Final Installation in New or Existing Construction
cleanly if there is an unseen obstruction behind the wall. BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL EXTRA RESISTANCE AS YOU ARE CUTTING, STOP.
6.If you are cutting into a plaster ceiling, use masking tape to outline your pen- ciled circle and use a razor to score the plaster down to the lath beneath. Then use a chisel to remove all of the plaster within the taped outline. To actually cut the lathe, two methods are used profes- sionally; sawing with a metal cutting blade on a sabre saw is the quickest and the riskiest. Sawing a lathe with a sabre saw can easily vibrate plaster off the ceiling in a completely distant loca- tion creating more patchwork. If you have the patience, use a pair of tin snips to slowly nip away at the lath instead. There is little risk with this method, it is just time consuming.

1.If it is possible to lay a batt of insulation into the ceiling cavity do so. Remember to use equal amounts of insulation for each speaker.
2.Check the position of the Impedance

Jumper on the crossover PC board. Choose the 4 ohm position if you are using an amplifier capable of drawing a 4 ohm load and you have only one pair of speakers connected. Otherwise, use the 8 ohm position (See Figure 15).
3.Separate the speaker wire so that at least two inches of each conductor are free.
4.Open the
5.Insert one unstripped wire fully into the black and one into the red terminal. Pay attention to the markings on the wire. Each speaker must be connected to the amplifier in the same way. If unsure, see “Speaker Phase” located on the fol- lowing page. Squeeze the red and black levers until they click signifying that they have locked into the wire. Check to make sure that the knife assembly inside the no strip connector has prop- erly pierced the wire (See Figure 16).
6.Insert the no strip terminal into the corresponding socket on the rear of the speaker. Push it down until it locks in place. The terminal will only fit in the socket in one direction. If the ter- minal does not properly seat, reverse the terminal
7.On both models, there are four clamps or mounting “dogs” which hold each speaker in place. The dogs are tight- ened via four
