In Reply to: Didn't read my note, huh? :-) It changes SENSITIVITY, not EFFICIENCY. The former is measured with 2.83VAC... posted by jeffreybehr on March 20, 2007 at 11:28:54:
Efficiency is acoustic power out versus electrical power in, expressed as a percentage. Mutual coupling of two identical drivers (what you refer to as doubling the cone area) doubles the radiating efficiency of the system, which results in a 3dB increase in the voltage sensitivity. The phenomenon is frequency limited, and total efficiency with direct radiators cannot exceed approximately 25% (D.B.Keele, 91st AES convention, AES preprint #3193).

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