I think I have everything pretty much planned out currently. I have changed my mind and just went with an 18" driver from Exodus audio, Maelstrom X, that combined with a EP2500 gets a ton of good user reviews over at AVS, so I may as well give it a try as well. Now I need to find a 24 inch sonotube supplier. Finished the whole thing will come right at 6 ft and will be tuned to 17.3 Hz, in room gain should give me a few extra HZ on the bottom end.
