In-Depth: Our Process With Your Church


Every worship space has its own unique acoustical signature. Furthermore, each congregation has its own goals for the use of their worship space. Taking these goals and making them reality is what our experienced team can do for your church.

For example, if your church offers a more traditional worship service typically with a pipe organ, a naturally-reinforced choir, and a singing congregation, then a slightly more-reverberant worship space may best suit your needs. However, if your church prefers a contemporary service - which oftentimes includes percussion, low-frequency musical instruments such as a bass guitar, and vocalists a less reverberant worship space may work best.

Regardless of your needs, our acoustical department will consider your church's goals and recommend treatments or techniques that will correct the acoustical problems that have hindered you in reaching your goals. In cases of construction and remodeling projects, our staff can reduce costly post-construction fixes by working with your architect to ensure the project is acoustically designed around your congregation's functionality needs during the initial construction phases.

A/V Systems

Designing an audio/visual system within a worship space or fellowship hall is a subjective task. There exists no single "boxed" solution that can work for all churches in need of sound reinforcement and visual systems. Each church is simply too unique in their acoustical properties, their worship practices, physical layout, and their congregation's goals to approach every system design in the same way.

Our willingness to take the time to understand each client's needs makes our services truly tailored to each house of worship client. After 30+ years in the acoustical & A/V business, we know that having the right skills, the correct engineering tools, decades of experience and by asking the right questions our clients will receive the results they desire.

For example, traditional worship services generally require sound reinforcement systems that concentrate on excellent speech intelligibility. However, a church that prefers a more contemporary service would require a system that provides higher sound pressure levels, as well as extended low and high frequencies. All churches may want the inclusion of visual enhancements such as a video presentation system, cameras systems and special stage lighting to meet the needs of the congregation.

RDI utilizes computer-aided modeling techniques to examine various system components before actually installing them in a facility. This technology gives us the ability to determine such items as speech intelligibility, direct to reverberant ratios, sound pressure levels, coverage patterns, proper aiming, and much more.

Along with their proven expertise, our design team has the desire and ability to listen and understand the needs of each individual congregation. Whether your needs and goals consist of enhancing an existing system or designing and implementing a new one, our staff can help you meet those goals.
