Im having a hard time deciding between these 2 as I've o only heard the towers at different locations.The ML 40's seemed to be a little more detailed. And a little more forward.and the rx6 had very good imaging a good low end.Package #1 ml 40's Ml 3O center ml fx surrounds.package #2 monitor audio rx6 rx center rxfx surrounds.i can get the ML package for 2400.00 and monitor audio fir 1900.this will be mainly home theater use in a 13x24 carpet room 8' ceiling with a denon 3312.Are the martin logans worth the extra $ with the ribbon tweeter.I also have two subs which will be used
