Wire Gauge, Installing the Speakers, New Construction

Surround Back Channel Speakers

The surround back speakers in a 6.1- or 7.1-channel system should be placed on the rear wall of the listening room at the same height as the left and right surround speakers. Place the speakers from 4 feet to 8 feet apart.

Use Illustration 4 as a guide.

4' – 8'

5' – 7'

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 Selects, 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

Distance in Feet	50'	100'	150'	200'	250'	300'

20 gauge	1.04	2.07	3.11	4.14	5.18	6.22

18 gauge	.65	1.30	1.96	2.61	3.26	3.91
16 gauge	.41	.82	1.22	1.63	2.04	2.45
14 gauge	.26	.52	.77	1.03	1.29	1.55
12 gauge	.16	.32	.49	.65	.81	.97
10 gauge	.10	.20	.31	.41	.51	.61

Note: This enclosure is not retrofittable and must be installed in new construction only.

Sonafill® Resonance Cancellation System

To reduce sound transmission to adjacent rooms and improve speaker performance when a Symphony wood acoustic enclosure cannot be used (such as in a retrofit installation), Sonance recommends installing the Sonafill® in-wall resonance cancellation system (part# 91698) in each speaker’s wall cavity. Sonafill utilizes acoustic damping tiles and acoustic absorption pillows to cancel drywall vibration and reduce the resulting coloration of the speakers’ sound. The Sonafill system can be easily retrofitted into existing walls.

INSTALLING THE SPEAKERS

New Construction

For new construction installations without Acoustic Enclosures, Sonance recommends using a Symphony FlexBracket (part#92901) to reserve a location for the speaker. The FlexBracket is nailed or screwed to the studs and serves as a guide for the drywaller so that the speaker hole will be in the desired location once the drywall is installed.

Symphony FlexBrackets are compatible with the RotoLock mounting system (see Retrofit, below).

Illustration 6 shows a FlexBracket installation example:

Sonance Cinema Select Speakers feature an integral RotoLock™ mounting system for quick mounting directly into existing walls. Once the hole is cut and the cable is run, you can install the speaker in a matter of seconds.

1. Determine the location for the speaker (see Speaker Placement).

2. Perform an obstruction survey to be certain that there are no studs,

conduit, pipes, heating ducts or air returns that will interfere with the

speaker.

3. The cutout for the Cinema Select LCR and SUR speakers is 71/16”

(179mm) x 11¼” (286mm). There also must be at least 37/8” (99mm)

depth within the wall cavity for the speaker.

4. Find the cutout template provided in the speaker packaging. Position

PREPARING THE INSTALLATION LOCATION

Symphony Acoustic Enclosures

Although Sonance Cinema Select speakers are designed to be relatively insensitive to variations in enclosure volume, you can achieve the ultimate performance by installing a Symphony Acoustic Enclosure (part# 91688) for each speaker. This fully- braced enclosure is made from ½” MDF, and will deliver free-standing speaker per- formance from Cinema Select in-wall speakers.

the template where the speaker is to be located and pencil an outline

on the wall.

• If you are unsure about obstructions, drill a small hole in the center

of the outline and insert a coat hanger wire into the hole to

feel-around for possible obstructions.

5. Cut the speaker hole using a drywall saw, and run the speaker wires.

6. Remove the paint plug from the speaker. Connect the speaker wire to

the terminals on the back of the speaker. Make sure to connect the

amplifier ‘+’ to the speaker ‘+’ and the amplifier ‘–’ to the speaker ‘–’.
