Increasing demand for integrated lifestyle-technology combined with the associated ‘aesthetic-clutter’ that it brings has led to a rise in hidden technology solutions. With 30% of brain power dedicated to visual stimulus and only 2% dedicated to audio, it is clear that the way we ‘see’ the sound has a huge impact on the way we perceive it. By removing the aesthetic aspect, it allows complete focus on the audio art-form as it was intended.
How does it work?
With the invention of VPT (Vibrational Panel Technology), Amina has been able to take the common loudspeaker design and replace the cone with a flat panel. Instead of moving forwards and backwards visibly like a typical cone design, a VPT panel uses small vibrations to generate sound which can be heard but not seen. This allows for seamless integration of a loudspeaker into any wall, ceiling or flat decorative panel with zero visual impact.
Derived from an experiment in immersive audio by the British Ministry of Defence in the early 1980s, Vibrational Panel Technology allows a loudspeaker cone to be replaced by a flat panel. This creates a complex series of ‘tuned’ surface vibrations which generate acoustic energy. This is very similar to the way in which an acoustic musical instrument works.
Unlike a conventional loudspeaker cone, VPT loudspeakers generate what is known as an incoherent-phase waveform. This means that the acoustic energy generated by the panel interacts in a summative way with the room reflections, leading to an incredibly smooth room-filling sound rather than the typical hot spots and tonal colouration associated with direct phase correlation. The bass response from these invisible speakers is quite phenomenal when you consider the technology behind the sound but if you prefer deeper bass response, try the awesome kick of the ALF series of in-wall subwoofers.
With a complex array of vibrations and associated incoherent-phase waveform, a VPT loudspeaker has the incredible benefit of full 180° audio dispersion. This means that whether you are stood directly underneath an Amina loudspeaker, or on the opposite side of the room, you will experience the exact same sound quality. Unlike a conventional loudspeaker, the location of Amina in-wall speakers are usually very hard to place and quite deceiving at times. They have a great WOW factor when entertaining guests.
It is a myth that invisible loudspeakers are limited in audio performance. The general assumption is that by being positioned behind plaster or other finishing material, the speaker sounds ‘muffled’. This is just not true and has to be experienced to be believed. The loudspeaker works with the covering material to generate incredible detail and clarity. With advancements in panel materials, Amina loudspeakers can also produce incredible bass or as mentioned earlier, simply add an ALF in-wall subwoofer or a free standing avtive subwoofer such as the M&K V8 or Jamo J10SUB, also available from Radionic.
Amina invisible loudspeakers are designed to be installed into a variety of materials such as dry wall, solid wall, ceiling boards, wood, leather etc There are 2 series available depending on the installation and substrate :
For installation into drywall, a completely invisible plaster up-to loudspeaker that provides ultimate audio performance.
For installation into a range of materials such as wood, leather and wet plaster skim, giving the ultimate in design and installation flexibility.
For more information on Amina, download the full catalogue below or contact the Radionic sales dept to arrange a demonstration. There is usually a rotating Amina demo board at one our authorised Amina retailers and there is an active in-wall and plastered over set of Amina at the Radionic showroom in Brakpan.
