Use this device to find out the parameters.

There are other ways to measure speaker parameters with a SPL meter and sine wave generator, but in the long run this is the easiest and most cost effective way of doing it.
Use this to determine what size box to put it in.

If you want a cheaper route you can also find some free software to find out what box to put it in (just google or yahoo search "free speaker box design software").
