"Don't go with any ported speaker if you want to avoid fat midbase."
I know this can be a general tendency for ported speakers, but not always. There are many good ported designs (front, back, or bottom) each of which provides good advantage when applied properly.
If you like full, extended, bass t go along with detail and clarity in the upper ranges as well, in lieu of a ported design, your options may be only bigger more expensive speakers (that are also harder to place practically) location closer to walls and/or corners, which often negatively impacts imaging accuracy and soundstage, or use of tone controls or equalization (ouch).
