Well, I'm about to start my basement's final subwoofer design and I might need a little bit of advice along the way with this one.

I've decided to go a slightly different way than two 12' or 15's.

I just ordered 12 of NHT's 10" subwoofers (new) that used to be used in their "SubTwo" boxes. My understanding is that they perform pretty good, so I figure why not overkill the whole thing and just use 10-12 to be on the safe side. Xmax is stated at 12.5mm. I'm not really sure how these will compare with two 15's, but I guess it's too late anyway. One helpful member here said I should go with 12 to get the Ohms to work out right.....so I did.

Anyway, here are the specs: I have to be honest, I'm in the learning stage here, so I don't understand most of these numbers just yet.

Re: 9.58

Fs:21.5

Qms: 2.952

Qes: .444

Qts: .386

Vas: 103.84

Cms: .00561

Mms: 97.8

BL: 16.87

SPL: 85.47

Zmax: 73.2

Sd: .03631

Xmax: 12.5

Hg: 8

Hvc: 33

Their product sheet says:

Frequency Response:21Hz - 180Hz, +/-3dB

If anyone has any recommendations on box shape, or cubit ft per sub, it would be much appreciated. I have read that they should be in a sealed box, but I'm not sure of the size just yet. Power will be from an EP1500 or EP2500.
