DO SI 18 full marty?

Ok, I have a full Marty, however, there is always more. What would a DO Si 18 look like with similar power vs 2 full Marty subs? I have space for another Marty, but DO sounds cool.
The Goal is to use an inuke 3000dsp to power 2 Si 18s d4s and get the most out of them. Space not a concern. The room is mine and the wife lets me play in my playground. Btw, full marty dual opposed..... what would the name be?

something roughly like this. dual opposed does little to nothing for frequency response. it is two sealed drivers.
this model was for 1 driver. 2 would give +6db across the board.
if you have the space and don't mind losing most of the frequencies below tuning, it is hard to beat ported.



Listen. It's All Good.

Blue is Dual opposed full marty. the green is dual ported martys. rule of thumb is each dual opposed cab would be ABOUT equal in output to ONE regular marty above tuning.

DO sounds cool, but doesn't do as much as 2 separate subs can for room nodes.

Only way I choose sealed is limited size (under 4cuft cab)
Or I had dedicated theater and used 6 to 8 sealed subs.

I think OP means two drivers in one full Marty (opposed). Not sure how that would work but sounds interesting.

What about building 2 cubes, then you can stack them OR move them in different locations.

I agree with Girmic, I think he meant putting two 18s in a single marty. They could be opposed I think. There should just be enough room to put them on the sides. But that won't be as efficient as two separate Marty's. It might be equal to two separate cubes though.

Two drivers in a Full Marty will perform more like a pair of Martycubes than a Full Marty.
