Where have you looked? Dynaudio, Morel (well 9" anyway), DLS, come to mind. Or you could go DIY for the eight and crossover active via amp to a 2-way component set for more options. Or full DIY set. I think Memphis had a 8" 2-way.
This is ironic as I had a set of active 8" 3-way Morel set for sale forever on here and on CL and could get no interest except in the mids, and nothing serious. I finally had to sell them on ebay. Went for less than $200. The guy who bought them about came on himself when he unwrapped them and I don't blame him.
