It would also be necessary to know the T/S parameters of your woofers to aid in box size to optimize the frequency response. Do some search's on DIY Subs and visit some of the online suppliers of speaker components. Here's some links to get you started...

The first is a general on speaker design types and what they are used for.
The next 2 are common suppliers of parts and T/S parameters.
The last is a useful software tool for "seeing" the freq.response curves for a givin speaker in a given box type and size. It's free and "fairly" accurate.
You might also cruise over to the DIY and HT forums and read a little history as many have posted some pretty good advice on the subject.

If you want a starting size for enclosures and you can't find the all the T/S parameters on your drivers, a "general" rule I follow is take the Vas of the driver in cuft and halve that for the enclosure size of each driver. Just a starting point! do yourself a favor and do the research before you begin and you'll thank yourself for it!
