Some of the Complex Design Elements in GoldenEar Enclosures
Our enclosures are built using internally braced MDF making for a fairly "dead" cabinet. Building a totally inert enclosure is next to impossible and would be very expensive which would defeat our above stated prime goal. So we ensure that any remaining enclosure resonances have minimum sonic impact on the speaker's using a variety of methods. These include tapered walls which reduce internal standing waves, strategically placed custom open cell foam absorbers, accelerometer optimized bracing and more, several of which are detailed below.
The rounded front of the Tritons is formed by a strong expanded metal curved grille under the cloth. The metal has thousands of relatively large perforations that allow the sound pressure waves to pass through unimpeded. In fact, they also work in some ways that help to improve dispersion. So the drivers are protected and are open to deliver an almost 180-degree sound field in the mids and highs. Bass frequencies inherently wrap around the enclosure, are impervious to edge diffraction (more below) and are relatively un-localizable.
The exceptionally narrow side to side aspect ratio of the Triton enclosures and the resulting narrow front baffles reduce the negative impact that a wide front baffle can impart. If you ever wondered why we use a "racetrack" format for the Triton woofers, this is a primary reason. Their narrow cross sections allow us to achieve the narrow front baffles which are so essential to minimize diffraction and optimize imaging. (There's more about this in the following article.) As a side benefit, these narrow baffles make the Tritons quite unobtrusive in the room.
The midrange and HVFR tweeter drivers are isolated from the woofers within their own internal, sealed sub-enclosure. Each midrange is within its own different-size enclosure and the HVFR has a sealed back which isolates it from the rest. This eliminates any negative impact the rear pressure waves from the powerful bass drivers could have on the mids and highs. These sub-enclosures also brace the larger enclosure panels, helping to reduce resonances.
The Triton (and Aon) Infrasonic Radiators are mounted opposite each other on the enclosure sides in an inertially balanced configuration and as they pulse in equal but opposite directions they self-cancel potentially harmful low frequency panel vibrations and cabinet movement.
All these factors are key to the exceptional detail, imaging and clarity without fatigue you experience when listening to a GoldenEar speaker. Sandy and the design team have managed to create exceptionally efficient and inert enclosures that help deliver performance that "punches way above their weight range" at prices just about anyone can afford.
So, although many GoldenEar speakers appear to the untrained eye to simply be elegant looking, they are in fact, superbly well engineered and totally in keeping with our goal of superb performance typically found in systems costing far more.
