Welcome!
Have you considered active monitors? Universally used in professional recording/mixing studios. Consumer versions like the Buchardt A500 include room correction DSP, DAC's, and of course separate amps for each driver. But less well equipped and less expensive options like the JBL 305 Mk2 perform very well with deep bass and great dynamics.
Just throw in a server or server/DAC and you'd have a complete simple, compact, and inexpensive system.
