There is a quirk of loudspeaker design that to achieve higher efficiency often leads to lower impedance, all things being equal. So although the 93dB efficiency speaker should louder for a given amplifier volume setting, it may actually be harder to drive due to the lower impedance.
The key points though are that these manufacturer figures are notoriously unreliable and will tell you nothing about how the speakers will sound, and in particular the 4 ohms figure will not tell you if there is a impedance 'dip' in the frequency curve that could upset a Devialet or many other speakers.
I think in summary that these figures do not actually tell you that much! Although @Mollengijs words are absolutely correct, in theory at least.
