Sonance THX LCR User Manual

INTRODUCTION
Thank you for purchasing Sonance Cinema Select LCR Cabinet
speakers. When properly installed, these THX-certified speakers will
bring out the best in all your entertainment, delivering film soundtracks
as their creators intended them to sound and reproducing music with
outstanding clarity and realism.
To get the most out of your new speakers, please read this manual
thoroughly before you begin installation.

PARTS LIST

Each Sonance Cinema Select LCR Cabinet Speaker includes the following:
• (1) Cinema Select LCR Cabinet speaker
• (1) Cloth grille
• (4) Self-adhesive rubber feet
ATTACHING THE RUBBER FEET
Peel the adhesive backing from the rubber feet and place them on the
bottom of the speaker as shown in Illustration 1. The feet should be
placed approximately 1" from the cabinet edges.
Note: The Cinema Select LCR Cabinet speaker is designed only for vertical
placement. Laying the speaker on its side will compromise performance.

CONNECTING THE SPEAKER

Run the appropriate gauge wire from your amplifier to the speaker loca-
tions. See Wire Gauge for
the suggested wire gauge
for different wire lengths.
Connect the speaker wires
to the terminals on the
backs of the speakers. (See
Illustration 2.)
Make sure that the speaker
wire polarity is correct:
Speaker '+' to amplifier '+'
and speaker '–' to amplifier
'–' . Proper polarity is par-
ticularly critical to good
speaker performance in
home theater installations.

WIRE GAUGE
Extra resistance in the speaker wire can make a speaker 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 8-ohm
speakers like the Cinema Select LCR Cabinet 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:

SPEAKER PLACEMENT

Placing the Left & Right Speakers
• Place the left & right channel speakers on either side of the video
screen, anywhere from 6 feet to 10 feet apart and 3 – 4 feet from the
floor (which corresponds to the height of your ears when you're seated
on a couch or chair). Use Illustration 3 as a guide.
• If you're placing the speakers inside of an entertainment center or other
furniture, make sure that the speaker's front edges are even with the
front edges of the furniture.
• The main listening position should be between 8 and 12 feet away from
the speakers.

Placing the Center Channel Speaker
• Locate the center speaker as close to the same height as the left & right
speakers as possible. This will maintain consistent tonality between all
3 speakers.
