A couple of these sealed in a 2 cube net box will give excellent results:

Unhappily they are not cheap. Neither is the 2k amp needed!

yah joe they saying 1.3-1.5 per sub
i only have 0.8 each if sealed and 0.2 displacement of sub

was thinking
1x fi q 15" sealed in 1.7cuft (min rec is 2)
or 3 fi q 10 ported in 1.5cuft (0.5 each, just on min req)
common chamber with sheared port 15"x0.75"x 19"long

Those have a lot of output but maybe not true SQ sub, they sound nice and loud though.
