The Invisa Signature Point Source 
GoldenEar Challenges the Status Quo of In-wall Speakers
 
Invisa Signature Point Source (SPS)
 
Over the past couple of years we've been sending out these newsletters while trying to stick with our stated goals of limited sales and marketing content and more general help and information material. In particular we haven't really spent much time talking about our in-wall / in-ceiling Invisa products. At this year's CEDIA show (Custom Electronics Design and Installation Association) we debuted an exciting and dramatic new Invisa model that we feel is very special. Todd Anderson, of AVNirvana.com wrote about the demo experience there:
 
"The entire demo room was filled with a sense of room-widening spaciousness, which wasn't surprising based on my experience with other GoldenEar designs."
 
For those of you who are concerned about high performance and some serious listening in rooms that limit the use of free-standing speakers, the new Invisa Signature Point Source is the perfect answer. And if you're interested in an essentially invisible truly high performance surround sound system the SPS makes a fabulous LCR combined with other Invisa models for surround and height applications to create a complete, virtually invisible, high performance home theater. The SPS is capable of delivering all the dynamics, fidelity, imaging and clarity of our larger Triton Towers when paired with a matched GoldenEar subwoofer (or two, preferably).
 
Like other Invisa models, the SPS features our pioneering "flange-less design" that makes them less visually obtrusive. Additionally we've managed, through careful engineering, to create a smaller footprint than in-wall / in-ceiling models with similar size drivers from other companies. Dimensions are 28-3/16˝H, 8-9/16˝W, 3-1/4˝D without the optional back box. The back box adds ½˝ to the depth. The back box helps to reduce sound bleed to adjacent rooms if that is an issue in any installation.
 
OK, I give, so what's a "point source"?
Most loudspeakers designed for residential use are designed to be a point source. Essentially, it means that the designer has engineered the drivers, their positions on the speaker baffle, the baffle itself and the crossover network with the goal of creating a cohesive, focused sound generator that doesn't act like several disparate elements. Such a speaker would result in smooth, controlled dispersion, superb imaging and consistent sound over a broad area. However, actually creating such a speaker using multiple drivers is easier said than done, even with today's powerful computer programs. The fact is, many speakers only approach a true point source and don't deliver all the performance a point source is capable of. The SPS actually does a spectacular job of emulating a true point source system and exhibits all of those attributes even though it's an in-wall system!
 
Technical Details
The SPS incorporates four 5 1/4˝ high-definition cast basket drivers, very similar to those used in the award-winning Triton One. There's also a full size High Velocity Folded Ribbon Tweeter similar to the ones in the Triton towers. The particularly complex crossover was created using computers and the same fully balanced topology found in our high-end models with a carefully chosen polystyrene film capacitor in the high frequency section. Through careful listening, a unique wiring twist was developed and used to connect all the drivers. It enhances mid and high frequency definition, clarity and detail.
The "works". Impressive, to say the least!
 
The 5 1/4˝ drivers are divided into two sets and each set actually sports different construction and sonic capabilities. Each pair covers a different frequency range, in order to achieve a point source radiation pattern, with the dramatic benefits of better dispersion and improved imaging. The two outer drivers are frequency limited to a maximum of 500 Hz, while the two inner drivers continue up to 3 kHz in order to blend perfectly with the tweeter. All this is precisely accomplished by the driver design differences and the optimized, balanced crossover. The voicing, which is the result of countless hours of critical listening and tuning, is signature GoldenEar; smooth, natural and detailed; without the annoying artificially exaggerated upper midrange and high frequencies often used to cover up the lack of true high-resolution capability.
 
Other Features
There's a front mounted switch to adjust tweeter level, a magnetically attached low profile grille, non-resonant mineral-filled frame structure and special rotating "dogs" for easy and secure mounting. The tweeter can be rotated for correct orientation, either vertically or horizontally. The optional backbox has been engineered with special EVA damping foam internally and open-cell foam externally to reduce sound bleed to an adjacent room. Optional rough-in brackets are available to ease installation in new construction.
 
The sound quality of the Invisa SPS is simply extraordinary: ultra-dynamic, with an open boxless sound that belies the fact that these are in-wall loudspeakers, which of course was our goal. They are capable of producing a huge image with breathtaking height and pinpoint imaging. Retail price of the Invisa SPS is $999 each (US). Price of the optional back box is $149 each (US). Available early Spring 2018.
