BTL 18" box, does this suffice?

I currently have a single BTL 18" wired at 2 ohms on a Soundstream DTR2200.1 in 7.5 cubes. At first I was running the sub off of a zx1000.1d, so I made the box large to make up for my lack of power, now that I have a new amp even though its not much more RMS than the zx, its making the sub bottom out so I figured its time for a recone due to slight coil rub from bottoming out and needing a dual 2 to get the full power out of my amplifier. My question being would 16" high, 41" wide, 25" deep, inch and half mdf for the entire enclose and two 6" aeroports 17" long at 34.5 hertz with two inch and half steel dowl rods for bracing (my father was a welder and I get steel and work at cost) suffice for a single BTL 18" on 2.2k RMS?
