...measured into an 8-Ohm load resistor and then into the speaker, while the latter is measured with ONE WATT into the rated impedance of the speaker.Of the 6dB increase in sensitivity, 3dB comes from drawing double the power out of the amp due to halved impedance, and 3dB comes from doubling the cone area. THAT's the 'theoretical amount' I mentioned in my note.

- Didn't read my note, huh? :-) It changes SENSITIVITY, not EFFICIENCY. The former is measured with 2.83VAC... - jeffreybehr 11:28:54 03/20/07 (2)

- Yes and no. EFFICIENCY is increased 3dB and SENSITIVITY is increased a further 3dB. - jeffreybehr 18:51:27 03/20/07 (0)
