I currently sell the Martin Logan Motion line and used to sell the Paradigm line at my old place of business. Two different animals. It comes down to the high's for me, the folded motion tweeter of the Motion 40 sounds much smoother than the satin aluminum tweeter of the Monitor 11. Both will produce good bass with the right electronics. Be warned, the only down fall to the Motion 40's is that they are 4 ohm and if you are running them full range on a receiver, you will have a hard time if you like to listen loud. Most receivers will not enjoy and go in to protect.
I couldn't be happier with my Motion 40s (in addition to my Motion 30 center & ML LX16 surrounds) ... I'm running them with a Marantz SR5007 AVR.
During the warmer summer months (anything approaching 75 degrees or more) the SR5007 can and does get quite warm ... it has not, however, gone into protect mode. I bought a small fan from Cool Components (CP - DF) and run it during the warm weather at about 2/3 for movies & TV or 1/2 speed for my classical music and opera videos (too loud @full speed) ... I was also crossing over @ 90db and letting my Dynamo700 help out with the low frequency load ... and, (I'm not sure if it helps or not) bi-amping the Motion 40s.
This summer, having upgraded my sub to dual SVS SB2000s, I'll be crossing over to the subs @100hz to further help out the Marantz SR5007.
But to reiterate, during cooler weather (anything under 70 degrees ... we don't engage the AC much during the summer until the temp exceeds 85 0or so), the Motion 40s/30 4 ohm load and theLX16s' 5 ohms seem to be OK with my AVR.
