I have two big old 1980's Sanyo 3-way tower speakers. They have 10" woofers, a 3-4" midranges, and some weird tweeter that you can't see because it's behind some sort of heat spreader that points down (weird). They also have some sort of adjustable tone dial. I'm wondering if I can purchase JUST Paradigm Studio drivers fairly cheaply to match the rest of my Paradigm system with. I know the shape and size of the box will change the sound a bit, but I figured...it's just sitting there, I have to do something with it. And why not start a DIY .5 project. If I can't get Paradigm drivers for cheap, does anyone have suggestions about where I can get good drivers for it online so that I can build it myself? I plan on packing some insulation in there if there isn't any already. Thanks guys (and girls).
