Overview
Switching between DJ and Production modes, these powered desktop monitors drive a woofer and tweeter from a built-in amplifier. RCA and mini-jack inputs take a controller, mixer or laptop, and the front panel carries a headphone socket and level knob.
The built-in amplifier means no separate power stage is needed, and the mode switch retunes the sound for mixing or studio work. The cabinets are small, so low end has limits in a big room.
Who it's for
Laptop producers and controller DJs working at a desk get a matched pair with a headphone socket on the front. Anyone filling a hall, or wanting a wireless link, should look at a larger or Bluetooth-specific system.
Pros and cons
- Powered pair with built-in amplifier
- DJ and production sound modes
- RCA and mini-jack inputs
- Front headphone socket and level knob
- Small woofer limits low-end output
- Wired-only and Bluetooth entries conflict in listing
- Cabinet weight unclear for a pair
Performance notes
A small woofer and tweeter in a fiberglass cabinet suit near-field listening at a desk. The mode switch changes the tuning between DJ monitoring and flatter production work, and the level knob sets volume without a trip to the software.
