Best options for active speakers $4k or below?


Want a simple but superb sounding all-inclusive active speaker for my elderly but loud-music-loving mother in NJ. Used is OK!

Thanks!

Review Droped onto youTube today ... no first hand experience with the brand but ... from a design standpoint not much would appear to be overlooked ... using a Wave Guide to integrate the High and Mid / Low drivers would be a big plus with many integration innovations handled with DSP.
