Although nearfield studio monitors are designed to be more forgiving when it comes to placement, you should do your best to make sure they form an equilateral triangle relative to your head. In other words, make sure that each speaker is equally distant from both your head as well as the other speaker. Once each speaker has been placed, rotate the speakers slightly so that the drivers are pointing toward the listener. Take a look at the diagram on the right. Notice that the distance from the listener's head to each speaker is the same as the distance between the left and right speakers. Also note that the speakers are turned slightly so that the drivers are facing the listener. This is an ideal setup but if it is not practical (or possible) to do this, try to match this setup as closely as possible. Speaker Height The ideal height for M1 Active MK3 is so that the speaker is parallel to the ground and that the midpoint of the woofer and tweeter is at ear-height. The diagram to the right demonstrates the ideal placement height of the speakers relative to the listener. Notice that the listener's ears are directly between the woofer and tweeter. 4 Left Speaker Right Speaker Listener The speakers and listener should be at the three corners of a triangle having equal length sides. tweeter/woofer midpoint
