Exciter X 25-4 Ohm - Surface Sound Transducer

The Exciter Type X 25-4 Ohm is a tactile transducer that transforms almost any hard surface such as wood, glass, or metal into a loudspeaker. When ideally placed, you get invisible sound with amazing sound quality. Connected to the surface – you can now listen to music without conventional loudspeakers via suspended ceilings, walls, and existing furniture. There are no limits to your imagination here.

Advantageous Installation Options

Due to your room concept - for reasons of space or aesthetics - you prefer not to see any loudspeakers? Then our tactile transducer from our "Invisible Sound System" category is perfect for you: simply attach the Exciter to the desired surface such as ceilings, walls, furniture, cabinets, cabinet doors, and counters. Whether kitchen fronts, side panels of cabinets, or plinths - even glass fronts, mirrors, as well as projection surfaces and whiteboards are transformed into loudspeakers by WHD-Exciters. Through hidden and optimal placement, you get an invisible and exciting sound. For more details for product manufacturers, see the video.

Using the self-adhesive foil already applied upon delivery, our "invisible loudspeaker" can be horizontally attached to many different surfaces, which then serve as a resonance body. Vertical placement can also be achieved by screwing it on. With our positioning aid, you can playfully determine the ideal position for attaching the Exciters, so that you achieve amazing sound quality despite different surfaces such as wood, glass, or aluminum.

In public areas, the listed installation options can offer protection against vandalism. In areas where climatic conditions play a role, our tactile transducer can be optimally placed and hidden, so that heat, cold, humidity, dust, and other influences do not have to pose difficulties. Even in rooms with the highest hygienic requirements where conventional loudspeakers are out of the question, our resonators/exciters still offer a music experience for relaxation, motivation, and concentration.

Considering its dimensions, this Exciter can be easily installed in small and narrow installation locations.

Surprising and Amazing Sound Quality

The X 25 tactile transducer impresses with its shallow installation depth. The values for sound pressure level, frequency range, and beam angle depend on the material used. Depending on placement and material, you get impressive sound reproduction that is sufficient for background music.

Easy Combination with Conventional Systems

Like normal loudspeakers, Exciters are connected to the sound system via cable. They can be connected to low-impedance amplifiers, as well as to conventional sound sources with loudspeaker connections. For amplifiers with a loudspeaker impedance of 4 ohms, one X 25-4 Ohm can be connected per channel. The nominal/music power handling is 5/8 watts.

We recommend a combination with our Bluetooth/WLAN receivers BTR 405, BTR 405 LV, WR205, and WR250 DSP. By discreetly installing the complete sound system, you get a modern and "invisible" sound system from which the internet's music world can be heard from smartphones, tablets, and laptops. Transform everyday areas and objects into an innovative music system.

Modern Music Listening through Invisibility

Enjoy the beautiful world of music through our "invisible loudspeakers". You will be amazed at how good the environment can sound. Everyday objects like furniture are instantly transformed into loudspeakers. No more standing loudspeakers and no annoying cable clutter. Nothing disturbs the ambiance - but as if by magic, the room sounds amazingly good. The invisible sound technology inspires: pure musical enjoyment that you hear but don't see.
