Gonna build two more subs.... But which design

I currently have two ixl 18's in 28"deep "Marty cubes ". I have them behind my couch right now but will move them up front to act as stands for my newly acquired triple 8's. So what I want to do is build two more enclosures for behind my couch with a 24 " depth so the drivers will be facing into the back of the couch (nothing like two 18's kicking you in the kidneys when you're watching movies). Do you guys think cubes will do or should I go for some side firing mini Marty's? The room is an L shape , I sit about 16 feet back from the front wall with about six feet behind me. I plan to use another pair of ixl 18's as well.
Any ideas from the peanut gallery?
Thanks,
Ivor

The only reason to not go to a full size 2x2x4 sub would be because of looks/too big. If you can fit it, do it. Otherwise a 2x2x2 cube is also fine. You just get a bit more output from a 2x2x4.

Does it make any difference as to how far away you are from the subs as to how low you'll hear? I got a friend at work here that says I don't have enough distance to be able to have 15 or 16 Hz with authority. ... I think he's full of himself but, opinions?

So I just got this idea in my head. .., feel free to say it's a stupid idea but here it goes.
Take the Marty cube design and stretch it out to like 24x24x32 and add a fourth port, what would this do to tuning and air space etc. ?I need the ports to be coming out the same "wall" as the driver so that it doesn't run into my room wall. And the top isn't ideal either due to two young children in the house.

You can change the size however you want. You might have to change length/diameter of the ports though. Or just do a slot port.

The martycube has more punch then bigger models in the 50 to 80hz range. If that's the frequency your looking for a cube is better. If you want 18 to 40hz then minimarty or bigger.

What do you think about two cubes up front and two mini' s near field? Or just do two more cubes because I can't hear under about 18Hz anyway. ...

Two minis nearfield . The combo of two mini and two cube should meet your bass needs for quite awhile(I never say forever for bass )

Putting subs within 3ft is typically 12db louder.

Only crazy people go beyond quad 18's

So after going home last night and building a mockup of two minimartys behind my couch...... I made the decision to just do two more cubes. You really don't realize how big these things are until you see a completed unit or facsimile in your room.

Yep, I made my mock cube out of cardboard to see first. 2 ft cubed does not sound big until it's in the room. I start my build this weekend.
