Hello Wayne, may I ask what are the drawbacks to this design compared to the other 7Pi corner speakers? I like the idea of the midrange frequencies coming straight at you, but since I have heard neither I thought I would ask. I guess the extra crossover point would be considered by many to be a drawback.I am still trying to choose between the Theater 4's and the 7 corner. I may have an interest in the 3-way corner.
