I suggest you read this yourself, and what voice coils are, diaphgrams are, and your statement about "different drivers."

Very best,

I consider the driver to contain the diaphragm, voice coil, suspension, etc.
In my eyes the 32, 80, 250 and 600 ohm headphones all contain different drivers. However the only thing we know for SURE that is changed is that that voice coil is varied in its gauge. Even beyer has admitted that this small change makes it sound very different.

Anyways i didn't want this to turn into a terminology war. Sub bass and dt770/80s.
Are the crossfade LPs muddy? how do they compare to the 770s and XB500?

i don't think the 770 pro have very good sub-bass, they can go pretty deep, but eventually roll off, and can struggle with really deep bass. 
 
the denons have much more control, with the d2000 having the most bass, while the d7000 has the most sub-bass while still being loud and controlled.
 
as for the LCD-2, they don't have the same amount of bass as the denons, but it has much more refinement and controlled, and goes far far lower than the denons,

I'd get the D5000. I haven't heard them but I've read enough about them and they are what I'm getting next.

In my opinion, all decent orthos have great sub bass. I owned HE-500 and now have Fostex T50Rp "Paradox" - both models have no problems with super low bass section, but their bass is totally flat (especially on paradox) - there is no spikes or mid bass elevation or smth like that...

The Pro 900 are hard to beat in bass anything

Just to identify a few headphones here:

Looks like it could be a bit bright or hard sounding based on a few of its bumps. It also appears to be more mid bassy. Way too much distortion in the bass area too.

The bass here looks nice (to me) maybe a bit of hardness between 1-2k? Still tempted.

I have these, the bass bleeds into the mids. Boxy sounding, I also dont need this much punch, however i do like a elevated sub bass.

I've read mixed reviews, some about them being bright (maybe the spike around 10khz?) and them not being overly bassy. Bass is elevated in a good spot for me though.

Looks like bass could bleed into mids and spike around 3.2(ish)khz could cause alot of fatigue and perhaps a nasal sounding presentation.

This is the 600 ohm, the 80ohms have more sub bass but still manage to maintain a treble peak.

I've heard these, but have mixed feelings about them. Not blown away for some reason.
 
Where do the 700MKii and Q40 fall in here? Are there any other contenders? The D2000 have a slight boost in the sub bass area but dont output as much as a few of the above. LCD2/3 and Hifiman offerings are flat to below 20hz, but i'm looking for boosted sub bass.

Fact of the matter is, non-orthos WILL have more sub-bass presence, simply because they all have massive sub-50Hz harmonic distortion (most of what you hear in the sub-bass is just distortion).
 
Orthos esp the newer ones will be very linear and extended, as reflected by FR measurements, but they will also be incredibly clean, reflected by THD measurements - which inadvertently makes them sound like they have less sub-bass. Really it is just cleaner sub-bass without huge overloads of harmonic distortion "junk" present in almost all voice-coil dynamic headphones.

I agree with ur generalization with orthos generally having lower distortion in the lower freq. I'm assuming this is also linked to their larger driver size. However you are incorrect with your idea of dynamics. M100, UE6000 and a few other dynamics can contain well executed 40mm or 50mm drivers that have low distortion at extreme sub bass levels (down to 20hz). A post above contains measurements for these cans.

These have too much distortion.

The dx000 series all extend quite low but lack the nessary dip in their response where the ear is most sensitive (4-7khz) this dip is important for a headphone. This causes them to sound hard or almost bright. I've heard the d2000 and d5000, while decent headphones I found them not being for me. Also, their distortion in the sub bass area is bested by considerably cheaper headphones that don't sound quite has hard.

Didnt know that.
Thanks!
That explains quite a bit

For more sub-bass, look at cheaper, purely fun HP's. 
I have both JVC's S600 and DT770 and I can assure you that S600 has substantially more sub-bass. It's overall very nice sounding HP but needs a little EQ bump in mids. 
The more popular S500 probably does not need EQ, but it's on-ear.
 
BTW, I assume you already EQed Beyers as it would be quite stupid (no offence) buying other cans without having listened to what current HPs are actually capable of.

Hi,

Are you getting a tight seal all around the ear with the current earpads on your beyers? If not I'd look into pad rolling to find pads that do, that would make a huge difference in bass extension.

You might also want to take the earpads off to have a look at the driver enclosure to see if this mod applies to your model:
