Sonance ultra ii lcr User Guide

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 4 and Illustration 5 as a guide.

• If you’re placing the speakers inside of an entertainment center or other

furniture, bring the speakers all the way to the fronts of the openings so
their 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

• You can orient the center speaker horizontally or vertically. See

Orienting The Speaker for details.

• Locate the center speaker as close to the same height as the left & right

speakers as possible. This will help maintain consistent tonality
between all 3 front speakers.

• If you must place the center speaker above or below a video screen, we

recommend placing it no more than 2 feet above or below the 
center of the left and right speakers. Use Illustration 4 and Illustration 5
as a guide.

• If the center speaker is placed above or below ear level, angle it up or

down so it is aiming directly at the listeners. Use a pair of rubber door
stops or similar to elevate the speaker’s bottom edge as required.

Tweeter Level Adjustment

In most rooms Cinema Ultra II LCR Cabinet speakers will sound 
best with the tweeter adjustment in the ‘Flat’ position. However, if the
speakers sound too bright in your room, set the Tweeter Level switch to
the ‘–3dB’ position. If the sound in your room is too dull, set the switch
to the ‘+3dB’ position. (See Illustration 3.)

Woofer Boundary Compensation Adjustment

Placing the Cinema Ultra II LCR Cabinet speaker on top of a TV or in a
book case can increase the speaker’s bass by as much as 6dB in the 
65Hz – 200Hz range. This can affect the naturalness of music, and make
male voices sound thick and heavy. (You can determine this by playing
pink noise through the Left, Center and Right speakers and noting any 
tonal differences between them.) If any of the speakers is affected this
way, set the Woofer Boundary Compensation switch to the ‘On’ position
to reduce its output in the 65Hz – 200Hz range. (See Illustration 3.)

CLEANING THE SPEAKER

Clean the cabinet with a damp cloth. Do NOT use liquid cleaners 
or aerosol sprays, as they may permanently damage the finish. When
cleaning the baffle panel, be especially careful not to touch the speaker
drivers.
