    Re doing my box

    Well I have a box that is 10 cubic feet net tuned to 38.5 hz for my RE HC 15's. I was thinking about extending the ports to make it tuned to 30 hz. It is actually 2 chambers, 5 cubes each.

    The port right now, is 62 sq inches (per sub), and it extends 16 inches into the box. The internal depth of the box is 22.75 inches. I checked on WinISD and it shows that I'd need a length of 37.5" to tune it to 30 hz, keeping in mind that the internal volume would be about 4.2 cubes per sub or 8.4 for the pair.

    I was wondering how I shoudl go about this. I really don't want to take my entire wall out. Do you think it would be possible to take the back portion off somehow without breaking stuff up? I don't want to design an entirely new box, I just want an easy way to use the box I have, otherwise I'll just leave it as is.

    Thanks,
    Craig G

    Re: Re doing my box

    you would have to take the back wall off in order to fit the extension for the port. however, if you built the box with strong glue, it may be a bit hard to almost impossible. post some pics of your box so we can have an idea of how it's constructed.

    I would think it would be a lot more trouble than it is worth. The problem with the box's I build YOU CANNOT GET THEM APART without destroying the wood.

    Re: Re doing my box

    That is what I was thinking. I have some pics in my gallery of the box. I was thinking taking the back off would be the way to fix my problem but I did screw and glue it in place.

    Also, I was thinking maybe I could construct something through the woofer hole if I took them out, but that would be much more difficult.
