is one of the most talked about, even if not the most often implemented of the cardioid subwoofer arrays. It can be a challenge to wrap our heads around how we get the speakers to play leap-frog in the forward direction and demolition derby on the back side. Looking at the […]
