A basic speaker can't do a lot to improve "room acoustics" [1], particularly below the Schroeder frequency where room modes greatly affect the bass response. From my experience, it's the bass that needs fixing in room, because even a "perfect speaker" will get boomy/muddy at some frequencies (ie. reflections overlapping constructively), and thin/null at others (ie. reflections overlapping destructively). And if you aren't going to worry about "fixing the room", then there are already companies/products like Kali Audio IN-5 speakers [2] that have squeezed in some good performance and tech (eg. active DSP with coaxial driver) in to an affordable package. There are ways to improve the bass situation, and one is by implementing "directional bass", aka a Cardioid array. This could be achieved with multiple individual speakers (add-on/upgrade existing system), or could be integrated in to 1 "speaker". Examples of the latter have been around for a few years - see Dutch & Dutch 8c or Kii Three. They are relatively expensive (which you could consider an early adopter tax), but affordable competition is starting to mature with speakers such as Mesanovic CDM65 [3]. There is another way to improve things too, and that is via "Active Room Treatment" [4] as Dirac calls it. Basically it uses excess capability in various speakers to "clean up" the audio of other speakers in the system by outputting "cancellation waves" (to cancel the problems). The results appear amazing, but they are taking their sweet time getting it released on to affordable equipment. There's also "spatial audio" like Dolby Atmos that should/could work around room problems in a similar way to Dirac ART. So good speakers (like already exist) + ART + Atmos + AI "upscaled" 2 channel source music could be the final frontier? But that's just for "mechanical" sound reproduction. Maybe in the future I can just transmit the song straight in to my brain, bypassing my ears and the need for speakers entirely?! [1] https://en.wikipedia.org/wiki/Room_acoustics
