An important question (at least I think so) - is your goal to have a pair of speakers that sound good for the least amount of money - or is your goal to build your own, so to speak, for the satisfaction, learning, etc that comes with it, at a modest cost.
As with many other things we discuss in this forum, it's often less expensive to buy what you want however you miss the learning, satisfaction, etc. Realize that we all value things (like our time) differently and have more or less resources (a good workshop, for example) at our disposal so the equation is different for everyone.
