In this case, my only option is replacing my current drivers with the alnicos, as the latter are also suitable for the superhemp cabinets. I can still use my 8W 300b amp with this driver (93db sensitivity) for most occasions (chamber music, Jazz, soundtracks), I guess. I wish I knew about their availability or any other options. As I mentioned before my primal goal is getting closer to the feeling of a concert hall, for a little more extended low end and better layering for large scale orchestral music . I feel somehow puzzled. I am also worried about the process of replacing the drivers (without relatively accurate instructions) in the cabinets, because I want to avoid any clumsy drilling. Besides, I didn't mention that one of the the whizzers is a little damaged. Isn't this servicable (by replacing the drivers I mean)? I ll' try not to contact Louis, unless I get a little more info.
