"In your opinion, what is the best way to make a loudspeaker that is "room friendly"?
1) Fairly narrow, uniform pattern over as much of the spectrum as is feasible. This becomes difficult to do at long wavelengths, but Jorma Salmi did it in the Gradient Revolution. Aim the pattern to minimize early sidewall reflections.
2) The reverberant energy should have very similar spectral balance to the first-arrival sound. This can be accomplished in a number of different ways.
3) Include some way to adjust the bass to compensate for differences in boundary reinforcement from one room to another.
4) Try to physically spread out the locations of your bass sources (woofers & ports) with respect to room boundaries, so that they interact with your room's bass modes differently. This can help smoothe the in-room bass.
5) Since some rooms are bright and some rooms are dull sounding, have a way to adjust the treble, especially the high treble.
6) Make the speaker so attractive (or invisible) that your wife will gladly let you position it wherever you want in her liviing room for best possible sound. Yeah right.
"And, if we want to create a truly versatile loudspeaker, is it necessary to settle for a design that is (as the saying goes...), "Jack of all trades, master of none"?"
Those on my side of the cash register try to come up with products that will meet the requirements of those on your side at a price you're willing to pay, and some specialization is indeed called for, which inevitably involves tradeoffs. In fact, I would even consider "versatilty" a specialization, as its achievement trades off performance in one or more other areas (like exchanging bass extension for efficiency in order to achieve more versatile amplifier compatibility).
Take for instance the very first thing I listed above as a contributor to room friendliness: A fairly narrow, uniform radiation pattern. If room conditions permit, in my opinion better performance can be had from a good wide-pattern loudspeaker. The former might be called the "jack of all rooms", and the latter the "master of some".

Me being a dealer makes you leery?? It gets worse... I'm a manufacturer too.
