The JBL Bar 300 MK2 is a 5.0-channel soundbar that creates virtual Dolby Atmos height effects without rear speakers or a separate subwoofer. Its 450W amplification and built-in bass ports give it more low-end punch than most all-in-one bars, and MultiBeam 3.0 widens the soundstage so off-center seats still hear effects. It suits small to mid-size rooms and renters who want cinematic sound with minimal clutter. Against bars that ship with a subwoofer, it gives up some true sub-bass depth, but it is simpler to place and works with any TV brand.

Owners of JBL all-in-one bars generally praise the wide sound and surprisingly strong bass for a bar without a subwoofer, and note clearer dialogue than flat TV speakers. Some say the virtual Atmos effect is subtle and that deep bass still falls short of a system with a real sub.
