Under the surface are 11 individually powered speakers, including two five-inch woofers, two midrange drivers, two tweeters, and five “full-range” drivers. The collection includes both side-firing and upfiring drivers to bounce sound off your walls and ceiling for surround sound and 3D audio formats like Dolby Atmos and DTS:X.

Around back, you’ll find solid connectivity, including HDMI eARC/ARC for seamless connection to modern TVs, an HDMI passthrough port for connecting a streamer or gaming console, Ethernet, RCA analog connection for a legacy device like a turntable, and a traditional subwoofer that lets you side-step Marshall’s available wireless sub. There’s no optical port, but since optical doesn’t support Dolby Atmos or DTS:X spatial audio, that’s kind of a moot point.

Setup is pretty simple, but the bar’s hefty size adds some complications. At three inches tall, it’s a tough fit beneath many TVs. Conversely, the rubber feet that diffuse its 43-inch long frame from your console offer almost zero clearance at the sides and, unlike bars like Sony’s Bravia Theater 9 or System 6, there’s no way to extend it. That makes it tough to set the bar down properly with all but the thinnest pedestal TV stands, which are becoming common even in cheap TVs. All that to say, there’s a good chance you’ll need to mount your TV to use the Heston.

Like the Sonos Arc Ultra, there’s no remote, meaning adjusting settings mainly relies on the Marshall app. The app is relatively stable, but it froze up during a firmware update for me, and it usually takes a while to connect when first opened. Those are minor quibbles, and your TV remote should serve as your main control for power and volume.

Wi-Fi connection unlocks music streaming via Google Cast, AirPlay, Spotify Connect, Tidal Connect, and internet radio stations, with Bluetooth 5.3 as a backup. Automated calibration tunes the sound to your room (complete with fun guitar tones), and in-app controls like a multi-band EQ provide more in-depth options than the physical knobs.

The Heston 120’s sound profile impressed from the first video I switched on, which happened to be an episode of Bob’s Burgers. The bar immediately showcased a sense of clarity, openness, and overall definition that’s uncommon even from major players in the space.
