I'm looking at getting a new 2x12 cabinet, and want to put a combination of Celestions in it. What I have in mind is: - Heritage G12M Greenback, 8 ohm, 96 dB sensitivity. - Heritage G12H30, 8 ohm, 100 dB sensitivity Notwithstanding the tonal differences, and other speakers that I might consider, my question relates to the efficiency/sensitivity differences between the two types. From my university days, my thought would be that when run together, the power input would be spread pretty evenly across the speakers, and that the G12H would sound approximately twice as loud as the Greenback, and would therefore drown it out. Is my logic correct, and are there any users out there with this combo that can comment on the set-up?
