Fairly certain EVM-15B Series-II drivers were found in some Hartzell era Sunn 2x15s. A pair were definitely in my 215B and they're reported to be in a 215BH or two I believe . However, these cabs are of a different era than your 115S(V) but I was very happy with the sonic results of the speakers. They're also in a V-4B Ampeg 2x15 a friend has and although that cab is massive it's got that EV sound with an old folded horn Acoustic vibe to it. Ed, I think the word I was looking for was differing and not conflicting.
