Dealer post disclaimer.....not trying to sell here but I have been selling completely active systems with time and phase alignment software which is integrated into the xover matrix for 12 individual drivers and separate amplifiers for each driver, for the last 10 years. Our latest incarnation is also completely wireless, have a peek.
