RE: why so rare?

Very simple. Hoffmans Iron law. In order to have efficiency high in a small bookshelf speaker the bass is sacrificed. It is easy to build bookshelf speakers with an efficiency above 90dB if you are willing to be down 10dB at 50Hz. The compromise is to build a 95dB bookshelf speaker system that rolls off steep below 120Hz and use a pair of powered subs.
