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!

Thanks for so many great recommendations. Had no idea there were this many options. Dynaudio and Elac are most appealing right now. Gold phantoms just too expensive. 
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.
