Installation The Installation section describes: • Installing the SF 26X in a Suspended Ceiling • Painting the Baffle and Grille Installing the SF 26X in a Suspended Ceiling 1. Remove power from all devices. NOTE: If the baffle or grille is to be painted, see the Painting the Baffle and Grille section on page 12. The maximum ceiling tile thickness that the speaker can go into is 1.22 inches (31 mm). 2. Cut a hole for the SF 26X. Use the provided cutout template to outline the hole to be cut

6. Attach speaker wires from the ceiling tile hole to the included four-pole captive screw connector using one of the following three methods below. NOTES: • Be sure that the combined impedance of the speaker system does not equal a value less than the rated minimum load impedance of the amplifier. • The maximum number of wires per terminal are as follows: Wire Gauge Table Maximum Number of Wires per Connection Point Wire Gauge 1 12 AWG 2 16 AWG • D

• Wiring Multiple Speakers Using Loop-through: A loop-through electrical connection is made on the crossover board of the SF 26X. Connect the wires to the captive screw connectors of the speakers, as shown below. Be sure to tighten the screws. NOTES: • Be sure that the combined impedance of the speaker system does not equal a value less than the rated minimum load impedance of the amplifier. • When a chain of speakers is wired in this configuration, disconnecting one speaker removes

Painting the Baffle and Grille NOTE: The cutout template that was used in step 2 of the previous section will be used as a paint shield when painting the outer circumference of the baffle. Painting the Baffle 1. Remove the grille using the provided grille hooks and set the grille aside. 2. Place cutout template over the center of the tweeter so that the woofer and tweeter of the speaker are protected from the paint. 3. Tape over the center hole of the template to prevent any paint from enterin
