What creates the effortlessness in sound reproduction?


Hello, 
I have a chance to listen some speakers in the last 10 years. I notice that there are 2 speakers which produced sound 'effortlessly', even at low or high volume levels (I never tried max levels on them since they are not mine). With this effortlessness, listening to music is very relaxing. 

I wonder what makes the effortlessness in these speakers? 

Please shed some light on this. 

Thank you.

Not all 6.5 inch drivers are made, measure or perform the same.  Look up the Dali drivers made in house.  No need for 15 inch drivers for effortless sound. It can be done other ways.  Also, products from Perfect Path Audio help greatly in this regard. Many roads to this goal.  
All good points Doug. Many of us don't listen above 75-89db average weighted C when off the leach!
