Invisible Stereo


"SURROUND SOUND FOR THE 21st CENTURY"

"YOUR ENTIRE ROOM BECOMES A SPEAKER"

NO MORE HOLES, GRILLS, OR CABINETS TO BE SEEN ! YOUR WALLS AND CEILINGS THEMSELVES PRODUCE THE SOUNDS OF MUSIC AND THRILLING HOME THEATER !

OK.., JUST WHAT IS ANYWAY ?

I'll BET !  EXPLAIN HOW THAT CAN WORK ?
Invisible Stereo uses the back half of a speaker assembly, the magnet and voice coil, and sends frequency waves across the room side surface of the wall or ceiling, creating accurate, sympathetic resonations up to 8 feet in diameter. It just does a bigger, better job of producing sound than a much smaller speaker !

Think of the wall surfaces in your home as larger, thicker versions of a speaker cone or drum head. It doesn't take much to transmit sound by knocking on a wall; ask any apartment dweller. Audio has caused more problems than it has solved over the years, acoustically speaking. Speakers, by their design have to push or beam sound frequencies into a room. But the more sound you push into a room, the more it bounces around (standing waves) or is absorbed into the room's furnishings.

  • Worse yet, often non harmonic vibrations of room components can be heard at high volume levels. ( rattling the windows and china, shaking the walls and floors, we've all heard it happen before! )
  • Unlike speakers, that by design focus their energies on creating high Sound Pressure Levels (SPLs)within a room to provide "presence", INVISIBLE STEREO creates large areas of resonating sound. When the room itself is sympathetically resonating, with no standing waves to bounce around, even a "Beyond the Theater" system with 20 Transducers in 5 arrays of 4 Transducers each played at shocking levels, you can still talk to and hear the person beside you!!

WHY INVISIBLE STEREO INSTEAD OF SPEAKERS ?

  • In the years since the reproduction of sound advanced beyond the cylinder/gramophone stage to using a Transducer (magnet/voice coil) assembly and various designs of diaphragms, cones, horns, enclosures, etc.; the size, cost, and appearance of the speaker itself has often been it's own worst enemy. Big speakers sound great but cost allot of money and take up space. Smaller varieties cost less (usually) but just don't create the sensation of "being there"!

    Expensive designs often incorporate multiple drivers in large or tall cabinets of a "free standing" type. Less expensive varieties offer smaller enclosures or "in wall" designs. Both types often do nothing to foster an esthetic appearance despite claims to the contrary. Sound is invisible to the eye yet the methods we use to create sound are anything but. Forward thinking companies and designers try to disguise or conceal speakers or create bizarre cabinet designs to make them (speakers) a work of art worthy of exhibition. At the price your going to pay for such innovative thinking, you should be able to drive them to work!

    And of course, there arises the problem of acoustics. Both speaker and room come into play here. Large rooms mean big speakers, standing waves, reverberation, and usually Big Bucks! Small rooms offer less space for placement, poor separation and imaging, and therefore some compromise in performance quality. Ideally, audio purists seek speakers with a flat freq. response, non-directionality, and an efficient "dB to watt" level. Very few speakers have it all together and the ones that do are usually out of reach for most mortals; space and budget concerns put a brake on a lot of dreams.

    Today, with the enormous upsurge of awareness and demand for Home Theater encompassing the entire spectrum of humanity, there comes a need for the proverbial "chicken in every pot" speaker system. A system that can offer quality at an affordable price for the "every man", yet have almost unlimited design and performance potential for the "high end enthusiast"! Unfortunately though, all of the above is in conflict with todays' prevailing marketing concepts and the reality of todays' current speaker designs. Excepting, of course, a product that has been hanging around for 85 years or so................,
