My gut instinct tells me that even any well designed speaker, high or low efficiency, is likely to have bass deficiencies unless setup properly and matched to the right amp and associated gear.
Also, I would not expect most amps to deliver equally excellent bass performance on both high and low efficiency speaker designs.
Other than these things, I would say the devil is all in the details....
