Initial impressions

The DK-4001 seems to be tuned relatively neutral but also has its quirks and colourations. There is a suppression of the upper midrange which diminishes the “bite” of female vocals and brighter-leaning brass instruments. There’s a relatively prominent lower-mid treble emphasis as well, but this emphasis is not within range of cymbals or claps.

I’d say that the strongest point of the DK-4001 is the bass response. Hits are clean, there’s no midbass bloat and there’s a well-controlled sub-bass focus. Rumble comes through well-articulated and doesn’t detract from any other part of the frequency response as a whole.

Imaging sounds about average, nothing much to say. The stage doesn’t diffuse outward too far and there’s a slight claustrophobia in the placement of the instruments. Not a particularly strong choice for live recordings for my money.

And of course, the measurements:
