What it is and who it fits

The HP S100 sound bar mounts directly to the bottom bezel of compatible HP ProDisplay, EliteDisplay and Z monitors from 2017 and 2018. It draws power and audio through a single USB connection so no external adapter is needed. The bar adds dual-speaker stereo output for video calls and media without taking extra desk space.

Limits of the USB-powered 2.5 W design

RMS output is 2.5 W with a 2.8 W peak, so volume is suited to personal listening at a desk rather than filling a meeting room. Frequency response runs from 140 Hz to 20 kHz through an 8-ohm load, meaning deep bass is not reproduced. The line-in jack accepts portable players but adds no amplification of its own.

Tool-free mounting and common snags

Slots on the bar engage the monitor’s lower bezel and a USB cable plugs into the display’s integrated port; no drivers or screws are required. Installation fails when the monitor lacks the matching slots or an available USB port. The right-side volume knob and headphone jack are within reach, but the short captive cable limits placement flexibility.

Questions about this item

Which power rating should I choose between RMS and maximum output?

The bar delivers 2.5 W RMS continuous power and peaks at 2.8 W maximum output, so the single model covers both figures.

What does 2.5 W RMS mean for everyday listening at my desk?

2.5 W RMS provides clear stereo sound for video calls, streaming and multimedia at typical near-field distances without distortion.

What does the USB connector actually power and what limits apply?

The USB connection powers the speaker bar directly from the monitor's port, eliminating an external adapter and drawing only the 2.5 W RMS the amplifier needs.
