I have a customer who's using Wolcotts on a pair of Dunlavy's (Model IV's, as I recall), and he's quite happy with them. I have another customer who tried Wolcotts on Wilson Maxx's and as I recall he preferred the Tenors. So unfortunately I can't give a sweeping recommendation that the Wolcotts will excel with all cone speakers. Most of my Wolcott customers are using them with electrostats.
What speakers do you have in mind?
