    what should you use to make a box

    i have 8 10's and am going to make my own box. what materials should i use and should it be ported or sealed. FYI they are the new Volfengag subs and i will have 350 watts RMS going to them. They handle 400. Does anybody have any info or any websites that i can go to?

    goto <a href="http://www.SoundDomain.com" target="_blank">www.SoundDomain.com</a> . Use either 3/4" wood or lots of fiberglass.

    Make it out of fiberglass or MDF if you want. I would go with sealed cause I like cleaner sound but ported is louder. Stay away from bandpass.

    Go with MDF or super-light MDF. Fiberglass is way to expensive and hard to do and if you're not a shop is almost definately not an option. For the type of box, with that many speakers I'd go sealed since you can have a smaller airspace box. You'd have to more than double it, most likely, if you wanted to go ported. Bandpass is crap unless you're using a bandpass with ports on the plexiglass side of the box. Not as loud as ported, not as clean as sealed, and not as deep as bandpass, kind of inbetween. But for a personal built box, a nice, sealed box woudl work very well. If you can do it, invert some of the subs, it'll look ******.

    If you invert some of the subs remember to wire them out of phase. <img src="smile.gif" border="0">

    Thanks for all the replies. I have decided to go with the MDF board in a sealed box. How do you wire then out of phase, and what does it do? I have never heard of that before, please give me some info this. <br /> Thanks

    The subs that are mounted normally ( basket in the box ) are wired like normal. The subs that are inverted should be wired out of phase. This can be accomplished by simply connecting the positive lead from the amp to the negative terminal of the sub. And the negative lead from the amp to the positive terminal of the sub.

    To understand this think of a subs two sides.<br />Both sides have the exact same output just 180 degrees out of phase from one another. By wiring the inverted subs out of phase in actuality you will be wiring them in phase with the other subs you have mounted the regular ( basket in the box ) way. Make sense ? If not, I can explain further. <img src="smile.gif" border="0">

    Re: what should you use to make a box

    wow is there some crap in here...

    mdf is cheapest and easiest to work with. sealed is easier to build than ported - less calculations and cuts to make.

    fiberglass can give you more shapes and curves but is more expensive and requires more labor. it is not hard, just time consuming.

    bandpass enclosures do not require plexiglass no matter where the port is.


    based on your knowledge and experience stick with your plan and go all mdf. be sure to use wood glue on all connections and seal up the seams inside with some form of caulk. spend some time at http://www.bcae1.com/ and you will find the answers to anything you may want to know.
