You can build super scoop and load it with an 18inch 18 sound lw1400 @240 hz i have 2 and they crack the atmosphere between 20meters from the bins, got 2 crown xls 802 driving 1600 watts constant @ 8 ohms mono per driver.

how much power should I give the HD15? I think it is safe to say that I can manage to use a really big battery at least 50ah or something.. 

What about a 1850 bin? Has 105 efficiency and drops lower then the HD.. A little bit wider but not that much of a difference from a HD215..

Make a copy of a JBL 4530, loaded with a 15" JBL 2226H or modify it to accept an 18" JBL 2242H. That style of scoop is very efficient. Probably 6db over a bass reflex. This is a kick bin, meaning there's nothing under 40Hz and it is optimized for 50-120Hz. The kick is impactfull and will hit you in the chest.

You want a double 15" bass reflex. With a decent efficient driver it will be 104db 1w/1m

We just designed and built two with your exact dimensions! Not ready to release them on the world quite yet.

Why the wasted space below the horn mouth?
