In my continuing flirting with other speakers apart from my beloved 2.4s, I heard the Magnepan 20.7's yesterday run with Vandersteen crossovers (the ones that come with the 7s) and two Vandersteen subs. Impressive but on most music I preferred the sound of the Magnepans by themselves without the subs. Time and phase coherent first order crossovers all the way around.
