One practical solution is two-ways plus unobtrusively sized sub-woofers, like the Linkwitz Pluto+ system I run in my bedroom including its pair of 14x14x10.75" high sub-woofers. When such woofers are equalized for low frequency extension you need to watch for thermal compression at low frequencies but this is not a big issue on music (versus home theater) due to the limited power in the last octave. The other is a 3-way speaker system you don't have to move, perhaps with wave guides to limit front-wall reflections.
I've never heard a 2-way which produced both good midrange and bass.
The issue is that with conventional dome and ribbon tweeters you need the midrange driver(s) to be acoustically small approaching the tweeter cross-over point to maintain monotonically increasing directivity, small drivers need to move farther to provide a given displacement, displacement requirements for a given volume quadruple with each lower octave, and both IM and harmonic distortion increase with displacement.
One compromise is reasonable sized mid-range drivers that do fine at low volumes and without bass on things like jazz vocalists but distort both bass and midrange once low frequencies are present at moderate volumes. Ports and transmission lines provide additional low end extension at given excursion limits but aren't enough, and leakage from ports can degrade midrange performance.
The other is large mid-bass drivers that have the displacement for bass but are acoustically large which produces an unnatural sounding power response dip in the midrange. This is especially bad where the speaker designer fails to use an extra beefy tweeter (1" + dome with long throw like .5mm xmax) which can accommodate a low (1.5KHz) cross-over point.
The Earl Geddes (gedlee) / Duke LeJune (audiokinesis) approach to speaker design mates a wave guide which limits high frequency dispersion to a large midrange with similar polar response (perhaps matching -6dB angles). That might get you midrange and bass but those speakers aren't built to have bass below 80Hz; presumably due to efficiency (Hoffman's iron law dictates that enclosures must grow 8X to maintain the same efficiency one octave lower) and quality (distributed bass from separate enclosures produces more uniform frequency response, especially over a seating area).
