you are on the right path. Bose does that with their 901 home speakers. having 9 4.5 drivers combined to give the equivilant of a much larger driver combined with the equilization. keep this in mind when people change out their systems with "common" drivers and amps and have NO professional equilization done. Dr Amar Bose has not been researching this for the last say 40 years just for the hell of it....
