Try using the NEUSCH 18 inch driver distributed by Kolin Electronics. looks very similar to the Void 18 1000.  u can request from them the thiele small parameters cause its not being posted on their site.

i have a friend who has NEUSCH drivers inside 186 horn, modified the rear chamber a little. (slightly reducing rear chamber volume) produces chest thumping bass and high fidelity low end.

here is their site...

The 1850 has a larger voice coil and can handle double the rated 800w for years on end. It moves more air > huge linear travel.  Its just better suited for the 1850 Horn in every way. Thats why its called the'1850 Horn'.
Stick the C18-650 in the 186. It wont be as loud as the 186, but will probably piss on most of the cabs you can build for the same price when it comes to SPL. Build four, plug them into something like a CA12 [at least] and sit back and enjoy. Thats what I still want to get to do.....

what do you think of this driver in 1850 or 186 box?

RCF LF18N401 here are some preferences


THIELE - SMALL PARAMETERS
Resonance frequency Fs 32 Hz
DC resistance Re 5.1 Ohm
Mechanical factor Qms 6.5    
Electrical factor Qes 0.27    
Total factor Qts 0.26    
BL factor BL 27.8 T - m
Effective Moving Mass Mms 201 gr
Equivalent Cas air load Vas 257 liters
Effective piston area Sd 0.122 m2
Max. linear excursion (mathematical) Xmax 8.8 mm
Voice - coil inductance @ 1kHz Le1k 2.5 mH
Half-space efficiency Eff 3.01 %

 
I'd put that driver in the 1850 design cab.
 
I think it will sound really good. The Vas is a bit higher than the PD1850 which is a good thing. The RCF's does not have such a powerful motor system and so will have a bit more low bass and less kick. All things that should make it sound really good in the 1850 horn.
 
Rog.
