Impedance or sensitivity?


In assessing if a speaker is easy to drive, do you consider more the impedance (in ohms) or sensitivity (in db)?
Like between a Harbeth with 6ohm, 86db vs a VA Mozart with 4ohm, 90db, which is easier to drive?

In my opinion the impedance curve is more important. We had an opportunity to exhibit at THE SHOW in Las Vegas with FritzSpeakers. The Carbon 7's are 87dB sensitive. One would think this would not be a good match for a 300B zero feedback SET amp rated at 10 watts. However, the Carbon 7's are 6 ohm minimum and a very smooth impedance curve that matched up with the 6 ohm output transformers very nicely. We were getting very loud levels with no distortion from the amp. Several people were amazed at the fact that the combo could actually work let alone sound as good as it did.
