Bang & Olufsen Beosound Theatre 55 Gold Soundbar

Bang & Olufsen Beosound Theatre 55 Gold Soundbar

This listing covers the Beosound Theatre soundbar in the Gold configuration designated 55, the size class Bang & Olufsen optimises for 55-inch class televisions. The audio product itself is the same Theatre platform: an active soundbar with twelve custom drivers, 800 watts of amplification and integrated Dolby Atmos decoding, presented in a gold finish. Because Theatre is configured around a chosen screen using specific wings, interfaces and mounting hardware, the 55 designation describes the intended screen pairing of this configuration rather than a different loudspeaker, and the listing itself presents the product as a soundbar.

Key features

• 12 speaker drivers with two custom 6.5-inch woofers and a coaxial centre channel for clear dialogue
• 800 W of amplification producing up to 112 dB SPL from a single bar
• 7.1.4 Dolby Atmos decoding built in, with True Image upmixing for non-Atmos material
• RoomSense setup with a supplied microphone for level, distance and resonance compensation
• System expansion for up to 16 external Bang & Olufsen loudspeakers in wired and wireless combinations
• Gold finish in the 55 configuration listed for 55-inch class screen installations

One bar, full multichannel decoding

The driver complement mirrors the standard Theatre layout: two 1-inch tweeters, four 2.5-inch full-range drivers, two 3-inch midrange units, a coaxial centre made from a 5.25-inch midrange and a 1-inch tweeter, and two 6.5-inch woofers driven by dedicated 100-watt amplifiers. Side-firing and up-firing drivers work with beam width and beam direction control to place surround and height information around the room. The rated frequency range of 28 Hz to 23,000 Hz and a bass capability figure of 94 dB SPL explain why the bar can carry film effects convincingly on its own, while advanced bass management keeps low frequencies controlled at higher levels.

Set up around your room

RoomSense measures the installation with an external microphone and adjusts speaker level, distance, position compensation and low-frequency room resonances automatically. EQ presets in the Bang & Olufsen app can be customised, and the top panel’s proximity-sensitive controls handle everyday adjustments. Over HDMI the bar accepts Dolby Atmos sources including Dolby TrueHD, Dolby Digital Plus 7.1 and Dolby MAT, plus multichannel PCM 7.1 and AAC formats, so a television’s eARC output or a connected player can feed it the highest quality soundtrack available.

Streaming and multiroom

When the screen is off, Theatre works as a music system in its own right. Apple AirPlay, Spotify Connect, Chromecast built-in, TIDAL Connect, B&O Radio and Deezer are supported, and Beolink Multiroom links it with other Bang & Olufsen products around the home. Dual-band Wi-Fi handles network streaming and Bluetooth 5.1 covers direct playback from phones and tablets, with SBC on Android and SBC or AAC from iOS devices.

Planning the 55 installation

The soundbar itself is 122.2 cm wide and weighs 18 kg, standing 19.7 cm high on its table stand or 18.9 cm high on the close wall bracket. Bang & Olufsen offers screen interfaces, wings and stands matched to particular televisions, and the Theatre platform is optimised for screens from 55 to 77 inches, so the exact wing, interface and mounting parts for a given television should be confirmed against that screen’s measurements before installation.

As listed, this is the Gold Beosound Theatre in its 55 configuration: a twelve-driver Atmos soundbar with room calibration, streaming and surround expansion, sized as the audio partner for a 55-inch class television setup.
