I don't think the neutrality would change if there was a little bit more volume below 37hz or so. The fourth driver doesn't need to change the FR either, just help with bass impact and rumble.

My point is-- there's a product for people who want enhanced bass-- The Ultimate Ears Personal Reference Monitors. The standard UERMs are tuned for accuracy. You can get enhanced bass through the listener-tuned personal model.
ADDED: The UE 11 Pros have your 4th driver. I would plead with UE not to mess up a perfect product for those who require neutrality.
I think the UERM is just fine as it is. The additional bass leads me to believe it may be a JH13 but I won't know until the weekend when I pick up them up from my audiologist.

I don't think you're quite understanding me here... So i'll just say that I enjoy the UERMs the way that they are, but of course there can be improvements with just about any product.

I get the sense thegunner100 feels the UERM lacks sub-bass extension.. not that it needs the sub-bass boosted (which is what reeltime is interpreting his comments to indicate, I think).
I've got both the UERM & JH13 FP.. and I find them complimentary enough to share a place in one's collection.. while both maintain a relatively neutral character. The JH13 has a "downward sloping," Olive-Welti-inspired tuning.. the UERM's tuning feels more DF-inspired. The UERM is certainly brighter.. but it rarely, if ever, feels harsh, uneven, peaky, or unnaturally bright. I've found myself becoming very sensitive to treble tuning.. more specifically, I desire linearity and evenness in the treble (not necessarily a shelved down, rolled off treble).. and the UERM delivers that better than most any "bright sounding" IEM or custom IEM I've heard. The UERM reminds me of what I wished the RE272 (an IEM I loved.. but found lacking bass extension, texture, and impact.. midrange body.. and it had some slight treble "un-evenness" issues, to my ears) sounded like.

The downward slope thing is not Olive-Welti inspired tuning. It's been around forever in audio engineering and some speaker building circles. It's true that Olive's recent research has confirmed that a downward slope (of about 10db according to his studies) is ideal / desirable. The extent of this slope is debatable with some studio guys preferring 6db. That includes me. (A 10db slope is way too laid back sounding for me.)
Olive-Welti did come up with a compensation curve for their headphone measuring coupler which translates to this "ideal" curve.
The UERM was based on the Yamaha NS10. That's a fairly forward slightly brightish sounding studio monitor where audio engineers used to argue about how many layers and what brand of toilet paper to put over the tweeter. I am not kidding about this.
As for the subbass extension issue, use EQ to boost bass at 30Hz a few db. It works.
If you don't like bright, use EQ to tame the treble. That works too.
The good thing about the UERM is that it has a smooth and coherent sound signature, so EQ works very well.

What I'm saying is the custom earbuds gunner is asking for already exists in 2 different products, the UEPRM (Personal Reference Monitor) and/or the UE11 Custom, which has a 4th driver, and extends bass.
Why mess up what is already a great, flat set of monitors (in the UERM), when what you're looking for already exists? Make sense?
Capitol Records engineers spent a great deal of time and effort helping UE produce a flat set of monitors for people who work in the field. It's a tool many of us have come to rely on.
One big reason I want the UERM is the other half of his statement. Smooth (but not smoothed over) and coherent. It's one if the few things I agree with him on
The tuning is... I hope someone got a raise.
It's probably the most coherent sounding multi driver IEM I've heard. I wish I dreamed about it.

I'll probably order the JH13 Pro FP if they do a good Black Friday promotion. I think there are some recordings that are obviously mastered with a bit more bass boost. In the meantime the EQ in the AK120 pumped up a bit in the 35Hz range sounds pretty darn good for those tracks.
And frankly I don't think I have a great seal. Compared to the universal demo pair mine have a touch less bass.
