    Box For SX 15

    Alright, these are the specs i came up with for my 15" SX running at 600 rms @ 4 ohms and i just want to make sure that they are alright, or if there is something I should change about it.

    They are as follows:

    -Internal Volume-4.0ft^3
    -Port Size-2.5 wide by 16.5 tall
    -Port Length-21.75
    -Tuning Frequency-32hz

    And also, do i need a subsonic filter?

    Depends on your taste. Throw on a subsonic with that tuning and I'd assume you'd lose a little bit of "feel" but at the same time draw out a little more "sound"

    Try it both ways, you certainly don't need it

    Finished the box, as soon as i can borrow a digital camera i'll post some pics on here.

    I do have a question though, in a few places the holes i drilled must have been at somewhat of an angle and the screw cracked the wood on the outside a bit, is this going to be a major problem? Or should i just make sure it's covered with alot of glue and reinforced by another screw?

    And also, due to a crappy old circular saw (blade wobbles a bit, it is a new blade though) a couple of the cuts were a bit off on the port boards and there is a 1/16" gap or so between the port boards and the top board, if i squeeze alot of silicone caulking in there and make sure there arent leaks will it be fine? Or with that large of a gap is it too big even for the silicone caulking?

    i woulda went for a larger port, but if you rounded all corners it should be fine.

    as long as you used wood glue i wouldnt worry about the splitting wood. fill the gap with silicone the best you can and it will probably be fine as well. 1/16" isnt much. just seal it well.

    with only 600w id imagine youd be fine without a SSF.

    What do u mean by larger port? wider? or just more port volume? Either way i went with the port length that winisd said to go with for 2.5 x 16.5.
