Each LFR1500 will have 7 driver arrays hence the need for 14 channels of amplification. The LFR1900 will require 18 channels.

One of my buddies was over last night to listen to the M2OW and actives. He's also familiar with the M3 and M50 sound. His mind was shattered to discover what these diminutive speakers are capable of. In his words, the M2s are not as detailed as the actives but more detailed than M3s or M50s. This quality makes them very enjoyable with no listening fatigue.

My terribly dimensioned living room with what I thought was an acoustically horrible bow window has been consecrated with the M2s and is now hallowed ground.
