Sonos vs JBL: a single 9.1.4 bar built to grow, against a 7.1.4 system with a sub and rear speakers in the box.
Updated 2026
Verdict
Buy the JBL Bar 1000MK2 if you want real rear surrounds and a 10-inch wireless sub included, so you get surround sound out of the box. Buy the Sonos Arc Ultra if you want a single elegant bar with Sonos multi-room streaming that you expand later with a Sub 4 and Era 300 speakers.
