This like pulling teeth...


Which exact driver are you using? Do you have all the specifications for it?

You'll need the Thiele-Small parameters if you want to design a subwoofer, and there are various web apps out there that can do the work for you, but without the data for the driver you'll be guessing wildly, and drivers differ a lot.

I have got 5.25 inches by measuring the drivers dia, there it has been printed as CSW 20W, 4 Ohms behind the driver and it has got dual magnets in it. These are the only specifications I have.

I think what youíll soon find out is that you cannot design (nor can anyone recommend) a box without the TS parameters. Iíve never measured my own but perhaps someone here will instruct you.

Or, just build a modest sealed box and see how it sounds. Make the box as big as you can tolerate. It will make more bass than sitting on a table, not as much as a properly tuned ported enclosure, but something.

For the vast majority of domestic speakers: multiply advertised diameter by about 1.1. Cube that. Build a box that size. Preferably different on all three dimensions. Half fill it with wool blanket, socks, or even fiberglass. This will almost always give a Q of 0.8 to 1.6, and pretty near optimum output.

So 5.25", times 1.1, is 5.775. Cubed, is 193 cubic inches.

7" times 6" times 4.5" is 189 cubic inches.

This is NOT a precision prescription. A 4 liter box is fine. 7 inches of 6-inch drain pipe is fine.

Thank you very much.
But I didn't understand what is 7 inches of 6 inch drain pipe? Is that a port dimension?
