Mounting guidelines

• Screw hooks support the chains at the ceiling. They must have at least a #10 wood thread

with a shank diameter of at least

through any plasterboard and still have at least one inch (25 mm) of thread left to pene-

trate a wood beam. For a masonry ceiling: use only high-quality metal expansion masonry

anchors that ﬁt the thread of the ceiling hooks.

• Chain: diameter should be at least

• Screw eyes with S hooks attach chains to the speaker and must have at least a #10 wood

thread with a shank diameter of at least

• All hardware (screw hooks, chain, screw eyes, S hooks) must have a manufacturer's safe-

load rating of 40 lb (18 kg) or more.

• Suspend the speakers 18 – 36 inches (45 – 91 cm) from the ceiling; do not mount them

ﬂush to the ceiling.

• To ensure an accurate stereo image, the distance from the ﬂoor should be three to ten feet

(1 – 3.5 m). Be sure the speakers are no less than 18 inches (45 cm) from the ﬂoor. Do not

suspend the speakers exactly halfway between the ﬂoor and ceiling.

If the speakers are more than 10 feet (3 m) from the ﬂoor, we suggest you lengthen the

chain supporting the rear of the speaker. By doing this you will allow the rear of the speaker,

housing eight of the nine drivers, to be angled slightly downward.

1. Ceiling: Anchor at least two screw hooks into a rigid structural ceiling support (beam, joist,

or masonry anchor). Drill pilot holes into wood using a

sary.

2. Speaker: Use the three pre-drilled pilot holes (see Figure 2 - hole set B) on the bottom of

each speaker. Use a

⁄

inch drill bit (3.7 mm) to enlarge the pilot holes to accept the #10

thread screw eyes. Drill to a depth of

completely through the cabinet.
