1.) What is the difference between a Sonex Super Wedge and a Sonex Max Wedge?

Sonex Wedges, including Sonex Super and Sonex Max, provide maximum sound absorption for a variety of applications.

While Sonex Super Wedges are 12″x12″x6″ high, our Sonex Max Wedges can be customized to almost any dimension and thickness to meet your cut-off frequency and test area needs.

Sonex Max Wedges can be up to 61″ thick if a 63 Hz or higher cut-off frequency is needed for measurement according to ISO 3745 precision method.

The willtec foam used to manufacture Sonex Max Wedges also has advantages in that it is lightweight, easy to install and provides complete sound absorption at all frequencies, including high frequencies.

2.) How are both Sonex Super and Max Wedges installed?

  • Wall mounted- Sonex Super and Max Wedges can be mounted to the wall using acouSTIC adhesive and held in place by impaling pins to secure bond in place throughout the drying process.
  • Foam mounted- If applied on top of an existing flat surface melamine foam, acouSTIC adhesive should be used and then held in place by spikes through the side of the wedge to secure bond in place during the drying process.
  • Corner blocks are available for instillation to eliminate any gaps
