My bet would be on the big dipole Maggies...but then, I like planer dipole bass, better than conventional cone monopole bass.
However, as an Apogee speaker owner (I've owned 3 pair, and still own two)...my understanding from talking to other Apogee owners is that the Centaur Major is a "VERY" good sounding speaker system. I'm told that it has one of the best sounding mr/tw ribbons ever, from Apogee.
One member of the apogee speaker users forum mentioned not long ago, that he liked his Centaur Majors better than his Apogee Diva?....I was very surprised to read this! (he has owned Apogee: Fullrange, Diva, Scintilla, Stage, Centaur Minor, and Major...maybe even a few more?).
I owned the Centaur Minor at one time...same ribbon as the Centaur (and the Apogee Stage)...the Centaur Major uses a much longer and wider ribbon than these three. AFAIK...no other Apogee shared this (Centaur Major) ribbon design?
