Loewe Klang Bar 3 MR Soundbar - Ex Display

The Loewe klang bar3 mr sits at the heart of Loewe's klang audio range, occupying the position of a fully featured, single-unit soundbar that integrates directly with the brand's television lineup. Launched in 2023 to coincide with Loewe's centenary year, the klang bar3 mr is designed to work in seamless partnership with Loewe TVs from 43 inches upward, though its connectivity suite ensures compatibility with any modern television. It builds on the foundation of the standard klang bar3 by adding the "MR" designation — which stands for Multiroom — bringing with it Loewe's proprietary WDAL 2.0 wireless technology for loss-free, latency-free expansion into larger multi-channel and whole-home audio configurations. Within the klang range, the bar3 mr sits above the two-channel klang bar1 mr and below the more expansive klang projector mr, offering a 3.1-channel configuration with Dolby Atmos processing and a substantial 360-watt total power output from a compact, single-bar enclosure.

Driver Array and Amplification

The klang bar3 mr houses nine drivers within its 950mm-wide enclosure: seven front-firing speaker units and two integrated subwoofers. The front array handles the left, centre, and right channels alongside height processing for Dolby Atmos virtualisation, while the twin subwoofers manage low-frequency reproduction without requiring a separate cabinet. All nine drivers are individually amplified, with the total system power rating of 360 watts providing substantial headroom for dynamic material. The dedicated centre channel is a notable inclusion at this price point, designed to anchor dialogue to the screen rather than allowing it to collapse into the stereo image — a common shortcoming in two-driver soundbars. The result is a 3.1-channel architecture that delivers convincing separation between speech, music, and effects within a single slim unit that stands just 68mm tall.

Surround Sound and Audio Processing

The klang bar3 mr carries full Dolby Atmos certification alongside DTS:X, DTS Virtual:X, and DTS-HD decoding. Dolby Atmos and DTS:X are passed natively from a source via HDMI eARC, with the soundbar's processing engine creating a virtualised height and width soundstage from the front-firing driver array. DTS Virtual:X extends this capability to non-object-based content, applying spatial processing to conventional 5.1 or stereo sources. For music and high-resolution audio, the bar3 mr supports Hi-Res Audio playback, with a frequency response of 50 Hz to 20,000 Hz. HDR passthrough covers Dolby Vision, HDR10, and HDR10+, so 4K HDR video signals routed through the soundbar reach the display without degradation.

Wireless Expansion with WDAL 2.0

The "MR" designation is defined by Loewe's Wireless Digital Audio Link 2.0 technology, which enables the klang bar3 mr to be expanded modularly into a full 5.1 home cinema system without cables between the soundbar and additional speakers. WDAL 2.0 is a proprietary wireless audio protocol operating without audible latency and without lossy compression, distinguishing it from Bluetooth-based expansion schemes used by competing products. Within seconds of pairing, klang mr1, klang mr3, or klang mr5 wireless speakers can be added as rear channels, and a supplementary subwoofer can be incorporated for deeper bass reinforcement. The system also supports open standards for connection to third-party active speakers, Loewe's klang 5 or klang 9 floor-standing speakers, and even legacy Loewe Individual Sound System components with active subwoofers. The multiroom capability extends across up to 16 speakers simultaneously using DTS Play-Fi, enabling whole-home audio distribution from the same unit.

Connectivity and Streaming

The klang bar3 mr provides three HDMI connections in total: one HDMI eARC output for connection to a compatible television and two additional HDMI inputs for source devices such as a Blu-ray player or games console, with 4K signal passthrough on all HDMI ports. A single optical digital input accommodates older source equipment or televisions without ARC capability. A 3.5mm analogue input is also provided. On the wireless side, the bar3 mr integrates Apple AirPlay 2, Google Chromecast built-in, and DTS Play-Fi, enabling direct streaming from smartphones, tablets, and computers without an additional streaming device. Bluetooth is supported for straightforward pairing with mobile devices. Wi-Fi connectivity enables access to streaming services directly from the soundbar, including Amazon Prime Music, Deezer, Napster, Qobuz, Spotify, and TIDAL. Voice control is supported via Amazon Alexa and Google Assistant.

Design and Installation

The klang bar3 mr measures 950 x 68 x 160 mm and weighs 5.9 kg — compact enough to sit beneath a 43-inch or larger television without obscuring the screen or dominating the furniture. The low-profile 68mm height is a deliberate engineering choice: it keeps the bar below the bottom edge of most television panels while allowing sufficient internal volume for the twin subwoofer chambers. Premium materials are used throughout the exterior, consistent with Loewe's approach to domestic product design across its television and audio ranges. The unit is available in Basalt Grey. A remote control is included, and the bar is designed to integrate with Loewe's television operating systems for unified remote control when paired with a compatible Loewe TV.
