This set - consisting of the WR 250 DSP Wi-Fi receiver and 2x QB 300 WL wall speakers - transforms any room into an impressive experience zone. With the Bluetooth/(W)LAN receiver WR250 DSP, you can listen to music from many apps from end devices such as smartphones, tablets, laptops, and computers in excellent Hi-Fi sound quality on the high-quality and powerful QB300 WL design speakers. The WR 250 DSP contains a 2x50W stereo amplifier with an integrated DSP (Digital Signal Processor) and can be easily hidden, e.g., behind a plasterboard ceiling, due to its small size. The QB 300 WL speakers from WHD stand for the highest sound enjoyment in the best quality: Very high-quality, compact, and modern high-end speakers in an aluminum design that guarantee the best possible sound.

The WR 250 DSP receives music, e.g., from a smartphone or tablet, via the WHD Multiroom Player App (Link to video) or via any music apps using AirPlay*, DLNA or UPnP and plays it through the connected speakers. The music streaming receiver can be operated via the Ethernet socket, Wi-Fi, and also via Bluetooth. Connect the two included QB 300 WL surface-mounted speakers to the WR 250 DSP via speaker cable and hide the audio receiver in cavities such as ceilings, walls, furniture, behind mirrors, cabinets, and counters. As soon as the connected 24V 5A power supply receives power, music streaming can begin. An external sound source such as a CD player can also be connected to the Line-In.
Due to the many music providers in audio streaming, you get the ideal music for every business to enhance the stay of customers and guests. When used in boutiques, experience stores or gourmet shops, the customer's impulses to buy are released due to the feel-good atmosphere and they might stay in the store longer. A stylish and high-quality sound system in reception areas, wellness rooms, beauty salons and much more makes the customer feel valued and well taken care of, so that they can enjoy it to the fullest. The acoustic experience can contribute to inviting repeat visits and recommendations.
WHD designs its speakers as carefully as a top chef plans a Michelin-starred menu. The result: Pure high-end enjoyment that takes these 2-way speakers to new spheres. The characterful result produces an ideal sound even in the lowest frequency spectrum. Thanks to bass reflex, the QB 300 WL offers a precise and soft bass for its size, even in unusually deep regions. The harmonically rounded 4-inch long-throw woofers and fabric dome tweeters guarantee remarkably clear and clean sound reproduction. With only 30 watts of power, you get a first-class, superior, and intense sound thanks to the perfect coordination of the design with the acoustics and the harmonious dispersion. Enjoy the warm and rich high-end sound at any volume!
A proprietary algorithm has been developed for the DSP chip, which dynamically adapts the sound in the loudspeaker. This technology, WHD Adaptive Sound Plus, ensures, among other things, that the listener experiences high-quality sound even at low volumes. 3 presets can be selected: Neutral, Loudness, Extra Bass.
The two Hi-Fi speakers not only boast exceptional and intense sound quality but also feature a timeless and elegant design. Thanks to its minimalist design, the QB 300 WL always blends into any environment and thus suits all furnishing styles – whether modern or rustic. The special lacquer gives the compact speaker a slightly rough surface, providing tactile feedback with every touch.
Whether an exclusively furnished establishment in a residential building, guesthouse, hotel, or practice – the compact speaker makes a creative contribution with its high-quality, discreet, and elegant design. Best of all – it also offers an ultimate sound experience that will amaze you and everyone else.
Using our free WHD Multiroom Player APP, you can also select music programs from Deezer* and integrated internet radio stations. Thanks to the MemoRadio function, your station playlist with your favorite stations is immediately on air after switching on the WR250 receiver, without the need for a smartphone or tablet.
An optionally available KNX gateway can control the WR250 and other WHD (W)LAN devices – such as the WR 55, WR 205, the Qube (XL), and the AirBridge Pro. For example, a KNX can be used to select an internet radio station that is played directly by the WLAN module. No smartphone or tablet is required for this. Furthermore, the volume can be controlled and the module can be switched off via KNX.
As an extension, you can set up a multiroom system by using other WHD (W)LAN devices in the vicinity. All devices such as the WR 250 DSP can be controlled via our free Multiroom Player APP.
