Try your real numbers
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
It needs 55.3 inches of width with its detachable speakers docked, more than your 48 inches.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.
Sonos, Arc Ultra
Choose the Arc Ultra when you want a single bar now and the option to add a Sonos subwoofer and rear speakers later. It needs nearly 47 inches of cabinet width and uses your TV for source switching.
JBL, Bar 1300XMK2
Choose the 1300X MK2 when rear-speaker outlets are the obstacle to a complete surround setup. Three direct HDMI inputs simplify a busy TV, but the detachable speakers bring a charging routine and the subwoofer is substantial.
