Selecting the Proper Speaker Wire

SONANCE THINLINE™ TL and SSTR

Stereo (2-Channel)

•Place the left and right speakers anywhere from 6 feet to 10 feet apart, with the main listening position as close to midway between the speakers as possible.

• The speakers should be at least 2 feet away from the side walls.

• The main listening position should be between 4 and 10 feet away from the speakers.

• In most cases pivoting the tweeter of each speaker directly towards the main listening position will help maximize the stereo soundstage.

Use the left and right speaker placement in Figures 3 and 4 as a guide.

PREPARING THE INSTALLATION LOCATION

Building a Back Box into the Ceiling Bay

Sonance ThinLine speakers are designed to provide exceptionally musical performance in a wide variety of enclosure volumes. You can get the very best performance from your speakers by partitioning a section of the ceiling bay to form a sealed back box with a specific internal volume. Building such an enclosure will create a dramatic improvement in your speakers’ bass performance and power handling.

Ideal back box volume requirements:

ThinLine	TL623R:	1.5	ft3	ThinLine	TL621R:	1.0	ft3
ThinLine	TL622R:	1.2	ft3	ThinLine	TL623SSTR:	1.5	ft3
