5. ONITORING POSITION SHOULD BE EQUAL Notice that Figure 1 also shows the speaker cabinets turned inward directly facing the listening position This puts you in the sweet spot which yields the most accurate stereo reproduction If you need a wider sweet spot to allow for greater listener movement or for group monitoring face the speakers in a slightly more open position but never more than necessary Finally if you must mount the speakers substantially above or below ear level then you will also need to tilt the cabinets downward or upward as well to keep them directly facing you Once you start using your Event monitors you may find it helpful to move around in their soundfield to locate their best position in your environment but if you follow the equal distance ear level face on rules you ve already optimized their position for a single user in most situations 20 20 CONNECTIONS TO AN EXTERNAL POWER AMPLIFIER The passive Event 20 20 monitors present a 4 ohm nominal load impedance to the amplifier Amplifiers rated for 8 ohm minimum loads are generally not suitable and may even suffer damage if used We recommend using a power amplifier rated in the range of 100 200 watts per channel into 4 ohms Higher power amplifiers can be used with caution but care must be taken to never exceed the 20 20 monitor s 150W program 200W peak ratings Event is not responsible for damage caused by overpowering the speaker s components Connections
