impedance vs sensitivity

Hi folks, I wonder if it is possible that a speaker is highly sensitive (>92dB) while having a very difficult impedance behaviour (1-4 ohms)? Could you also give some explanation regardless whether this is possible or not? Thank you in advance.

Yes it is possible. Desirable maybe not at least at 1ohm but possible. Would you like me to build you a loudspeaker with such specs? I have a loudspeaker in my office 92.5db 1 watt 4ohms. Sure many others available near this spec.

I know the VSA VR-6s that I owned were 96 db with impedance dipping down to 2-3 ohms (on the woofers).

Which means that an extremely low impedance speaker (1-2 ohm) could be sensitive? A 50 Watts amplifier is therefore enough?

50W SS or tube? SS might work,tubes would be pushed too hard to develop power into that load.
My Air Tight ATM 3s drove the top-end of the VSAs,but were not enough to sufficeintly drive/control the woofers (same with Audio Physics Virgos).You could switch them into "ultra-linear",but the magic was gone.
