Speaker Installation Locations When selecting installation locations youmust takeinto account both mechanical and acoustical factors. The pivoting tweeter of the PRi665 and PRi685 helps them produce excellent sound even when they are installed in less than ideal locations. The mechanical factors have to do with the structural parts inside the ceiling. If youar e installing the speakers in new construction it is easy to take this into account. Simply select the installation locations

Divide this by 3 = 4.75 or 4 steps. This is thenumber of tap settings to lower the system by – so we will use8W taps. (Note that this system already has dB of headr oom more than the 6” system.) As this is a rule ofthumb, you will need to testthe SPL in the room to determinethe pr oper tap setting. If you want morehead room on the amplifier, set the taps to 16W.
