Utilize existing items and make objects, furniture, and surfaces resonate with our technical Bluetooth master solution!
With our BTR405 Exciter Set, consisting of a 230 V - Bluetooth receiver and 2x Exciter X32-4 Ohm, each with a 1m speaker cable length, you now get invisible and exciting sound. Connected to the surface - you can listen to music without conventional speakers through suspended ceilings, walls, and existing furniture. Enjoy your favorite music from your smartphone, tablet, or laptop via Bluetooth without having to see the sound system.
Do you want to listen to music wirelessly via Bluetooth, but due to your room concept - for space reasons or aesthetic reasons - the Bluetooth system including the speakers should not be visible? Then our powerful Bluetooth receiver BTR 405 in combination with the exciters from our "Invisible Sound System" category is perfect for you: Attach the 2 included surface transducers to the desired surface behind ceilings, walls, mirrors, cabinet doors, furniture or even in counters and install the audio receiver in the respective desired cavity.
Whether kitchen fronts, side panels of cabinets, or plinths - even glass fronts, mirrors, as well as projection surfaces and whiteboards become speakers through WHD exciters. Thanks to the self-adhesive film already applied at the time of delivery, our "invisible speaker" can be glued horizontally to many different surfaces, which then serve as resonators. Vertical placement can also be achieved by screwing. With our positioning aid, you can playfully determine the ideal position for attaching the exciters, so that you get astonishing 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 Bluetooth system can be perfectly placed and hidden, so that heat, cold, humidity, dust or other influences do not have to pose difficulties. Even in rooms where the highest hygiene requirements prevail and conventional sound systems are out of the question, our hidden sound system offers a musical experience for relaxation, motivation and concentration.
The X 32-4 Ohm body sound transducer impresses with its very good bass reproduction. 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.
With simple Bluetooth pairing and handling, you can listen to the music world of the internet or from the internal and external memory of a device. Stream music from many popular music apps like Spotify, Deezer, SoundCloud, AppleMusic, YouTube, Amazon Music, TuneIn, Napster, TIDAL, or listen to your playlists from your hard drive. With our free "WHD Multiroom Player" app, over 1000 integrated internet radio stations can be played.
The Bluetooth receiver BTR405 has a range of 10m, which maintains a stable connection between devices and ensures undisturbed sound reproduction. Thanks to the 1m speaker cables already connected to the included sound body, we guarantee perfect signal transmission.
Our Bluetooth system is perfectly designed for background music, which also has a low energy requirement of 36 watts. The two included 4 Ohm exciters are each supplied with an amplifier output of 10 W. Despite the low amplifier output, a very good acoustic performance is reproduced, which is completely sufficient for background music and ensures low power consumption. Due to the integrated stereo amplifier, no further amplifier is required.
Thanks to the additional settings via our Android app "BTR Configuration": assignment of Bluetooth name and access PIN, as well as setting the max. volume, multiple BTR 405/BTR 405 LV can be used within range. This Bluetooth sound system is therefore not only ideal for homes and offices, but also in public areas such as waiting rooms, receptions, and hotel rooms. In addition, our Bluetooth system is suitable for mobile applications such as caravans and boats, and is certainly a great asset in campsites and holiday villages in the respective mobile homes, chalets, and lodges.
If you have a BTR405 Exciter Set in the bathroom, sauna area, and kitchen, all devices within range can be recognized by your smartphone, tablet, or laptop. By assigning individual names to the Bluetooth receiver, you ensure correct assignment. Listen to music from the bathtub and relax completely. Background music in your sauna helps you clear your mind from everyday life and let your thoughts roam freely. Also, enjoy music in the kitchen anytime while preparing dinner to the fullest.
