TANNOY iw4DC In Wall Speaker ลำโพงฝังผนัง 4 นิ้ว 240W @ 8Ohm
The Tannoy iw4 DC is a full bandwidth in wall speaker system, using a 100mm (4") 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”).
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.
