Dual 2.0 speakers for compact desks

The SOULION R90 is a 2.0 desktop speaker system that fits on narrow shelves. It delivers 6 watts total power from two dynamic drivers with a 4 ohm impedance. The gray cabinet measures 2.9 in x 12.7 in x 2.9 in and weighs 0.558 kg. It suits users who want basic stereo sound without a subwoofer.

USB power plus aux or Bluetooth input

A single USB connection supplies 5 volt power while a 3.5 mm auxiliary cable carries audio. Press the M button to swap to Bluetooth mode and pair a phone or tablet. Four LED lighting modes cycle with a short press of the light button; a three second hold resets the Bluetooth link. The rotary knob adjusts volume in either mode.

22000 hertz top-end frequency response

The published frequency response reaches 22000 hertz with a 50 decibel signal to noise ratio. Buyers who need deeper bass extension or higher fidelity for critical listening should note the limited low-frequency specification. No external power adapter is required beyond the USB port.

Questions about this item

Will the 6 watt amplifier or the 4 ohm drivers need servicing as the speaker ages?

The solid-state amplifier and dynamic drivers have no user-serviceable parts; keep the USB power and 3.5 mm aux connectors clean and the unit should run for years without internal maintenance.

What stops the soundbar from playing louder during a long gaming session?

The 6 watt RMS limit per channel and 50 dB signal-to-noise ratio cap output before distortion rises, so sustained peaks are clamped by the built-in amplifier ceiling.

How warm does the 5 volt USB-powered chassis get and will the LED lights add noticeable fan noise?

There is no fan; the low 5 volt supply and 6 watt total power keep the enclosure barely warm to the touch, and the LEDs run silently with no audible hum.
