I'm using about a 4.6cu ft enclosure. But the Dayton has been said to work best in a 4.0 cu ft.
With the single Dayton I'm able to rattle my walls with 16Hz test tones. The pictures in my bathroom shake if I play bass heavy dubstep at near max volumes. Needless to say, in my 2500 cu ft space the single Dayton is borderline ridiculous. I say borderline, because it's ridiculous for the average person while being "meh" relative to some of the systems here on AVS. lol
Two Daytons should do exceptionally well in a 3500 cu ft space. For sure you would have strong output down to 20Hz, most likely lower, and EQ would allow for you to smooth things out nicely. I have great output down to around 18Hz (still audible for me) and I can notice 16Hz is where things start to tapper off.
If i'm not mistaken, the only benefit from having a dual opposed design is the cancelling of vibrations. While this may be necessary for some subwoofers, you shouldn't have any excess vibrations or "movement" out of a 100+ lb, 4.0 cu ft sealed 18. Ha. Two 24" cubes would be more appealling than a much larger dual opposed enclosure. The benefit of having two seperate subwoofers would far outweigh the benefit of running a DO setup, IMO.
