Tannoy Dual 4" In-Stair / Stage Front Speaker System iS52

Engineered for highly intelligible music or speech reproduction in houses of worship, theatres, auditoriums, performance venues and a host of other applications, the slim enclosure design uses two 100mm (4.00") low frequency and two 25mm (1.00") high frequency drivers mounted behind a kick-proof grille. Primarily designed to fit neatly into stair risers or stage fronts between standard 16" studs, the iS52 In Stair loudspeaker is in fact suited to a vast array of sound reinforcement applications. As a full bandwidth loudspeaker they will deliver a high quality sonic performance, with a smooth and controlled response, for an exceptionally even coverage pattern and optimum forward gain. Coupled with the enhanced efficiency and extended response from the twin 25mm (1.00") titanium dome, neodymium magnet system high frequency units, the two 100mm (4.00") mid bass drivers provide high mid-bass output from what is in fact a very small enclosure. The robustly constructed, black painted plywood enclosure has a removable kick-proof grille of black powder coated, perforated steel. Both the grille and the enclosure are paintable to suit the install decor.
