    Guys,
    I'm building a new sub for my HT, I'm going to build a cube.
    I've heard that for HT, Vented is better, but for music, sealed is..
    What do you guys think?
    Get back with me,
    Nathan

    100% true, its all a compromise to what you want. I recently read something where a very respected speaker designer mentioned something along the lines of take 10 piano manufacturers and listen to a model from each, they will all sound different but nobody will say they don't sound like piano's and who's to say which is better?
    This is how I feel about "good" subs designs, each has its strong points but each will generally perform it's duty and you will be 100% happy. If you listen to mostly music you may want go sealed but if home theater is largely in the mix ported will likely play louder in the lowest octaves.
    Either way I'm sure you will be 100% happy with whichever you decide on.

    Correct me if I'm wrong, it sound like you're not prepared to let go of the vented-box side of your decision just yet [​IMG] In that case, I'd suggest the SBB4 alignment. As you might already know, it has the best vented-box transient response (trading off a bit of bass extension, of course) [​IMG]
    What do you think?

    From what I understand, cubes really aren't the best shapes for speaker enclosures. Actually, they are about the worst are far as creating standing waves in the enclosure.

    Right, but if the cube's dims are small enough that the potential standing waves are higher than the sub's BW, it doesn't matter. For instance a 2ft i.d. cube has its first mode at c/2L, or 1130/2*2 = 282.5Hz, well outside the audible BW of an 80Hz/4th order XO.
