Man, i compared closed vs normal on crinacle.com . Would prefer closed version.
Please find someone who can measure lcd-2 stock and with your closed kit. Then post results here. If you manage to fix mids and higher frequencies you will become a saint.
Possibly use equalizer built into kefs and boost midrange frequencies where voices are for quiet environments. You actually might target midrange boost similar to what yamaha ns-10 has.
If in his measurements Amir matched harman curve to red line measurement he would get closer to what Oratory1990 got:

Overall, it is the headband that ruins them, not the sound quality.
Great headphone marred by ****** headband. I don't agree on measurements though. For me it is quite close to hd600 in the sense that i dont need to eq both.
Crinacle did excellent research on effects of pad wear:

Hd650 does lose quite a bit of hf with pad wear. While hd600 becomes more balanced.
Because audio purists will argue that any eq or processing deteriorates signal, hence one has to pay more to get something mechanical that one can get electronically. :)
DWM panels are not really for deep bass. They are there for upper bass. If you want deep bass you need the likes of rel, svs, hsu and rythmic (nice with tracking tech)
Man, relax. All this "bad" performance is uber good once you check amplifier performance of amps inside jbl lsr305 amd lsr308, local darlings.
If you are paranoid get a denon x3700, put it in preamp mode and a bunch of power amps. This should allow for pretty much state of the art performance...
I was gonna write some intelligent explanation. But i will just say "because marketing" and all people are different. Only a small number of people will need hf cut due to hearing them bright.
This is such an easy test. Just do it.
This was measured for 305s ( http://noaudiophile.com/JBL_LSR305/ ):
HF switch works as advertised. So if HF is too much just flip it.
It would be really great to see JBL4367. They seem to run circles around Revel in terms of distortion (taken from here https://hometheaterhifi.com/reviews/speaker/floor-standing/jbl-4367-studio-monitor-loudspeaker-review/ ) :
