Ok so I need to work out how many litres my box is, I have done some measurments but thats as far as my simple maths can take me lol

there you go Champ

these are very close to correct

now my math isn't 110% but i think it's close enough, that any variation in my numbers, wouldn't not effect your port tuning much, if anything at all... if you decided to go bandpass, it would always be worth going back over all your measurements, as added wood inside the enclosure will alter the size etc...

but to give you quite a close indication, i ended up working it out to be around 25.3cf, or 716.4 liters... now as i said, that isn't perfect, but it should be within 15-20liters... which in an enclosure this size, isn't going to make much difference to tuning...

you sir are a sexy man

When I bought it I think the boys guesstimated it was about 23cf so they were not far out.
