Ok, so I'm configuring my new Marantz receiver and I'm trying to find a good crossover point. Anyone with the Monitor 50's or the bass box that comes with the RM6750 that have some suggest crossovers for the speakers?
With the H/K AVR154, I believe I running at 100mhz - but the Marantz is a different animal altogether (I'm finding out).

Front L-R are monitor 50's, center is CS1, rear surrounds are RM6750 (as is bass). Thanks for any opinions!
