Its gotta be. It goes against physics for a small box to be more efficient and have flat extended bass. Just cannot be. But might sound quite good still at low to moderate volume and soft clip increasingly as the volume goes up, limiting dynamics. Large scale dynamic works would suffer most. End results at higher volume might still be quite good, but can't be optimal in terms of dynamic headroom.
Smaller high efficiency speakers with low ends that roll off at higher frequencies, 50-60 hz or above say, like my "90db" Triangle Titus XL speakers for example would be less affected and probably a better match overall. Or larger more full range high efficiency designs.
