The JBL Bar 300 is a one-piece soundbar that handles movies, shows, games and music from a single spot below your TV. Its MultiBeam processing and Dolby Atmos decoding aim to spread effects around the room without rear speakers, which suits apartments or living rooms where extra boxes would be a hard sell.

Total output is rated at 260 watts, and the built-in bass port is there to add low-end punch without a separate subwoofer. We'd consider this a sensible pick if you want a cleaner setup than a bar-and-sub combo allows, but we'd skip it if you expect the physical rumble a dedicated sub delivers.

The room and routine that make this a good fit

A compact bar works best in a small to medium room where you sit fairly close to the screen. PureVoice dialogue enhancement is designed to keep speech clear even when surround effects are busy, which helps if you watch a lot of dialogue-heavy shows at modest volume.

At $299.95, this sits about 15 percent below the typical price over the last 90 days of $352.59, and 239 ratings average 4.1 stars. That makes it a reasonable value if one bar must cover TV and music, but pass if you want true rear-channel separation or deep subwoofer bass.

Measure the space under your TV and confirm the bar fits with your stand or wall mount, then check whether your room's size and seating distance match what one bar can fill.

From source to room

From source to room: Dolby Atmos and MultiBeam processing suit a compact TV setup, while 260W and a built-in bass port cover everyday movies and music without a separate sub.
