Undecided on a design

Hey I have 2 RCF LF18X400 and i want to build two single box that will sound good and hit your chest in a hall. I was going to use the RCF ESW1018 plan or the mini scooper 18. I heard a lot of great reviews for the rcf esw1080. Can anyone help me out?

What kind of speakers do you plan to use above these?
And how low do you need them to go. In my opinion none of the designs you suggest is optimal for chest hitting (kick).

Your drivers should work very nicely in my SV186BPH. But with only two of them there will not be much useful output below 60Hz.

I actually want to build 2 single bass box that will sound great in a hall but i really dont know what plans to use.

Does the size of the box matter to you? What are you going to be using for tops?

Yes the box size matter. Im trying to downgrade in size. I have 4 super scoops and 4 vega folded horns already so im trying to stay away from those big box.

I want the box to be about 36" in height. I will be using 2 rcf 12" or 15" for mids (Not sure of which size yet) with 2 rcf 2" compression drivers.

Aren't the C Vega horns 36" high though? Why don't you make some more of them? Or are you trying for something for small gigs where the sub will take a top-hat, then pole & top?
