iw4 DC
Product Description
The Tannoy iw4 DC is a full bandwidth in wall speaker system, using a 100mm (4.00")
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 (1.00”).
The Tannoy Dual Concentric™ drive unit comprises a multi fibre paper pulp mid bass cone
and a 19mm (0.75") 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 iw4 DC is also
equipped with dynamic high frequency protection. 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.
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.
