Use existing objects, furniture, and surfaces to create sound with our technical Bluetooth master solution!
With our BTR405 Exciter Set, consisting of a 230 V Bluetooth receiver and 4x Exciter X32-8 Ohm, each with a 1m speaker cable length, you now get an invisible and exciting sound. Connected to the surface - you can listen to music without conventional loudspeakers via 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 or aesthetic reasons - the Bluetooth system and 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 4 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 desired cavity.
Whether kitchen fronts, cabinet side panels or skirting boards - even glass fronts, mirrors, as well as projection surfaces and whiteboards become loudspeakers thanks to WHD exciters. Using the self-adhesive film already applied on delivery, our "invisible loudspeaker" can be glued horizontally to many different surfaces, which then serve as a soundboard. Vertical placement can also be achieved by screwing. With our positioning aid, you can playfully determine the ideal position for mounting 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 placed and installed covertly in such a way that heat, cold, moisture, dust or other influences do not pose any difficulties. Even in rooms where the highest hygienic requirements prevail and conventional sound systems are out of the question, our covertly installed sound system offers a musical experience for relaxation, motivation and concentration.
The X 32-8 Ohm body sound transducer impresses with its very good bass reproduction. The values for sound pressure level, frequency range and radiation angle depend on the material used. Depending on the placement and material, you get impressive sound reproduction that is sufficient for background music.
Through 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 such as 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 BTR405 Bluetooth receiver has a range of 10m, which ensures a stable connection between devices and guarantees interference-free sound reproduction. Thanks to the already connected 1m speaker cables to the included sound transducers, we guarantee flawless signal transmission.
Our Bluetooth system is perfectly designed for background music and has a low energy consumption of 36 watts. The four included 8 Ohm exciters are each supplied with an amplifier output of 5 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 already 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, and setting of the max. volume, multiple BTR 405/BTR 405 LV units can be used within range. This makes this Bluetooth sound system ideal not only for homes and offices, but also for 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 individually naming the Bluetooth receiver, you get the correct assignment. Listen to music from the bathtub and relax to the fullest. With background music in your sauna, you can clear your mind from everyday life and let your thoughts run free. Also, enjoy music in the kitchen anytime while you prepare dinner to the fullest.
