There’s a reason so many home theater setups still lean on the JBL Bar 9.1 True Wireless Surround with Dolby Atmos years after its release. It squeezed genuine surround sound and height-channel effects into a system that doesn’t demand a single speaker wire running across your living room floor. That convenience comes at a cost, though: wireless rear channels, a wireless subwoofer, Atmos processing, and a Wi-Fi connection all have to stay in sync at once, which gives the system more moving parts than a basic two-speaker soundbar.
