SVC online – Array or not to array: Part 1 – Additional data

At long last I have found some time to post here again. Well actually I don’t have the time but I did it anyway. The thing is – I left a trap in an article I wrote that would force me to make time here – and it worked!   This will be brief – […]

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.

Macau COD Tuning: Day 1

I am currently in Macau. If you don’t know where Macau is, study up on the history of the Portuguese Empire. Macau,  the #1 gambling destination in the world has now reverted back to ownership by the People’s Republic of China and like all gambling operations serves as a funnel of money back to the […]

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 […]

Sound Systems: Design & Optimization – 2nd Edition

The second edition came off the press in October of this year and I am quite happy with the result. First thing is that the book can sit on your lap or a table without flopping around. The graphics came out much better. I was able to get them reformatted so as to get the most […]
