Through Acoustics and AV Design

Who We Are

Andrew D. Siebert, PE

Andrew D. Siebert, PE

President

Drew feels so blessed having the opportunity to lead one of the most capable acoustical consulting and audio-visual design teams in the country. He sincerely enjoys working with the other consultants at AVANT ACOUSTICS and strategizing on how to bring our “more complete” services to more owners, architects, and venues across the globe.

A Professional Engineer licensed in the State of Kansas, Drew understands the importance of client relationships. While the project at hand is of utmost importance, Drew is also focused on the long-term client relationship. He is excited to be leading AVANT into our next half-century.

Drew received his Electrical Engineering degree from Kansas State University. Several years later, he followed that up with a Masters of Business Administration focusing on business strategy and finance.

When not working, Drew prefers to spend time with his family.  He and his wife, Amy, have two children who keep them extremely busy. Camryn is seven and Cecil is five. You might find the Siebert family at a local park or pool enjoying the outdoors during the summer or perhaps doing science and engineering educational experiments at their Overland Park, Kansas home when the weather outside isn’t so friendly.

Senior Vice President

For 28 years, Bob’s creative audio-visual design and enthusiastic leadership have maintained AVANT ACOUSTICS’ leadership position in the market.

As Senior Vice President of AVANT ACOUSTICS, Bob is actively involved in the design, testing, and commissioning of audio-visual and sound reinforcement systems for all types of facilities throughout the United States and in Germany, Japan, and Korea.

When not designing, testing and commissioning systems – or at KU games – Bob might be off sailing, flying, or running a marathon (yes, he is fast!).

Bob attended Oral Roberts University in Tulsa, where he earned a double major in Telecommunications and Business. He also serves as a guest lecturer for university classes in digital audio.

Bob and his wife (the best cupcake baker ever) live in Olathe, Kansas, with their dog Piper, where they host our wildly successful (or maybe just wild) AVANT pool party in the hottest days of the summer.

Hy-Vee Conference Center

This $15 million project at Hy-Vee’s Corporate Headquarters included a conference hall that subdivides into multiple configurations, a pre-function lobby, standalone conference/training rooms, a kitchen, and a cafeteria. 

AVANT ACOUSTICS provided the following services:

  • Acoustical consultation
  • Audio-visual system design, construction administration, and system commissioning

Project Highlights:

AVANT ACOUSTICS provided consultation and design for an extremely flexible video routing and production system for the conference hall and surrounding spaces.  The system is capable of routing video from any of the spaces to any of the four large projection screens in the hall and any of the many flat panel displays located throughout the lobby and ancillary spaces.  The projectors and screens in the conference hall were designed to retract into the gaps between the ceiling clouds so that they disappear entirely when not in use.  The loudspeaker distribution for the hall is also hidden in the gaps in the ceiling clouds and provides high-quality audio reinforcement to the entire hall.

AVANT also provided commissioning services that included the configuration of a fully-redundant audio network, as well as the creation of intuitive, user-friendly graphical interfaces for controlling the system.  The control system allows the conference hall to be divided into multiple smaller spaces for smaller events.


Location: West Des Moines, IA
Facilities: Conference Hall, Lobby, Conference & Training Rooms

How We're Different

Focus

Focus

We are a small firm located in the heart of America, just outside of Kansas City. Unlike some other firms that offer a huge array of services, we focus on acoustics and audio-visual systems design because we love this work, and we do it really, really well. There aren't many experts out there with the depth of knowledge and breadth of experience of our consultants.

Longevity

Longevity

Since 1964, AVANT ACOUSTICS has been delivering easy-to-use systems that sound and look outstanding. Many of our clients come back project after project, including our first ever client - Washington Dulles International Airport, who is a client to this day. We keep clients happy by only designing with the latest proven technology and consistently meeting deadlines and budgets.

Relationships

Relationships

On most of our engagements, there are two key relationships. One is with the owner...looking out for their best interests and ensuring decisions are made for their benefit. The second is to the architect... helping to deliver their vision for the space, and ensuring the acoustical treatments or audio-visual system supports that vision.
