Should I replace my e12a with an 2 e10o's or 1 e15a ?


This really seems to be a misconception here guys.
One thing we probably need to make more clear is all of our drivers are simply built for Sound quality. No one really any more than the other.
The thing that really dictates which is best isn't really SQ or SPL wants. It's just simply application.
K, Sealed, vented.
O, Larger sealed. IB
A, Sealed, vented.
Inherently due to the applications we recommend them in the O's just do not have and will not have the thermal power handling of either of the other two drivers. One reason I think you'll see so many people running them with lower power.
There really isn't a tonal SQ difference between the lines, just more of a is this right for my application difference.
How much power are you currently using / will be using in the future?

"Which setup will give the best sq (tight bass) and low end ?"
The e10o is very impressive with its low end frequency reproduction while at the same time being very transient (able to keep up with drum beats) and musical. The e10o doesn't "hit" as hard as a more SPL type speaker (Kicker L5), but it is a great SQL sub, proably the best I've heard. And you don't have to spend $$ and deal with the hassle of a JL10W7.
Even though 2 10" subs have slightly less surface area than a single 15, they will give you more transient bass, more of a "kick you in the chest" feel, and still achieve the sub 30 Hz range.
Unless you listen to mostly rap music where a 15 will give you that "low level vibration bass", it just doesn't reproduce typical rock/pop/country music the way it should be reproduced. There is too much of a "gap" between your 6.5" mid bass components and a huge 15" sub.
If space were not an issue I'd always go with 2 10" first, then a single 12", then a single 10", in that order.
A single 15 playing an 80 Hz test tone sounds "different" than 2 10's playing an 80 Hz test tone.

In a similarly aligned box with the same amount of output it should sound the same.
