Slim magnetic sound bar for Dell monitors

The Dell SB521A attaches magnetically to compatible Dell displays and draws power from a single USB-A connection. Stereo drivers deliver 3.6 W RMS output across a 180 Hz to 20 kHz frequency range. The design suits office workers who want clearer calls and alerts without desktop clutter.

Consistent output during long sessions

Because the bar is USB-powered, its amplifier runs within the port’s current limit, so volume stays steady during extended meetings or playback. The 180 Hz low-end cutoff keeps bass distortion low when the system is pushed for hours. No external adapter means one less heat source behind the screen.

Tool-free magnetic mount with security loop

The speaker snaps onto the monitor frame in seconds and moves freely with tilt, swivel or pivot adjustments. A 0.15 m USB cable routes behind the panel for a clean look. The included security loop accepts a user-supplied lock to deter theft in shared spaces. No drivers or batteries are required.

Questions about this item

How loud does the 3.6 W RMS sound bar get when it runs all day?

The 3.6 W RMS output is designed for desktop listening at close range; it stays cool because it draws power only from the monitor's USB-A port with no external supply.

Which monitor port must I already have for the USB cable to work?

A free USB-A port on the back of the monitor is required; the 0.15 m cable plugs directly into it for both power and audio.

Will the magnetic mount still hold if I keep using my older Dell monitor that can tilt and swivel?

Yes, the bar snaps magnetically to compatible Dell monitors and moves with them through tilt, swivel and pivot adjustments.
