delta 12 lf 4ohm version really good if you like punchy bass got them in my tl5050's and they sound good x-over at between about 51-55 hz -  250 hz did have them at 410 hz to give a bit more mid, but only when i was running 18xb's under them, hope this could be of help.

At 50hz a direct radiator box of the same net size will have 10dB more output.

The horn will have more output in the 300hz~400hz region.

If you want to try different drivers in Hornresp
Cut-Off Frequency=50hz (hyperbolic-exponential T=0.6)
Throat Area=81 sq. in.
Length=53 in
Mouth Area=769 sq. in.
Front Cavity=130 cu. in.
Rear volume=1.7 cu.ft.

Original EV driver (two 12s)
Fs=45hz
Qms=9.5
Qes=0.215
Qts=0.210
Vas=5.06 cu. ft.

"Hm, LAB12's looks nice, but, they have very low sensitivity :/ "
 
Not in a horn, they don't.

"Any sugestions about another 12" sub bass drivers?"
 
The mouth of a TL5050 is tiny, don't expect sub bass out of it no matter what driver you put in it.

That's suspect as well- the Sp12C was a fullrange driver was it not? I think something like one of the DLs would be better.
Away on extended leave.
