5 feet from the floor. Center
the speakers on the listening
location.

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.

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
