Customer Reviews

3 reviews for Sonex® Contour Panel

  1. Verified Customer

    used on a ceiling. the panels are irregular and installing them directly in contact with each other is a mistake. it should also be noted that the part where they are supposed to be installed into a climate controlled environment 60 degrees 40% relative humidity should not be in the fine print.

  2. Verified Customer

    Used on the reception area of an Animal Hospital ceiling, look amazing and do even better at quieting the room.

  3. Verified Customer

    Wonderful addition to a performance space — just the right amount of dampening. On a ceiling at 11 feet, looks beautiful.
