Most sources call the low end lean: a sub-bass shelf with little mid-bass body, fast and clean but short on slam, weight and decay. A minority — mostly listeners who wanted a planar without the usual bass bloat — like exactly that politeness. Nobody calls it a bass-forward set.
“There isn’t much slam, and the kick and floor tom of the drums lack a sense of depth beyond the initial impact.”

“It’s got satisfying planar driver speed but it often feels watered down and lacks impact.”
Prime Audio Reviews (David Becker)
“Personally I am a fan of the whole low end of the Dioko, at least as far as tuning goes, but I can see others wanting a little more warmth in these lower ranges.”

36 squig.link rigs agree to within a decibel: sub-bass on the Harman IE 2019 target at 20 Hz, but 1–2 dB under it from 40 to 100 Hz and back to level by 200 Hz — a shelf that lives below 100 Hz with no mid-bass lift at all. Taping the front vent adds only 1.6 dB at 20 Hz.
