Suggestions to improve my box.

[Soundofav6]

I have had this box for 4 months now, it's treating me good. But I hear people say subwoofer is all about the box. So I figured I will measure the volume.



My first attempt in fibre glass and with no specific measurement. It measured 14.5 Litres. Recommended 16.5L But the range is (14.16-24.07L ) So I merely made it in the range.

If I kept eveything the same, except a slight 2-3L larger,would I get a noticible difference? How else should I improve it, the inside has been dynamated, would good old cotton pad be better ?

I have a urge to start another fibre glass project becasue I still have So go figure. It's still on sale if anyone needs some.

Stuff your box with Dacron. The sub will respond like it's in a larger box. You could also invert the sub, so that the magnet and driver stucture is not taking up space.

I have some dacron left, enough for a 200L box. BUt your in NSW, so try a local couch maker.

If you make it a bit bigger the sub will play a little lower at the expense of efficiency. As Science said, try inverting it and see if you like it.

For practice you should make a few new boxes... then sell them to people like me

dacron. Umm...would places like Bunnings have it ??

Inverting... Umm.. interesting.. don't think it will stand up straight. I may try it for fun, whats the deal with inverting the +/- terminals ? could some one elaborate on that ?


I have no problems making you one hawk, give me your measurements and a few days, I will just take the material cost and a donation box

Basically what I would like is something like the one you made that hides itself away in that little corner where the light normally is.


At the moment thats where my Fire Extingiusher is, but thats easy enough to move. The best part being that you get to keep your sub but still have a boot space.

Bunnings may have it. I'm not sure, i have a contact in a couch makers. As for inverting, when you flip the sub around, its going to be miss phased. So just swap the + - termanals around to rectify it. your amp or h/u may also have phase correction on them. My Monoblock does, you can swap the phase 180deg.

Thanks for your feed back guys.

Could you elaborate on that ? I don't quite understand the effeciency part.
