Yup. The internal cabinet bracing isn’t well designed and built. Those big boxy cabinets of the Motion 60XT also allows internal standing wave inside the speaker cabinet that creates cabinet resonances or coloration. That was pretty much what I was hearing when listening to these Motion 60XT at the hifi store. It would have been fine if it was well braced internally but unfortunately these speakers aren’t.
If you want to go with Martin Logan you should look into their electrostatic planar / hybrid speakers. They are pretty awesome. They throw big soundstage and sounding very vivid especially with vocals due to a non-cabinet design.
They aren’t for everyone though. Either you really love them or you don’t. They aren’t my cup of tea however. It’s all about personal preferences. But these ML electrostats planar speakers require good quality high power or high current amplification from your amplifier in order to do these speakers justice. These electrostats planars need high current amplifier in order to properly disperse the sound throughout their planars. The bigger the planars are the more power hungry they get.
I wouldn’t recommend running these off an AV receiver or incompetent amplifier.
