[QUOTE="Vaughan, post: 60319, member: 693"] It's certainly not hair splitting when we are talking about two different things. You have two different terms and they should be treated as such. You can't just lump both together. Both equations are not one and the same. The math isn't the same. Efficiency is power out/power in. Sensitivity is power out/voltage in. Power and voltage are certainly not the same thing. Clearly, impedance is a factor here. And no, you can't say that the higher the sensitivity, the higher the efficiency because that's just a blanket claim. If you have two speakers with equal sensitivities of 90dB/2.83V and one has a 4 ohm impedance and the other has an 8 ohm impedance, the latter speaker will have a higher efficiency, since the 2.83V will represent half the number of watts. That isn't 'hair splitting' to me. Speaker impedance is not constant with frequency. If that were the case then your claim might have merit. [/QUOTE]
