MartinLogan Helos 22 [5/24] Lacement

When you first begin to play your speakers, they

will sound a bit bass shy. This is due to the high

quality, long-life components used in the drivers.

Allow approximately 72 hours of break-in at 90

dB (moderate listening levels) before any critical

listening.

Achieving Superior Imaging

These MartinLogan in-ceiling speakers offer superb

imaging and flexible placement in nearly any loca-

tion. However, for best performance and imaging

place speakers equidistant from one another and

avoid physical obstructions between the speaker

and primary listening position.

Balancing Hard vs. Soft Surfaces Improves High-

and Mid-Frequency Performance

Rooms that are “over damped” with carpeting,

drapes, and other sound absorbers can cause

your system to sound dull and lifeless. On the other

hand, rooms can have so many hard surfaces that

the system sounds like a gymnasium. Experiment

by adding or removing soft surfaces until you find

a mix that sounds good to you.

Choosing a Mounting Location

Install the Helos 12 and Helos 22 between ceiling

joists. Be careful to avoid electrical wires behind the

wall and ceiling surfaces.

Balancing Bass Output

Corner placement of these speakers will reinforce

their bass output. If you require balanced output

across the entire audio spectrum avoid mounting

these speakers in a corner.

When choosing placement follow these simple tips:

• Place a minimum of 12” (30cm) from any

wall corner.

• Place front and center channels equidistant

between 10–14 feet (3–4.3m) from the lis-

tening position.

•

Orient the tweeter towards the listening position.
