Heinrich's WS15/T is a wall-mounted loudspeaker with a built-in 70V/100V transformer. The 70V/100V transformer technique reduces line losses over long distances and makes parallel connections of multiple loudspeakers simple. With its built-in 4"+ 1.5" speakers, it delivers a wide frequency response from 120Hz to 15KHz. Its RMS power output of 15 watts makes it suitable for most applications. In addition to the black grille, the ABS enclosure and stainless mounting bracket are made of stainless steel. Easy and secure wall mount installation through the supplied mounting bracket. Suitable for commercial and industrial applications in hotels, schools, shopping malls, offices, and factories where background music and paging are needed.

All HEINRICH speakers are compatible with EASE, CATT, and ULYSSES models for acoustic studies. By simulating sound quality and distribution, the acoustic model can be used to determine how well the installation will work. A test procedure has been implemented to ensure that HEINRICH loudspeakers comply with the LOW VOLTAGE DIRECTIVE (BS EN 60065, 2003) and EMC regulations (BS EN 61000-6-Part 1/2/3/4).
