JBL Bar 1300XMK2 Review
A muscular, highly immersive flagship with unusually flexible rear speakers and first-rate bass authority.
At a Glance
The detachable rear speakers are the defining practical advantage: they provide genuine surround when needed and dock back onto the bar afterward. Add the large subwoofer and strong high-volume performance, and the system suits rooms that want cinema impact without permanent rear-speaker installation.
