The semester may be coming to a close but, learning is endless. Last week our senior consultant Andrew VonFeldt, PE gave a presentation with ECC at the Kansas Independent Colleges Association Business Affairs and Operations Conference in Newton, KS. The presentation was titled "Reimagining Facilities: Adapting Spaces for Modern AV Integration.” Special thank you to all who attended the presentation and ECC for asking us to co-present with them.

Our Senior Consultant, Andrew VonFeldt lectured at a KU Architecture class. This course tasks students to design a performing arts building that includes a black box theater and a recital hall. Andrew’s lecture focused on acoustic design requirements for such spaces. The acoustic component of this course provides architecture students with an opportunity to earn part of an acoustics certificate while pursuing their degree. The professor, Brian Gross, 10 architecture students, and Andrew toured the Black Box Theater at the Goppert Performing Arts Center at Avila University and the Swarthout Recital Hall at the The University of Kansas. The most recent renovation of Swarthout Recital Hall was designed by Avant’s founder, Bob Coffeen, while he was still teaching at KU. It's always a pleasure to discuss this space that’s a piece of our founders' legacy. Andrew is looking forward to returning to the class in the spring to offer feedback on the students' designs.

This past week, Avant Acoustics performed final system commissioning and training at Bellevue West High School’s new performing arts building addition in Bellevue, NE.

Avant provided full AV system design services and recommendations for room acoustics in the auditorium, theater, lobby, and supporting spaces. The auditorium was designed to support a wide range of educational and performance needs for the school’s active music and performing arts programs.

Bellevue West’s Choir, Band, and Theater teachers (pictured here with our Senior Principal Bob Ledo) were happy to see the system go online and receive hands-on training on their new mixing console and custom control interfaces.

Andrew VonFeldt, PE was project manager for Avant, with support from Bob Ledo and David Wetzel. Avant was glad to have worked with Ralph Gladbach from GP Architecture and systems integrator Bizco Technologies on this project.

After a career of over 40 years, most of which was spent at AVANT ACOUSTICS, Ed Charland will be retiring on December 12, 2025.

• University of Georgia Sanford Stadium (Athens, GA)
• Deutscher Bundestag Parliament Building (Bonn, Germany)
• Kiel Arena/Enterprise Center (St. Louis, MO)

Our team will uphold and embody his example of providing high-quality consulting services and strengthening client partnerships.

The entire team here at AVANT wishes him nothing but the best as he embarks on this new chapter, and we are all excited to hear about his next adventure at the lake!

Last week, we completed a site visit for Lone Jack Middle and High School in Missouri. They recently completed a multipurpose room expansion that features retractable theater seating, a mezzanine for operators, and a touchscreen-controlled audio-visual system. These updates offer more support for presentations and small performances.

We recently completed our training scope for Discovery and South Valley Middle Schools. These schools are nearly identical spaces designed to function as a combination auditorium, gymnasium, and storm shelter. The space will primarily operate as an auditorium, but the spaces need the ability to flex into the other functions. Our team spent a considerable amount of time working alongside the architect to design the finishes in the space that work acoustically to meet the required functions. We kept the same flexibility in mind while designing the audio-visual system to support the multiple functions of the spaces..
