they also have some 10" enclosures, but I don't really care about those, but if you do please look into it. My girlfriend agrees bigger is better, so I'm going after an 18". The eD a5-450 and CS18.1 seem perfect. The Epik Empire is a good sub if you got space to place it. I don't have too much space, but recently I rearranged my room and am now able to have it so that it has 6 feet between a opposing walls in a nook area, and 2 feet from the nook wall, but I still can't get it to blend in with my Mirage. Other than that it sounds great. Just disappointed I cant get it to blend in, and also I had to do a lot of moving around just to get it to sound good. I like the MFW cause you can just put it anywhere and it sounds great. The Empire requires careful placement consideration if you want it to sounds its best and understandably so given the dual opposing 15" woofer design that they copied from Seaton submersive.
