Tannoy IS-52 Brochure

iS52 In-Stair

Product Description

Designed for a wide variety of sound reinforcement applications, Tannoy’s new In-Stair

loudspeaker fits neatly into stair risers or stage fronts between 16” studs. Engineered for

highly intelligible music or speech reproduction in houses of worship, theaters, auditoriums,

etc., the slim two-way design uses a twin 4” low-frequencer driver and twin 1”

high-frequency configuration behind a kick-proof grille. A full bandwidth loudspeaker

designed for high quality sonic performance, these speakers provide a smooth and

controlled response for even coverage and optimum forward gain .

Dual 100mm (4") low-frequency drivers provide high mid-bass output in a small enclosure ,

while the twin 25mm (1") high-frequency units have titanium domes and a neodymium

magnet system for enhanced efficiency and extended response.

The black painted finish plywood enclosure has a removable black powder-coated, perfo-

rated steel kick-proof grille. Both the grille and the enclosure are paintable. A separate

steel backcan is included which allows for use in concrete or where a metal enclosure is

required. This backcan has multiple conduit knockouts for installation versatility.

Features

• Unique design allows mounting in stair risers or stage

fronts, or other installed applications

• 120° horizontal and 90° vertical controlled dispersion

for optimum coverage and forward gain

• Kick-proof powder coated steel grille
