Frequency response
Not available yet. Add a real measurement (1/6 octave smoothed, gated, on-axis) here once you have one for this build.
Ideal use case
A desktop speaker addon, or an assisting sub for bookshelf speakers that could use a bit more low end. Also suited to Hi-Fi studio monitor setups at reference-level volume. Not built for loud playback, but it can work for low to mid-volume living room listening, just don't expect it to get very loud.
Sound
Flat, Hi-Fi grade bass, tuned for accuracy over impact. Reaching down to 32Hz is genuinely impressive for a cabinet this size, which is what makes it a solid pick for reference monitor use rather than just background thump.
