Welcome to the RoomZorber line of acoustic products by GeerFab Acoustics.

Controlling sound waves reflecting in any music room is critical to a rewarding recording and listening experience. Deployment of absorption and diffusion products is key to a balanced-sounding room.

Absorption – wall panels, baffles, corner bass traps or clouds – is the single most effective way to lay the acoustic treatment foundation, and fiberglass is the best and most versatile broadband absorber.

Fiberglass comes in various densities, denoted as # or pcf (pounds per cubic foot). The most common densities used in acoustic treatment products are 1.5#, 1.65#, 2#. 3# and 6-7#. GeerFab Acoustics RoomZorbers use custom 2# Certainteed, 3# Owens Corning 703 and 6-7# Owens Corning 705 substrates.

Each density has its own unique absorption and cosmetic properties and its own set of installation methods. These are discussed on the individual product pages.

The RoomZorbers product line includes two MultiZorbers, so named because of the variety of mounting methods: the 2# MultiZorber II – an upgrade to the award-winning original MultiZorber – and the 3# MultiZorber OC703 with the famous Owens Corning 703 substrate and the innovative InvisiGrommet mounting system.

And then there’s the 6-7# ProZorber / TrapZorber / SkyZorber family. Currently, the ProZorber is available, with the TrapZorber and SkyZorber coming soon in 2017.

All RoomZorbers are Made in USA. In fact, the MultiZorber II and MultiZorber OC703 are Made in Milwaukee and the ProZorber is Made in Wisconsin!

About Us

GeerFab Acoustics is a full-service acoustic design and manufacturing company. Established in 2008 by Eric Geer, it quickly made a name for itself by quieting noisy restaurants, hospitals and offices. After landing high-profile projects like Kohl’s HQ, Marquette University and Ministry HealthCare and tuning several recording studios along the way, Geer found himself creating custom/hybrid products for the needs of particular projects. This led to the launch of the RoomZorbers line of acoustic products.

The original MultiZorber won the prestigious Best in Show award at the 2013 NAMM Show. The ProZorber debuted in 2015 and 2016 saw the release of the MultiZorber II and MultiZorber OC703 – the first retail-ready acoustic product utilizing the Owens Corning 703 substrate. Both new MultiZorber designs are US Patent Pending.

New for 2017 will be the TrapZorber and SkyZorber. Plans are already underway to follow those releases with the DiffZorber, PaintZorber, ArtZorber and VoxZorber. Stay tuned. Pun intended.
