I second Chelillingworth.
If you want to go the kit route the basic Speaker he is talking about can be made w/ little fuss too.
The Jordon drivers can be had here for $115 each

http://www.ejjordan.co.uk/enclosures.htmlYou could have a good lumber yard(not Lowe's or sosmething)
cut the pieces to dimensions if you do not have access to a table saw. It is an easy speaker to make. I just made one for a relative. Total about $350.
I used the Ella tube amp(kit) from diycable to power it (doesn't need a pre amp if the source is a cd) and it is an
amazingly nice sounding system for the $$$. About $550

Really exceptional for blues, jazz etc. Both of the kits are easy. There is lots of support online for making the Ella. The manu. has its own forum.
The plans for the enclosure are not exactly how Caroline does it. I'm messing with the depth and tappering of the pipe a little. But the basic enclosure sounds very good!
Cheers,
