(see “Environmental capabilities”, page 9). Unpacking the carton Carefully unpack your Free Space 51 speakers and save all packing materials for possible future use. Check that your system contains all parts identified in Figure 1. Do not attempt to use your speakers if any components are missing or appear damaged.
• Do not place your speakers in an area where water tends to collect. • Do not bury your Free Space 51 speakers deeper than 7 1/4 inches (18.4 cm) (Figure 3a). • Place 2 - 4 inches (5 - 10 cm) of crushed rock or gravel at the base of the hole to allow for water drainage.
1. Connect the speakers on the left side of the listening area to the left channel of your receiver/amplifier (Figure 6). 2. Connect the speaker on the right side of the listening area to the right channel of your receiver or amplifier, as above.
Connecting cord to receiver Checking the connections Check the speaker connections carefully. Make sure no loose strands of wire touch across terminals. This could create short circuits and damage an amplifier or receiver. Tighten any loose connections before you plug in the receiver/amplifier.
Use a cloth dampened in mild detergent and water to remove dust or dirt from the outside of your Free Space 51 speakers. Or use a hose to rinse them thoroughly with fresh water. Do not use enough pressure to force water into the drivers or the acoustic ports.
Protecting the speaker cord The bare ends of the speaker cord can be affected by exposure to the elements. This is espe- cially true of salt water or water containing chemicals such as chlorine or fertilizer. You may use a silicone caulking material, such as RTV adhesive, to protect the connections. It is com- monly available at hardware stores.
