Compact USB SoundBar for Monitor Mounting

The Dell AC511M is a 2.1 channel stereo SoundBar that draws power and audio from a single USB port on a monitor or laptop. Its 15.9 in plastic cabinet mounts directly to compatible displays, removing the need for separate speakers, a power brick or batteries. Touch controls on the unit handle volume and mute without extra software.

Steady Output at Low Power

Rated at 2.5 watts, the SoundBar maintains consistent stereo output during long work sessions or video calls without thermal throttling or distortion. The passive dynamic drivers and 20000 hertz upper frequency limit deliver clear mid-range and treble for voice and system sounds, while the USB bus power keeps the signal chain stable.

Replaces Freestanding Desktop Speakers

This unit upgrades from bulky wired speaker pairs that occupy desk space and require an AC outlet. The jump is worth it when a single USB port is available and a tidy, monitor-mounted audio solution is preferred. It does not suit users needing deep bass, room-filling volume or wireless connectivity.

Questions about this item

How much heat or noise does the AC511M produce when powered from a USB port all day?

The soundbar draws 2.5 watts from the USB port, so it adds very little heat and has no fan or moving parts to create noise during extended use.

Which USB port must my monitor or laptop provide for the AC511M to work?

A single standard USB Type-A port supplies both power and audio signal; no separate power adapter, driver installation or battery is required.

Will the 15.9 in AC511M attach to the monitor I already own?

An included mount clips the 15.9 in x 1.5 in x 1.9 in bar to the bottom of compatible Dell monitors, leaving your existing desk space free.
