• You can create a more dif- fuse, spacious surround effect by pivoting the Sonic Eye away from the listeners.

Use Illustration 2 as a guide.

Rear wall mounting: The lis- tening position should be 2 – 10 feet in front of the rear wall. Locate the surround channel speakers on the rear wall, 6 – 10 feet apart, at least 5 feet from the floor. Center the speakers on the listening location.

• You can create a more dif-

fuse, spacious surround effect by pivoting each speaker’s Sonic Eye towards a wall or window, away from the listeners.

Use Illustration 3 as a guide.

Ceiling mounting: Locate the left and right surround speakers on the ceiling between 2 feet and 6 feet behind the listening position. The speakers should be between 6 feet and 10 feet apart, with their woofers towards the listeners.

•You can create a more diffuse, spacious surround effect by pivoting each speaker’s Sonic Eye towards a wall or window, away from the listeners.

WIRE GAUGE

Extra resistance in the speaker wire can make speakers sound less dynamic and reduce definition of the bass frequencies. In extreme cases, it can even attenuate high frequencies. Also, amplifier power is wasted in wire with extra resistance, reducing your system’s maximum output level.

To prevent degrading sound quality, the total wire resistance should be less than 10% of the speaker’s impedance. This means that for an 8-ohm speaker, the total resistance of the wire should be less than 0.8 ohms.

Refer to the following table when selecting the proper wire gauge for your system:

Wire resistance in Ohms vs. length of cable run
