Score: 82/100
LG Sound Suite H7
Score: 82/100Rankings
The Sonos Arc Ultra provides premium 9.1.4 Dolby Atmos sound with 14 drivers, Bluetooth 5.3, and integrated voice assistants. Its premium price and lack of detailed EQ may deter budget-focused buyers. Perfect for Sonos users wanting high-end performance in a single bar.
The LG Sound Suite H7 is a premium 9.1.6-channel wireless soundbar featuring Dolby Atmos FlexConnect and AI-driven room calibration. Its drawbacks are the sizable footprint, lack of native voice control, and the need to purchase optional rear speakers and subwoofer for full performance. Best for LG TV owners with large 65"+ displays who want a scalable, high-resolution Atmos experience.

Professional reviewers praise the Arc Ultra as a clear step up from the original Arc, highlighting its richer driver array, Sound Motion bass technology and the ability to deliver high volume without noticeable compression. The soundbar's support for Dolby Atmos and a wide range of wireless protocols, combined with TruePlay room correction, earns it high marks for versatility. However, critics note the lack of any graphic EQ or granular tone controls and the limited low-frequency output of the built-in subwoofer as notable drawbacks.
Professional reviewers commend the H7's expansive driver array, AI-driven calibration and flexible FlexConnect expansion, noting it delivers cinema-grade Atmos sound that rivals wired setups. However, they caution that its considerable size, lack of voice control and the need to buy optional rear speakers and subwoofer may deter some buyers.
Everyday users praise the bar's impressive soundstage, deep bass and easy wireless connectivity, especially the convenience of the companion app. Recurring complaints focus on the bar's bulkiness, the extra cost of optional expansion modules, and occasional dependence on the app for optimal performance.
