    Ok guys, you're the experts, i'm not. Here's what i have:

    From car audio: Kicker Solobaric S12d 4ohm SVC. (this is the older round model)

    Fs 18.13hz
    Qes 0.33
    Qms 7.10
    Qts 0.32
    Vas 206L
    Sd 530cm^2
    Re 3.51
    Xmax 10.3mm
    Xsus 14.2mm
    [email protected] watt: 87.5dB

    those are actual DUMAX specs.

    I have a 250w @ 4ohm Plate amp from MCM. Box size would be be preferably smaller than larger.

    It will be in a living room with hardwood floors, and plenty of windows. Plush couch and chairs will be the only absorbant mass in the room.

    For listening preference- whatever is well rounded- it will play for movies, but mainly for music- and probably more on the softer end- no metal or rap.

    It will be teamed with a pair of mid-grade B&W's

    What do you guys think for an enclosure.

    Thanks for any help!

    2.5-3cf sealed (with 2lbs loose stuffing) looks pretty darn good for that sub. Should be pretty close to what you are looking for. If possible, I would try to get the enclosure as close to 3cf or larger as possible. This should get you very nice extension and a pretty low final q (good for your "soft" music). I wouldn't go much smaller than 2.5cf with heavy stuffing.
