WinISD. HELP!!!!!!!!!!!!!!!!!

[Dannyball]

Does WinISD when it gives you the measurements of the box does it include the amount of volume the driver and the vent is displacing?????

Also when i build the sub i am going to pad the insides of the sub with roofing felt do i have to count the thikness of that aswell to get the final measurements???????????

How accourate do the measurements of the box need to be?????

[baggystevo82]

as far as the need for accuracy goes, just type in some 'innacurate' box volumes in winisd and see how much it effects the response.

Box measurements can vary up to 10% either way without much difference in in-room response, so don't fret too much. Stuffing increases the apparent box volume, so you also don't really need to worry about that either. If you use loads of felt damping, i.e. more than 10% in volumes worth, you will need to allow for it.

However, AFAIK with Win ISD you do need to allow extra for the port and driver volumes.

Other than the felt on the inside of the box is there anything else i should be stuffing in there i.e. insulation and will that effect the volume?

Speakers?


Sorry, couldn't help myself.

As pinkmouse said, make sure you remember to allow for port volume!

[pinkmouse]

If you have a ported box, a little insulation round the walls is a good thing, if enclosed you can put a lot more in. However stuffing is usually done to taste as the last stage of construction.

If your crossover is big, then you might want to allow a little more volume for that, otherwise just go for it

I've got some roofing felt about 6mm thick. Will just lining the inside walls with that do?

Thanks for the help so far.
Should be starting to build the box tomorrow
