Hi Alan,
Thanks for the reminder, I did not even stop of think of this. But of coarse it would be no different to hooking up a resistor in series to change the load, we had this discussion in another post when we were talking about problems with the HK receiver running M-80's. When I suggested he connect a resistor in line to alter the load to 8 ohms to see if the receiver still triped off, one of the things I told him was that it would effect the speaker sound but since this was not a concern not to worry about it. Hooking up the 2 VP150's in series would be no different, great observation Alan.
