Right on! I do not like passive components in the signal path either. I got a high eff. driver for the efficiency, so there is no point in lowering the efficiency to get more bass. So the FE168EZ is in a proper back horn. The bass is still not acceptable, but the added efficiency in the mid band does compensate for the upper peaks (meaning that frequencies from 200 to 1KHz are on par with the 7.5KHz peak), so the overall feeling is that of a high eff. speaker with no deep bass. SO, I am saving money to add a proper pair of low Q subs to get things going under 60 or 80Hz. There is simply only two choices: flush efficiency to get more bass (in fact, there is no more bass, only LESS of the rest!) or keep the efficiency and ADD more bass with dedicated bass drivers.
