David Letterman’S High School Steps up to EV

April 11th, 2006

Performing Arts magnet Broad Ripple High School in Indianapolis, IN, is regionally renowned as the high school attended by talk show supremo David Letterman. The school office proudly displays thank you letters and top ten lists from Letterman. To further reinforce its reputation for excellence, Indianapolis Public Schools recently completed a $1.1 million acoustics and AV renovation at the school’s auditorium, including a compliment of sound reinforcement equipment from EV.

Architects Browning Day Mullins and Deirdorf were commissioned for the acoustical renovation in 2005, and hired Indianapolis-based acoustic and AV consultants Wright Consulting Associates, Inc., to specify the new sound system, replacing an aged system that could not keep up with the school’s growing performance demands - especially with regard to the low-end needs of hip hop. David Wright of Wright Consulting Associates explained why EV Xi loudspeakers were selected for the new 1000-seat auditorium:

“The original 1950’s room and subsequent acoustics had been modified and compromised over time and the room was not performing for music, drama, video or common speech applications. The original audio system only provided coverage for about 1/3 the depth of the room. In fact, a near riot occurred when the old system could not project enough SPL to provide crowd control during one particularly raucous student event!

Wright Consulting began this project by designing new diffusion panels for the walls and proscenium, to provide tight integration with the EV Xi systems we specified. Room reverberation and musical support was enhanced by both these custom diffusion panels -which cover up the old absorption material and wall “fuzz’ - and the use of EV dipole technology. We installed high performance Xi-2153 loudspeakers with an Xi-1152 delay ring for accurate, uniform projection. EV dipole allowed low frequency control we required to keep lobes out of the pit and off the stage below, plus off the acoustic panels above the speaker. This all added up to deliver the predictable clarity and low-end response the students had been sorely lacking; they do a lot of hip hop, and it’s hard to get an audience to respond to a performance if they can’t feel the bass. This isn’t an issue any more!

This project was unusual as we faced no compromises in integrating professional sound with professional acoustics - as dictated by the architect. This was a rare treat in an industry where aesthetics often compromise speaker locations! The room now enjoys SPLs capable of exceeding 95 dBA continuous, with full fidelity and high speech clarity for all manner of applications. Various EV microphones ensure high quality audio at the other end of the signal path. The system has received rave reviews from the community and the school drama department - another problem solved with EV!“
