Amina Tech’s SoundUnseen™ Plaster-In-Wall Speakers; For Wall, Ceiling Installs Use NXT Flat-Panel Technology

August 30, 2006

Plaster-In-Wall speakers, a new concept designed to achieve completely invisible home and office installation, using an NXT-patented flat-speaker configuration, will be introduced for the first time in the United States by Amina Technologies Ltd., Huntingdon, England at CEDIA Expo 2006, booth #218, starting September 13, 2006 in Denver. CEDIA is the Custom Electronic Design and Installation Association. High-power vibrational element flat speakers have made possible totally unseen in-wall or in-ceiling speakers which produce high definition sound with no “visual interference” to room aesthetics. Entertainment systems can now be placed in any room in the home without visible wiring or “technoclutter.” The technology offers improved dispersion characteristics over conventional speakers, making location and listening position far more flexible. The new Amina Technologies’ SoundUnseen plaster-in-wall speakers permit homeowners, consumers, decorators, remodelers, specifiers and professional installers to equip high-quality multi-room installations and home theaters without compromising the interior design of modern living spaces. Core element of an Amina Plaster-in-Wall speaker incorporates a specialized strong, lightweight composite material that vibrates in the same way as natural musical instruments, as with the acoustic guitar, violin or piano. The vibrations recreate the diffuse source of sound energy that is emitted in a less directional manner and capable of filling a space more evenly than a conventional speaker. This diffuse source creates a high-definition sound over a very wide area, ensuring that a surround sound or stereophonic sound field can be heard regardless of room size, shape or listening position. Heart of the Amina Plaster In-Wall speaker is its acoustic engine, which can include from one to four (depending on power levels) rare earth, magnet-based, high power vibrational excitation drivers. This allows the Model AIW5 in-wall speaker to handle 80 watts of continuous power, generating 105 db of sound with plaster applied (see specifications below). Amina’s AIW range of speakers cope with the most dynamic sounds, recreating the clarity of individual notes produced by the classical guitar, to the impressive effects generated in today’s action movies. The speaker’s acoustic engine sets up tiny, powerful vibrations in the composite panel material, which are then transferred through the overlaid plaster, paint or wallpaper covering to the front surface of the wall or ceiling. This, in turn, vibrates air molecules at its boundary. These then excite more air molecules further away, sending a diffuse, non-correlated energy sound wave into the room. Width of the new AIW products allows the speakers to fit well within standard 16-inch centers between wall studs for wood or metal construction. Model AIW1 is an affordable, concealed sound source for use in all parts of the home where more modest sound levels are needed. Model AIW3 is designed for main listening areas or home theaters, where good high levels of sound are desirable. Model AIW5 is for the special area of the home where very loud, highly dynamic, high performance sound reproduction is required.
