    Question home subwoofer w/ DB104 subs - box build

    hey there, i've lurked here for a while and finally decided to join after i came up empty handed on finding information on making a home subwoofer with my 2 DB104 10" subs.

    i was wondering if anyone here has any experience with making a box for a sub for in-home use. i want to use these for video games/movies/music.. so any help is greatly appreciated.

    my plan is to make this box:

    thanks in advance :)

    That box looks like a decent fit.

    The problem I see with that woofer is if you have enough power, sealed is gonna be the best bet. However, with a resonance pushing 40 Hz, you'll get much deeper bass from a ported box.

    Don't expect the tightest bass in the world. If you do, go sealed and use at least 300 WRMS for the pair.

    edit: I've got a few minutes so I'll run a few designs. brb

    Ok, so I've got some numbers.

    A sealed box should have 1 cubic foot of internal volume. If you give yourself 1 cubic foot as a total for the airspace and the speaker and stuff it fully but not packed, that would be tight. Large power amplifier required.

    A vented box will want at least 1.5 cubic feet of internal volume. Then you add on the speaker and port displacements. You're looking at a good size box. Maybe 20"h x 16"d x 12"w at the smallest. The port will need to be a slot port. 1" by 10 " needs to be 13 inches long. Remember that if you use a corner to terminate the port, its effective length will gain an inch(in this case).

    A bandpass box also has great potential. At a hair bigger than the ported box, it can be adapted as a coffee or even side table. Extension is pegged at -3 dB at 28 Hz and then again at 76 Hz. Front chamber is 0.6 ft3, rear is 1.5 ft3, tuned to 46 Hz.

    For a small room, go sealed. For medium sized rooms, stealth look and wife approval rating, go bandpass. Don't be a first timer cutting wood if you go this route. Lastly, a ported box with lots of power will yield the deepest, and meanest bass.
