Break-In

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.

Speaker Placement

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.
