In Reply to: Re: Didn't read my note, huh? :-) It changes SENSITIVITY, not EFFICIENCY. The former is measured with 2.83VAC... posted by Bill Fitzmaurice on March 20, 2007 at 13:03:56:
Yes, output increases (6dB) when you parallel the 2nd driver, but now you've driving it with TWO Watts. When one decreases the Voltage to reduce power to 1 Watt, output decreases 3dB but the output is still 3dB higher than it was before we started.So when we parallel an identical driver, efficiency increases 3dB and sensitivity increases a further 3dB.

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