6. When using either Precision 6D or 8D as the main effects speaker for the front soundstage placement is a critical factor for good performance In all cases the centre channel speaker should be placed as close to the viewing screen as possible The viewing position when seated determines the ideal mounting height but in all cases this should be as close as possible to ear height if this is not possible the monitor should be tilted towards ear height in the mix position The centre speaker should be positioned along the centre axis of the picture and the left right monitors just outside the picture ideally the three front effects speakers would be placed with the front baffles in line with the screen surface If an acoustically transparent screen is used the left right monitors should be placed just inside the edges of the picture The surround speakers should be positioned at the same distance to the mix position as the main front speakers As the subwoofer LFE channel only produces low frequencies it is difficult to localise its position by ear As a result it could effectively be situated anywhere in the room though optimum performance will be gained by placing the subwoofer in the same plane as the main front speakers The LFE channel is set at a level 10dB higher than the other channels when mixing therefore it is important to apply the same in any playback situation 6 2 SPEAKER MOUNTING You ve probably got your monitors delicately bal
