Overview
Setting the pair on a desk gives a stereo reference. Each monitor pairs a woofer with a tweeter behind a waveguide and has its own Class-D amplifier, with a Slip Stream port tuned for tight bass.
The reason to consider it is the room controls and balanced inputs, which suit a home studio, together with a waveguide for a wide sweet spot. The limitation is conflicting data, since dimensions and tweeter size are given in more than one way.
Who it's for
Music producers, podcasters and video editors setting up a nearfield desk will use the pair as shipped. Buyers who need wireless streaming or a clean, consistent spec sheet should look at another listing.
Pros and cons
- Sold as a pair
- Image Control Waveguide for wide imaging
- Boundary EQ and HF Trim
- Balanced XLR and TRS inputs
- Dimensions given two ways
- Tweeter size listed in two units
- Several spec fields look wrong
Performance notes
The waveguide shapes how the tweeter spreads sound, which widens the sweet spot, and the Slip Stream port tunes the bass response. Boundary EQ and HF Trim adjust the output for room acoustics. Each monitor has its own Class-D amplifier driving the woofer and tweeter.
