bass impact would be slam, not quantity, so pressure is the key, closed cans have an advantage, but on my rig my lcd2 have enough slam to impress even the most hardcore bass heads ,what is not a surprise if you take in account the size of the driver and the amount of excursion, which likely makes it the can with most slam ever
this is true, cancels the dominating bass quantity, but should rise slam on capable rigs as well, lcd2 need good rms with a lot of peak power reserve
another thing is that the lcd2 is extremely linear unlike most closed cans, which are L or U shaped so the slam is more distributed and doesn't peak in a narrow lf region
lcd2 needs a powerhouse
Yes indeed pressure is the key which is why most (but not all) closed headphones excel in because the soundwaves are reflected off the inner housing and back into the listener's ears, nonetheless the bass from the LCD's are still impressive considering they are open as hell and still can do sub-bass low end rumble very well, but as you described this is no surprise considering the size of the driver.
But heck even when I just need bass sometimes with bass dial's on maxed out 5db's the bass isn't enough, this is being powered on taps by a Marantz PM-32 amp with upped mA on the 4 transistors for MOAR POWAH and SOUND TRANSIENTS. Best bass-impact headphone I have heard to date is my modded HD438's, volume cannot be upped too much otherwise distortion from the driver which you can literally see the coil and membrane pump up and down, they are for my other level of electronic music (hardcore, darkcore, industrial/experimental and dark dnb).
I really do like my LCD's for metal though, sounds great with the djent and progressive stuff. Get's me drunk faster as well as I usually drink here and there when I listen to music. Gotta love Balkan made rakija, something you're very familiar with roskodan.
