The company did change hands several years ago, and I believe Gallo is no longer involved. I think there is still a dedicated Gallo forum on the AVS forums, and I'm aware of at least one small group who really modify the older models for better performance. Making the spheres is both difficult and expensive. I'm not aware of anyone making spherical cabinets for diy. You may want to look into Egg shaped cabinets as they have even better dispersion characteristics and less resonance issues compared to spherical cabinets.
