Designed to be used in left, centre or right locations the DC8i brings audiophile performance to both music and movie applications in vast array of listening and viewing environments.
Built around the unique high sensitivity Tannoy Dual Concentric™ drive unit, the Definition Install range brings class leading accuracy, detail and dynamics to installation applications ranging from media rooms to home theatre and boardrooms through to high end marine interiors.
The compact MDF cabinet is vented and rigidly constructed with extensive bracing to be acoustically inert. The unit can be mounted either horizontally or vertically using the integral keyhole mounts and the supplied wall plate.
The speaker is designed to be hidden within a custom designed installation; mounted on wall either behind the screen or acoustically transparent decorative panels with no appreciable loss of performance.
Characteristic of the Dual Concentric™ design is a very wide 'sweet spot' with an exceptionally even response throughout the listening area, as well as an extraordinary transient response; reasons enough for this phase accurate Tannoy designed drive unit to have been the choice of professional studio engineers all over the world for many years.
The Dual Concentric™ is effectively two drivers properly merged into one where, unlike ordinary drive units, the high frequency unit is positioned on the back of the low frequency driver. As a result they are on same axis, so ensuring that sound energy is effectively propagated from the same point and delivered through the centre of the low frequency cone as true point source.
Such integration optimises reproduction quality by providing a constant time delay over the frequency spectrum, exceptional transient performance, wide dispersion and superior harmonic alignment; all of which delivers to the listening position a natural, clean and integrated sound with greatly enhanced intelligibility, sound staging and dynamics.
Tannoy has commissioned NWAA Labs, an independent laboratory providing uniform product testing of loudspeakers and materials to the audio and acoustics industry, to undertake an extensive specification verification programme for its loudspeaker products.
With eighty years experience in the manufacture of loudspeakers Tannoy is justifiably proud of the audio performance of their acoustic technologies, such as the point source, constant directivity Dual Concentric™ driver.
As one of the worlds leading manufacturers of premium quality loudspeakers we are fully confident in our product performance and the veracity of our internally generated specifications and performance data. However, we are delighted now to have established an ongoing working relationship with NWAA Labs; one that enables us to present an independently verified folio of technical data for each product, eliminating the need for this to be repeatedly commissioned by consultants and specifiers across the world.
Unlike any other laboratory in the world, NWAA Labs has the ability to do MACH™ Testing (Multi Angle Computerised High-speed Testing™) to meet ISO and ASTM standards. Based just north of Los Angeles, California, the laboratory facilities include an anechoic chamber and two reverberation chambers uniquely fitted with the MACH™ Testing system.
Led by former NASA design engineer and scientist, Ron Sauro, the NWAA Labs team combines the talents of well-respected researchers, acousticians and consultants to provide unmatched state-of-the-art testing. Well known in the audio and acoustics industry as a consultant and a member of the EASE and EASERA computer software development team, Ron brings over 20 years of field experience to the company.
MACH™ Testing and what it delivers:Originally developed by NASA in 1968 for use in testing the Pioneer, Explorer and Voyager spacecrafts in addition to the manned Apollo lunar program, the MACH™ Testing method has been reformulated into a revolutionary process for evaluating loudspeakers and materials. This cross-pollination of technology from the realm of space research to the world of sound and acoustics research has produced a high-speed testing system unlike any other.
The new MACH™ testing method uses a proprietary array comprised of 19 matched microphones and a precision turntable capable of one tenth degree accuracy. It simultaneously samples impulse responses within an anechoic chamber and uses these to create loudspeaker radiation balloons in a fraction of the time used by other testing methods.
This data is gathered by a multi-channel version of EASERA, using appropriate stimuli, and then is converted to EASE V4, EASE V3, CLF 1 and 2 formats for distribution to consultants and specifiers.
All the EASE and CLF data, plus the certified specification files, can be accessed by going to the main site downloads section or clicking the download tab on this product page.
