Placement Make certain the speaker is located between wall studs to avoid cutting into studs. Place the supplied template a minimum of 5/8“ from any studs. Level it and draw a line around it to mark the cutout. Take care when cutting the hole to avoid cutting into pipes or electrical conduits. If you encounter pipes, electrical conduits or other obstacles you may have to select another location for the speaker. Installation First install the frame. Loosen screws A (fig. 1) by turning them counter clockwise. Loosen all 4 screws until the „Dog ears“ B (fig. 2) can move freely. Do not remove the screws. Install the frame into the wall and level it (notice TWEETER and WOOFER markings on the frame). Turn screws A clockwise until they are tightened and the frame is firmly installed. Next install the speaker into the frame. Before installing the speaker connect the speaker wires as described under „Hookup“ and set the impedance switch to the desired position (see “Adjustments”). Remove the grill from the speaker. Place the speaker into the frame and secure with the 6 screws supplied. Before reinstalling the grill on the speaker make tweeter level adjustments as described under “Adjustments”. Reinstall the grill. If the grill has a loose fit and/or is vibrating when the speaker is playing remove the grill, install the supplied non-curing glue strips at locations C (fig. 1) and reinstall the grill. Hookup The receiver/amplifier must be turned OFF before you connect the speaker or it may cause damage to the amplifier. Connect the speaker wires from the receiver/amplifier to the speakers. When connecting the speaker wires make sure that LEFT (L) is connected to LEFT (L), RIGHT (R) to RIGHT (R), POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-). If terminals are color coded, RED is POSITIVE (+) and BLACK is NEGATIVE (-). Adjustments The tweeter can be tilted towards the listening area, due to high frequencies being more directional than low frequencies. The impedance of the speaker and the level of the tweeter are adjustable. IMPEDANCE: Located on the crossover on the back. The factory setting is 8 ohm. If the receiver/amplifier specifies a minimum impedance of 4 ohm, the speaker may be switched to the 4 ohm position. This will make the speaker play louder. When installing more then 1 pair of speakers to a receiver/amplifier special care should be taken to impedance matching the speakers to the receiver/amplifier. This may require impedance matching devices. Consult your dealer for information regarding impedance matching.
