I certainly would not. 38 hz to 20kHz? my back side. Bass is very disruptive to higher frequencies. It will cause distortion particularly at higher levels because of the long excursions it takes to produce bass.
In order to limit excursion you have to use a very big driver or many small ones like Bose 901. Even speakers that can easily run full range like big ESLs should have the low bass taken away from them. Next, a driver that size is going to beam high frequencies like crazy. I am all for controlled dispersion but in order to hear anything over about 12 kHz you are going to have to be dead on to each speaker.
If you really want a single driver speaker you get ESLs and put subwoofers under them. Trying to do it with dynamic drivers is highly problematic more so than using multiple drivers and crossovers.
