Memorex MX-SB270 Soundbar vs Dell AC511M Stereo Soundbar

Buy the Memorex MX-SB270 for a TV in a living room or bedroom. It is a 27.5-inch, 24W 2.0 bar with HDMI ARC, optical, aux and Bluetooth, plus a remote, wall mount and five EQ presets. The Dell AC511M is a 16-inch, 2.5W USB-powered bar that clips to a Dell monitor stand and is built for desk use, not TV sound. Owners of the Memorex describe basic but usable TV audio; the Dell is widely liked as a cheap way to add sound to a monitor, but it is quiet and has no HDMI.

  • Choose the Memorex MX-SB270 if you want one bar under a TV with HDMI ARC, optical input, a remote and enough power for a room.
  • Choose the Dell AC511M if you want a small USB-powered bar that mounts on a Dell monitor stand and clears desk clutter.

What reviewers say

Dell AC511M Stereo Soundbar

Owners treat it as a practical upgrade over monitor speakers for office work and video calls. Most praise the tidy under-monitor fit and easy setup, while criticising the weak bass and low maximum volume.

What people mention
  • Sound qualityMixedOwners say it beats built-in monitor speakers for speech but sounds thin on music.
  • BassCriticisedReviewers note very little low end, so bass-heavy tracks fall flat.
  • VolumeCriticisedThe 2.5 W amp is fine at a desk but too quiet for a room.
  • MountingPraisedThe under-monitor bracket keeps the desk clear and puts sound at ear level.

Questions and answers

Which is better for a TV?
The Memorex. It has HDMI ARC and optical inputs, a remote and 24W of output. The Dell AC511M is a 2.5W USB desk bar with only a 3.5mm input, so it is a poor match for a TV.
Which is better for a desktop PC?
The Dell AC511M. It runs off USB, clips to a monitor stand and keeps the desk clear. The Memorex is over a meter wide and needs AC power, which is awkward on a desk.
Does the Memorex support Dolby Atmos?
No. It is a 2.0 system with no Dolby Atmos or surround decoding. The Dell is also plain stereo.
Can I use the Dell soundbar with a non-Dell monitor?
It works as a speaker through the 3.5mm or USB connection, but the mounting bracket is made for Dell monitor stands. On other monitors you would set it on the desk.
Is the Memorex worth stepping up to over the Dell?
Yes if the bar is for a TV or a larger room. The extra power, HDMI ARC, optical input and remote make it the more capable speaker. Stay with the Dell for a monitor setup.
