Bag End gives Convocation Hall a Serious Sound Upgrade

Lewis University purchased St. Charles Borromeo property in the summer of 2013. This property adjoins the campus, and accommodates the increasing enrollment and expansion of its academic programs. 

To fit the University’s needs, extensive renovations were needed throughout. The current space includes classrooms, meeting rooms, a dining room and residential living spaces. There are also multiple private offices, a chapel that accommodates up to 750 people, a small gymnasium and a convocation hall. 

The Convocation Hall

Lewis University and their contractor, Conference Technologies, consulted with Bag End to improve the sound in the convocation hall. The hall is primarily used for concerts, rehearsals and auditions by the Metropolitan Youth Symphony Orchestra (MYSO). We recommended some serious acoustical treatment for the hall. Two Bag End Crystal2-I mid-high speakers were chosen and pointed out to the main audience. In addition, two Bag End CDS-110’s were used and pointed at the front sides.

The mid-high speakers are mounted high up on the walls above and behind the stage and the performers. Most importantly, good directivity and a flat response make this location possible. The front rows are very well covered without front fill speakers. There is no feedback problem even with the mains behind the performers and mics.

Two custom Bag End bass columns were spaced out in a sparse low frequency array. Each column is 24 feet tall with eight 12″ speakers, moreover they are Infra processed down to 8 hertz with a Bag End INFRA-MXB processor. This provides even bass coverage at every location of the room.

Henry Heine, Bag End’s acoustical engineer, returned after installation to help tweak the system to ensure it met expectations.

Jim Wischmeyer of Bag End commented, “It’s pretty amazing how even and natural the coverage is from the stage on out. With light acoustic music the direct sound is heard slightly in front of the amplified sound so the source orientation and image to the performer is beautiful. The bass level doesn’t change by more than a few dB from standing on the stage in front of the bass column, to the middle or back of the room.”
