David Crewe - SoundCrewe Founder & Designer

SoundCrewe Audio was founded in 2009 by David Crewe, a mechanical engineer and master wood craftsman with strong creative genes and a lifelong love of music. David’s father held degrees in both art and engineering, and passed his love of building things down to his son. David followed in his father’s footsteps, working for a decade as an engineer before deciding to leave the industry for another love: building furniture. He honed his craft in a 2500-square-foot workshop that he and his father built years ago. Looking to bring his creations to an even bigger audience, David, his wife, Keeli, and a fellow furniture craftsman, Rudd Montgomery, launched area 61, a gallery and showroom  in the historic and revitalized Southside district of Chattanooga, Tennessee.

The gallery’s initial location in the middle of Chattanooga’s exploding local music scene, as well as the emergence of high-end audio component suppliers, rekindled David’s long-time interest in speakers. He spent hours online researching and exchanging questions and ideas with fellow audiophiles on audio discussion boards, eventually designing and producing his first pair of speakers. But true artists are never satisfied with their work, and David would spend years of studying, designing, measuring, building, and rebuilding until finally arriving at a design that rivals any speaker being produced today.

While David has always emphasized sound quality that meets the expectations of the serious audiophile, the aesthetic and craftsmanship of his designs sound out of this world without looking like something from outer space. The unique style and finishes appeal to audiophiles and non-audiophiles, alike, blending high-end hifi with functionally artistic home interior design.

Visit area 61 gallery - in its new downtown Chattanooga location, next door to the historic Tivoli Theatre - to listen and experience SoundCrewe audio and commission a pair of your own.

The Shape


The shape of SoundCrewe audio speakers is based on sound wave technology and is integral to the design.

The Shape


The shape of SoundCrewe audio speakers is based on sound wave technology and is integral to the design.

A sphere is the most sonically transparent enclosure, as it allows sound waves to grow around it without being influenced by any reradiating surfaces. The exterior of the enclosure is spherical well past the horizontal equator before being tapered toward the rear. By the time the waves reach the taper, they have lost a good deal of their energy and the waves that are reflected are directed away from the listening position.  

The interior of the enclosure follows much the same path as the exterior. Internal waves are directed to the rear port, which has been vented in order to eliminate the reflection of waves back to the cone, thus eliminating distortion. 

The enclosures utilize a solid, dual-layer wood construction consisting of an outer layer of hardwood and an inner layer of soft wood. The dual layers, combined with a wall thickness that varies from ¾” to more than 1 ½”, offer little chance for any resonance frequencies to influence the enclosure. 

CUSTOMIZATION
We can fully customize any speaker set. Our speaker enclosures and bases can be constructed using virtually any available hardwood. We’ve custom designed a vast array of stain colors to choose from that can add a splash of color to any room, or we can create other stains and finishes to specifically coordinate with your environment.

 

“David has melded the desired sound with the perfect blend of form and function to develop a speaker that looks as slick as it sounds. SoundCrewe speakers represent the ever-elusive mix of aesthetics and function, and their dynamic design echoes the function of the speaker to produce a clear, smooth response. They are more remarkable for their clean reproduction of sound than any consumer speaker I’ve heard.”

Crew Chief for Bonnaroo and Firefly music festivals

COMPARISON BETWEEN SPHERICAL ENCLOSURE (LEFT) AND TYPICAL BOX SHAPED SPEAKERS (RIGHT)

While these drawings are not based on any type of specific data, they do represent in general terms how waves are diffracted off of the enclosure walls – showing that they are uniform and symmetrical. As sound waves expand outward from the driver in a spherical fashion, the advantages of a spherical enclosure become clear. In typical loud speaker design,  the diffraction is reradiated in more concentrated directions with an abrupt drop at the edges.

Currently in the loudspeaker industry, the trend is to add more drivers to the equation thus exacerbating the destructive effects of the accumulated diffractions.  While rounding edges softens the diffractive loss drop, most of the diffraction is still evident.

So, why aren’t there more speakers built like ours?  This type of enclosure is difficult and expensive to mass produce.  For those who want uncompromising sound, SoundCrewe is built for you.
