Yes, you can get that sort of response & sensitivity, provided that you're willing to accept a rather large box - I'd say at least 4-5 cb.ft. (~115-140 liters), maybe more. Remember, a loudspeakers bass extension is proportional to box volume, & in inverse proportion to efficiency. And deep bass is 'expensive'. Just to go 1/3 of an octave further down, say from 50 to 40 Hz, you need to either double the box volume OR accept half the efficiency (if you wanna keep the box volume the same).

This explains why loudspeakers that can deliver both bass & efficiency inevetably becomes large - & why typical small 'hifi'-type speakers are inefficient...
