FlexiBooth’s potential uses are anywhere from conventional to literally “off the wall.”

FlexiBooth ($399) is an acoustically absorptive vocal booth in “cupboard” form. It is designed to hang on the wall of your audio workspace. Closed, its casing — made of black melamine-coated MDF (medium-density fiberboard) — measures 2 feet wide, 4 feet high, and a bit over 5 inches deep. With both 4 x 1-foot doors open, the FlexiBooth becomes a 16- cubic-foot VO environment.

Two years ago, I reviewed Primacoustic’s Broadway Series of acoustic products during a complete refurbishment of my primary audio workspace [full article available here: 18244 — Ed]. That installation continues to be the most significant pro audio investment I have ever made.

So naturally, when presented with the opportunity to review the FlexiBooth — primarily comprised of the same high-quality absorptive materials as the Broadway Series — I was intrigued. While it is primarily marketed as a wallmounted vocal booth, its potential uses are anywhere from conventional to literally “off the wall.”


FlexiBooth’s absorptive components are highdensity (6 lb. per cubic foot) encapsulated fiberglass panels with resintreated panel edges, covered with acoustically transparent polyester fabric in black, gray, or beige (which can even be covered with a second fabric to better match or to develop a unique décor, if so desired by the user). Three panels — two 46 x 9.75 x 1 inches on each door and one 46.75 x 22.5 x 2 inches in the middle — provide the absorptive zone of an open FlexiBooth. [Detailed absorption characteristics of FlexiBooth are available on the Primacoustic website at www.primacoustic. com/flexibooth-specs.htm — Ed.]

Completely unconstructed, the FlexiBooth comes with numerous parts: the three panels, seven MDF pieces, and several bags full of cam locks, wooden dowels, screws, pins, dry wall anchors, etc. Also enclosed are two door guides, four door hinges, and two magnetic door catches.

Last but not least, accurate and wellillustrated assembly instructions are included, featuring diagrams and photos.

In Use

Of course, before I could place the FlexiBooth in use, I had to build it. With basic tools (Phillips head and flathead screwdrivers, small hammer, power drill, and level) and an extra set of hands, the FlexiBooth was together and hung in place with well under two hours of labor invested, even working at a relaxed pace.

Once constructed, I screwed the FlexiBooth’s mount — a French cleat — on the rear wall of a small editing/control room (with tie lines to other recording spaces throughout a large residential structure). In this position (placed between an entrance door and closet door), the FlexiBooth (when open) would double as an adjustable absorptive surface behind the mix position and a VO space, maximizing the functionality of this small audio production room. In both applications, FlexiBooth excelled.

Since FlexiBooth can be easily lifted off the beveled edge of its wall cleat, I also used it as a “gobo” in front of acoustic instruments, amplifiers, drum kits, etc. The back of the FlexiBooth exposes most of the rear of its nearly 2 x 4-foot Broadway panel, so additional absorption was gained in any “off the wall” application. It’s also worth noting that, when closed, the FlexiBooth becomes a hard, reflective surface; the idea of several FlexiBooths mounted around a room in varied positions of open, closed, and somewhere in between would allow lots of sonic options.


As the name was conceived to imply, FlexiBooth is indeed very flexible, thus making it much more than just an acoustic product for tracking vocals. It’s attractive, clever, useful, and much more than the sum of its parts.
