Broadway panels may be mounted using various methods to suit your specific application. In addition to using typical screws and adhesives Primacoustic has developed a series of impalers to provide the installer with a simple, quick and effective method of mounting Broadway acoustic panels onto walls without causing serious surface defacement.
Each Impaler features a series of sharp protruding darts that penetrate the panel to secure it in place. To ensure panels do not get dislodged after installation, applying a dab of construction adhesive to the Impaler during the mounting process adds another level of security and reduces opportunity for tampering. Impalers are installed using typical sheet rock anchors and screws.
Alternate installations that can be considered include direct screw down using a long screw and retaining washer. This is typically accomplished using a standard screw and a wide faced washer to hold the panel in place. This is a good option in industrial installations where panels may find themselves in harms way or need to be secured on ceilings. Velcro is also a possible option where light duty installations are needed. Finally, for permanent installations, construction adhesive is used by applying a generous bead around the circumference and then crossing from corner to corner. Use a Surface Impaler to anchor the panel while the adhesive cures.
Used to hang Broadway panels like a picture. The Surface Impaler is quick to mount and is ideal for installations where panels may need to be relocated.
Designed for quick fitting and easy alignment, the Push-On Impaler is the 'contractor's choice'. It lets you create large absorptive surfaces by butting panels together.
The Off-Set Impaler increases bass absorption one extra octave by introducing a 3.5" (9cm) air cavity behind the Broadway panel. Ideal for studio, home theater and house of worship.
Designed to be used with the Broadway Broadband absorber, the Corner Impaler introduces a 17" (43cm) air cavity behind the panel for amazing bass absorption.
The most common approach to mounting Broadway panels is directly on the wall surface. Primacoustic Surface Impalers make this process easy. All you do is screw a couple of Impalers to the wall and hang the panel like a picture. If they will be in a high traffic area, add a small dab of construction adhesive in between the Impaler and the panel to lock it in place.
Depending on the size of the Broadway panels you have selected and the degree of security you feel you need, a different number of impalers will be required. The minimum number of impalers for Broadway panels are detailed below. Impalers should be spaced so there is approximately a two inch boarder from the edge of the impaler to the edge of the panel. Make sure the impalers will clear the fabric that wraps around the back. Avoid pushing the impalers through the fabric edge.
Broadway panels are heavy enough to cause injury should they fall from a height. When mounting Broadway panels in overhead locations ensure there is sufficient impaler clips to prevent accidental dislodgement.

A wonderful trick with acoustics is to add an air space behind the panel to increase the bass absorption. Depending on the panel density, this can be as provide as much as an extra octave lower, and up to 30% increase in absorption across all frequencies, without any additional cost. Creating an air space behind the panel can be done by furring the panel out using wood slats or by using Primacoustic Offset Impalers to create a 3.5" air cavity behind the panel.
There are two aspects to mounting Broadway panels. The first is deciding where they should go for maximum effect and the second is the physical act of putting them up on the walls.
Panel placement is really a matter of application. For instance a recording studio will benefit from more absorption while a hotel lobby or restaurant can work well with minimal treatment. The following table shows general wall treatment coverage for various applications.

As you no doubt noticed, most rooms—even studios—are rarely covered from floor to ceiling. Most are kept relatively live and natural. This provides us humans with a sense of natural space which is comforting. When rooms are overly treated such as an anechoic chamber, we find ourselves lost or even off-balance with a sense of vertigo.
Depending on the room, panel placement will also change. For instance in a restaurant or office, simply getting panels up on the walls will help tame conversations and the sound of computers. Placement in cases such as these is usually based on practicality such as where wall surfaces are available. In some cases, a more even or balanced approach is preferred by spreading out the absorptive panels so that everyone enjoys the same environment. Meeting rooms are a good example of this.
In more demanding critical listening situations, more advanced panel placement is preferred. The most common configuration is known as a live-end, dead-end (LEDE) whereby one end of the room will have a greater percentage of absorption than the other. In a studio, the source end tends to be treated more heavily while in larger rooms such as theatres, the rear of the room tends to have more treatment.
