[. . . ] The mechanical factors have to do with the structural parts inside the ceiling. If you are installing the speakers in new construction it is easy to take this into account. Simply select the installation locations before the wall board goes up. First, you must know the locations of the ceiling rafters to be sure the installation location is between them. [. . . ] If you are using the speakers without a subwoofer, leave the highpass filter switched off. However, if the speakers will be used full-range in high sound level applications, using the highpass filter will help protect the speaker. If you are using a dedicated subwoofer in your installation, switch the highpass filter on. For new construction installations, we offer new construction brackets. It serves to control the distribution of the amplifier power to the various speakers and correspondingly can be used to balance the relative output of the speakers. There is also a "Dir" bypass setting should you want to connect the speakers to a conventional amplifier at some point in the future. The total of the power level selected with the switch settings, plus a 20% "transformer loss factor" will tell you if the amplifier has enough power for the configuration. For example, say you have 6 speaker on a given amplifier channel, three with the transformer set to 15 watts and three set at 30 watts. 2 = 162 watts As long as you have that much power available then you can drive the combined speakers properly. It you set all six of the speakers to the 30 watt setting then you would need 216 watts: (6 x 30) x 1. 2 = 216 Once you are satisfied with the transformer switch settings press the speaker grilles into place to complete the installation. Always turn off the amplifier or receiver when connecting speakers or any other components to the system.

Insert a long, bent piece of wire and rotate to confirm that there are no obstructions behind the chosen location. Open up the clamp and insert about 2" (50mm) of wire through the opening. Note: If there is a jacket around the two wire conductors fasten the clamp to the jacketed part of the wire. Remove the jacket from the part of the wire that extends beyond the clamp. Just before the speaker is mounted plug the connector into the back of the speaker. Finally rotate the cover plate into position and tighten the fasteners to hold it in place. It is important that all the speakers in a system are hooked up with the same polarity or "in phase. " Instead of the wire terminals typical of most speakers, the HSi 430CV and 435CV models are supplied with a Molex plug-in connector to facilitate installation.
