Power is inversely proportional to resistance, LCD-X is 21 ohms and LCD-3 is 115 ohms. LCD-3 resistance is higher because it reduces moving mass by using smaller wires with higher resistance. Therefore with equal efficiency, you will need about 5x more amplifier voltage to get the same volume level from the LCD-3.
I get that part, but is it something I should be terribly concerned about? If amp A does 500mW at 100ohm and amp B does 750 at the same, does that matter to me?
