Dual subs is cool....
I like sealed subs as I think they sound tighter
What do think of that 12" Sunfire Sub with 2,700watts?
I don't think much of Sunfire products at all since Bob Carver's departure and my only experience was a friend who had one of the original Sunfire subs but later had amp problems, it did sound nice but I hadn't much experience with subs back then.
There are excellent ported subs as well as sealed, design and execution go further than a general type. The top of the heap of the ID sealed subs IMHO is the Seaton Submersive HP and multiples would be an awesome way to go.
Your space isn't particularly large at 2240 cuft, assuming an 8 ft height, but depends on how large that door opening is and the size of the kitchen as well. Ported designs can often provide higher output and lower extension in larger open spaces than a sealed sub can. An excellent ported design with good output and extension is the Rythmik FV15HP.
I should also mention JTR Speakers subs, the Captivator is very well thought of around here. Also Funk Audio http://funkaudio.ca/
for consideration, some beautiful cabinet options on top of great performance...but will be a bit pricier. There's some great AIY & DIY options too if you want....
You might want to look at some of the testing and information here http://www.data-bass.com/home;
Josh Ricci is the main 3rd party tester out there for subs (and a member of these forums and audioholics.com also).
