Someone just sold, or tried to sell, a beautiful pair of factory rebuilt Tympani IVa's for $2000 something. "Maggies with bass," as a friend described the Tympanis -- they'll smoke even the 3.6's, if you have the room for them. Maybe he still has them? Otherwise I agree, the 3.6's are a good choice, the true ribbon will do what you want with the highs.
