how do I work out this

[busterno1]

could someone tell me how do I work out how much room do I allow for the port in a box.

Do I have to include the air in the port ?

because I was thinking of sealing up the ends & sticking it in a bucket of water .
Then measure what have left afterwould .
Is it allright to just fill it with water then measure that .
Thanks

The volume of the port (including the air inside it) will take up space inside the enclosure that needs to be compensated by making the box bigger. Same applies to the drivers and crossover.

You can calculate the volume of a cylinder by....

Volume = (3.14 x radius^2) x length

If the radius and length are in centimetres then the answer will be in litres.

Nice one

No, this way the answer will be in millilitres ! You vave to take decimetres for the calculation in order to get litres.

You're absolutely right, Charles. I don't know why I thought that the answer would be in litres!

Thanks,

Just divide your answer by 1000 and it will be in litres.

1000cc=1 litre, all revheads know that.
