thanks for replying again.You’re welcome.
RoomPerfect is a feature of the TDAI-3400 is Lyngdorf Audio’s proprietary digital room correction technology which maps and corrects for the acoustical errors of your room.
Regardless of the theoretical advantage active speakers have over passive however both types will ultimately be placed in a room. RoomPerfect will correct the acoustical errors of your room and helps your loudspeakers perform at their optimum and that's what really matters.
what we need then is roomperfect "installed" on a pair of active atc's - game over !
