duc-k-t tape or silicone or whatever is only the small problem. the larger one in rewinding a voice coil how'bout that?
i'd inspect visually the voice coil first before trying any of above said methods to cure the diffusor.
c'mon Slap,
there are plenty of opportunities to get a kit for less than $200 to build up a superb sounding monitor that literally smokes all entry level Kefs Tannoys and B@W's. It's very easy to start with kits but after that you can build up a speaker only on crossover circuit and cabinette drawings from row materials that even more can save you money.
