Excelsior Audio features a lab specifically for loudspeaker measurements. Our focus is on performing directivity balloon, sensitivity,
maximum input voltage, and other measurements to characterize loudspeaker system performance. These measurements are the primary data
required for use in building loudspeaker modeling files (e.g. GLL and CLF). We will continue our work to author GLL file for our clients based
on these of measurements.
The Excelsior Audio lab is positioned to fulfill almost any of your loudspeaker measurement and modeling needs. Charlie Hughes has over
25 years of loudspeaker design and measurement experience. He was one of the first to adopt and work with the GLL format for modeling loudspeaker
performance. Charlie's close work with AFMG (makers of EASE, EASE Focus, EASERA, SysTune, and other electro-acoustic simulation and measurement
software) over the years allows him to help you to make sure your loudspeakers are modeled in the best way possible via the right type of
GLL (yes, there is more than one type). As one of the main authors of the user's manual for AFMG's SpeakerLab program, Charlie helped to literally
write the book on the software used to create GLL files.
We are pleased to be one of only a handful of independent labs world-wide providing measurement and GLL/CLF authoring services.
If you are a loudspeaker manufacturer, sound system design consultant, design-build firm, or someone that needs objective measurement data for
your loudspeakers please contact us.
