I am looking at the Motion 60XTi and the 40i. I like both, but prefer the 60.I agree, I don't think there is a "lack of enthusiasm for ML". The only complaint I see is how they increased price 2x in around a year or so. We still have a good number of members on here buying new speakers at the new high prices. To me that show enthusiasm for the brand.
The 60s sound fine just as is, without a subwoofer, but the 40i's sounded amazing with a subwoofer, in fact it seemed like the speakers themselves disappeared into the room. Pretty cool.
But my problem is my room height. I have drop ceilings, about 6.5 ft high.
The 4 ft tall 60XTi may work okay in the room, but it is the dispersion of the tweeters on both models that is questionable. The 60XTi tweeter dispersion is 30 degrees and the 40i's dispersion is a huge 80 degrees. I am trying to determine if I will have some ceiling bounce issues with either speaker. From my calculations the 40i's may be the worst match for the room because at least the taller towers' dispersion is much less, albeit the height of the speaker itself is about 6" taller than the 40's.
