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 acoustical consulting and audio visual system 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 audio visual consultants.
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
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.
