Tannoys say on the iw4dc In-wall dual concentric wideband speaker.

The Tannoy iw4dc is a full bandwidth in wall speaker system, using a 100mm Tannoy Dual Concentric point source, constant directivity drive unit, designed for installation into standard stud partition wall systems. It may also be used in cavity wall installations constructed with standard thickness drywall as well as a wide range of other wall construction types with a surface thickness of up to 25mm.

This compact unit is specifically designed for applications requiring the combination of premium sonic quality for music and speech reinforcement and exceptional reliability and intelligibility.

Advanced technical features on the Tannoy iw4dc In-wall dual concentric wideband speaker

The driver and passive frequency dividing network are mounted in an injection moulded, paintable front baffle manufactured from UV/weather resistant UL94V-0 ABS material.

The class leading performance is further enhanced by the inclusion of four self aligning, spring loaded clamps; allowing for quick install but also for simple removal or reorientation of the loudspeaker. The rigidity of the clamps and baffle combination crucially provides the acoustically optimum bond to the wall surface without risk of distortion to the baffle itself. Complementing any style of decor, the perforated metal grille and discreet moulded baffle can be painted to blend seamlessly with any environment.

Gold plated spring loaded terminals are provided for ease of installation and a steel back can is available as an optional installation accessory.

Other Key features about the Tannoy iw4dc drive unit.

The Tannoy Dual Concentric drive unit comprises a multi fibre paper pulp mid bass cone and a 19mm ferrofluid cooled, titanium dome HF unit with neodymium magnet system.

The mid-bass and tweeter sections of this constant directivity driver are coincidentally aligned to a true point source; ensuring a wide and controlled dispersion for optimum coverage; this while avoiding the massive loss of energy, in the vertical plane at the crossover frequency, inherent in two-way discrete designs.

Featuring a wide bandwidth frequency response and very low distortion, the iw4dc is also equipped with dynamic high frequency protection.

Testing on the Tannoy iw4dc In-wall dual concentric wideband speaker through NWAA Labs

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.
