Origins

In late 2009 a friend asked if I could help “fix” his home studio control room. I suggested he build the same type of cylindrical diffusors I had been recommending for more than 20 years, based on a lot of personal experience in how effectively they treat recording and listening rooms.

While working through his diffusor sizes and placements, I realized there was only a tiny selection of commercially-available diffusion products, unless you were willing to build them yourself. There were a few small vacuum-form devices, as well as a range of quadratic-residue / phase-grating products – but there were no effective non-phase-based diffusors on the market.

So I designed a new product lineup consisting of three different-sized cylindrical diffusors (check the Curve System pages for the reasoning behind this), a similar-profile absorber, and a corner trap. I approached Acoustical Surfaces with the concept, they liked it, and the “Acoustic Geometry” brand was launched in mid-2010.

Acoustic Geometry offers diffusors, absorbers, and other acoustic treatments for many different purposes and environments, from recording studios to convention centers to home theaters. We’ll be releasing a new product called the “Voice Curve”, meant to work in the speech articulation range, and we’ve got other nifty products in the pipeline – keep an eye on this space. And please email me with any questions or comments – I’m at [email protected].
