I went with Overkill Audio's suggestion, small sealed box.
Here is the response in room at 1m aprox, no filters. Sweep 60-8k.
I have 18" open baffle bellow, crossed at 120hz, and the sealed 12PE32 is crossed at 80hz. LR4. And upper cross point is 1500Hz to DE250 in RCF H100 horn.
It sounds good! Thanks all for suggestions!

Nice one... Glad you like it!
Large Sd (twin 15 inch or single 18 inch) open baffle bass can sound superb....
If you have the space and dont mind the looks it can sound stunning over the n 25Hz up to around 150Hz / 200Hz.
Cheers

IMHO a bigger enclosure and a serie resistor will gives you a far better alignment, allowing you cover one more octave.
You should choose your volume, then choose an alignment and its related Qts.
Here is the formulas in order to calculate Re :
Re=Res/(R0-1)
R0=Qms/Qts

Sorry, it was a bad idea, it will seriously degrade the loudspeaker design performance.
You should keep the small box and stay above 200 Hz.
Edit : i wouldn't use a xover point under 250 Hz (the optimal point is over 300Hz)
