Lets start the topic off by saying that I *Already Own* a pair of these rockville PA 18's.

Now I'm not here to argue about how much better higher wattage ones could be, since I already own these, it seems counter productive to tell me to throw these out when I could have fun making a case for it. For $60/ea $120/pair these are keeping up with the orginal drivers in my yorkville SW1000 subwoofers, that would've cost me $450/ea $900/total to replace from long n mcquade.
What I'd like to do is put them to use and use a case that could give them a bit more bump (since they prob need it being cheap drivers) and since I already own two of them and got a bunch of mdf I can easily build and test a prototype cab without spending any money.
I've thought about making a gsub/dual reflex with them or a value buster subwoofer system (vbss for short that uses a cheap $90 18 inch dayton driver) or a 4th order cab (like car audio 4th order walls) or a cubo 18, but I wonder how effective these cases are for these drivers since most of these cases (aside of the vbss) have been designed with higher wattage drivers with more xmax in mind.
When I put them into winISD, when it asks you what type of box your building it says the driver has a EBP of 54.2 making it better for a closed or 4th order box if I'm looking at this correctly. (The graphic is going up to just under half way) So this got me looking into into 4th order designs but that seems to be more of a car audio thing while I'm looking to use these as outdoor PA at ranges of 1 to 30 or 40 feet, it makes me wonder how effective a 4th order or vbss would be at that range verse something like a cubo or dual reflex that are obviously meant for longer ranges.
