Doubling the driver count parallel wired increases voltage sensitivity by 6dB, not efficiency. It doubles efficiency, which is 3dB of the sensitivity increase. It halves the impedance, giving the other 3dB voltage sensitivity increase. If you double the driver count series wired the double radiation efficiency still gives you an additional 3dB of sensitivity, but the doubled impedance takes that 3dB away, for a net unity gain. But you don't keep getting a doubling of efficiency with every doubling of drivers. 25% efficiency is about it with direct radiators, usually reached with between 16 and 32 drivers.
