Looks like a pretty sweet find to me. As long as you can get the x-over figured out properly you should have a nice set of towers. Why did the guy sell them in the first place? Crack addiction he needed to support? LOL, sorry i just cant see starting a project especially like that and not seeing it through. And then to let it go for half of what you have into it! INASNITY! Keep us posted. Im with youat the moment lost in the world of DIY speakers biting off more than i can chew. Hopefully the end result will have been worth the time for you.
