SDL400M-BT, silver - Bluetooth loudspeaker for stretch ceilings

Stretch ceilings, light ceilings, and mirror walls are a very special solution for interior design. With WHD's Stretch Ceiling Loudspeaker series (SDL), their potential is fully realized: high-quality sound, custom-fit, and
inconspicuously installed. The overall design remains undisturbed - and the room sounds!

The SDL 400M-BT is a powerful master loudspeaker with an integrated Bluetooth amplifier, specially developed for invisible installation behind stretch ceilings. With an impedance of 8 ohms and an innovative crossover, it delivers natural and clear sound despite the coverage by the ceiling film. Equipped with a 4-inch woofer and a tweeter, as well as integrated bass reflex technology, it impresses even in the bass range with an extremely flat design height of only 58 mm.

The integrated amplifier offers a power of 2x 5 W, allowing you to conveniently stream music from your smartphone via Bluetooth. In addition, 3 more SDL 400-S loudspeakers can be easily connected to the SDL 400M to create an even more comprehensive sound experience.

Hidden Installation 

Thanks to its flat design, the loudspeaker completely disappears behind the stretch ceiling.

High-quality Sound

The bass reflex technology and the crossover ensure excellent sound, even in the bass range.

Optimized Crossover for Stretch Ceilings 

Specially tuned to make the sound clear and natural despite the cover.

Easy Installation 

The loudspeaker can be easily and securely attached with dowels and screws. For optimal sound distribution, correct placement is crucial, which can be coordinated with the WHD project planning team. This ensures that the loudspeaker is not only perfectly mounted but also ideally positioned to achieve the best sound experience. The distance between the stretch ceiling and the loudspeaker should be at least 2 mm. The stretch ceiling must not rest directly on the loudspeaker.
