INTRODUCTION

Thank you for purchasing Sonance ThinLine™ TL and SSTR-series speakers. When properly installed

your new speakers will give you years of entertainment pleasure. This manual will teach you all

about your new speakers’ many innovative features and will show you how to get the very best

performance from them. Please read it thoroughly.

The directions in this manual apply to each model in the series. This manual covers the

following speaker models: TL623R, TL622R; TL621R; TL623SSTR.

DESIGN AND FEATURES

• Thin (77mm) depth allows installation in areas too shallow for conventional in-ceiling speakers.

• Pivoting tweeters direct the sound at listeners for clear sound and improved stereo imaging even when speaker placement options

are limited.

•TL623SSTR reproduces both left and right channels from a single speaker — ideal for small spaces like hallways,closets and bathrooms.

• A 3-position tweeter adjustment switch lets you balance the speaker’s high-frequency energy to better compliment your room’s

setup and acoustics (TL623R/TL623SSTR).

• The RotoLock®mounting system makes installation quick and easy.

•The detachable mounting flange expands installation options, allowing the speaker assembly to be easily mounted in custom cabinetry.

SPEAKER PLACEMENT

TL623SSTR

ThinLine Single Stereo Technology®SSTR speakers are ideal for use in hallways, bathrooms, closets, or in any location where listeners will be moving around

and a pair of stereo speakers would be impractical. The location of the speaker should be determined by considering the primary listening location as well

as aesthetic values. Because a single ThinLine SSTR speaker reproduces both stereo channels from a single location, it will deliver outstanding performance

from an extremely wide variety of mounting locations. For optimum results contact your Authorized Sonance Dealer for advice.

TL623R, TL622R, TL621R

When selecting mounting locations for your speakers you should consider such things as your primary listening location, the primary use for the speakers

(distributed audio, 2-channel stereo or home theater) and aesthetic values. Your local authorized Sonance dealer is an expert in audio/video system

planning and installation. We strongly recommend that you work with your dealer to ensure that your system is properly planned, assembled and installed.

Distributed Audio Speaker Placement (Mono signal)

All Sonance ThinLine speaker models have very smooth and predictable off-axis response, so they provide excellent coverage in distributed audio systems from

a wide variety of installation locations. The chart in

Figure 1

shows how far apart the speakers can be placed at different ceiling heights while still

providing good coverage (as shown in

Figure 2

). The distances are based on ear heights of 62” for standing listeners and 40” for seated listeners.

Home Theater Speaker Placement

Left, Center & Right Channels

• Place the left, center and right speakers from 1 foot to 2 feet in

front of the video screen, anywhere from 6 feet to 10 feet apart,

with the center channel speaker as close to midway between the

left and right speakers as possible.

• The left & right speakers should be at least 2 feet away from the

side walls.

• The main listening position should be between 4 and 10 feet away

from the speakers.

• In some cases pivoting the woofer of each speaker towards the

listening position will help maximize the soundstage, especially

when listening to stereo music sources.

Use

Figure 3

as a guide.

Left & Right Surround Channels (5.1-Channel System)

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. Since the surround speakers are usually called-upon to create diffuse effects like the sound of wind or rain you can mount them close

to walls without adversely affecting sound quality.

• You can create a more diffuse, spacious surround effect by pivoting the tweeters towards a wall or window, away from the listeners.

Use

Figure 3

as a guide.

Left & Right Surround and Surround Back Channels

(7.1-Channel System)

• Left & Right Surround Speakers: Place the left and right

surround speakers directly to the sides of the listening position,

between 6 feet and 10 feet apart. The speakers can be placed close

to the side walls.

• Surround Back Speakers: Place the surround back speakers

between 2 feet and 6 feet behind the listening position. The

surround back speakers should be closer together than the left and

right surround speakers — between 3 feet and 6 feet apart. Like

the left and right surround speakers, the surround back speakers can

be located close to walls without adversely affecting sound quality.

• You can create a more diffuse, spacious surround effect by pivoting

the tweeters towards a wall or window, away from the listeners.

Use

• Place the left and right speakers anywhere from 6 feet to 10 feet apart, with the main listening position as close to midway between the speakers as

possible.

• The speakers should be at least 2 feet away from the side walls.

• The main listening position should be between 4 and 10 feet away from the speakers.

• In most cases pivoting the tweeter of each speaker directly towards the main listening position will help maximize the stereo soundstage.

SELECTING THE PROPER SPEAKER WIRE

For the best sound we recommend that you use premium Sonance

MediaLinQ®speaker cable, which also complies with UL fire rating codes.

You may also experiment with audiophile brands of speaker cable and

interconnects, but be sure to check local codes governing wire that may

be installed within walls or ceilings. Different brands of wire can have

different sonic characteristics, and some may be more compatible with the

sonic “signature” of your various audio system components.

For the best sound you should never use thin-gauge speaker wire – it will

constrict the sound and diminish bass response. 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 thin 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

Figure 5

when selecting the proper wire gauge for your system.

PREPARING THE INSTALLATION LOCATION

Building a Back Box into the Ceiling Bay

Sonance ThinLine speakers are designed to provide exceptionally musical performance in a wide variety of enclosure volumes. You can get the very best

performance from your speakers by partitioning a section of the ceiling bay to form a sealed back box with a specific internal volume. Building such an

enclosure will create a dramatic improvement in your speakers’ bass performance and power handling.

Ideal back box volume requirements:

Insulating the Ceiling Cavity

You can also reduce sound transmission to adjacent rooms and improve speaker performance by inserting a sheet of unfaced fiberglass insulation over the

back of the speaker. To reduce mechanical noise produced by unsupported drywall, install fiberglass insulation in the ceiling bays adjacent to the speaker

location.

Sonafill®

Sonafill (part #91928) is a retrofittable acoustical treatment system consisting of two pillows and four tiles that virtually eliminates noises produced by

resonating drywall. The tiles have pressure-sensitive adhesive and are installed on the back of the drywall on either side of the speaker between the

ceiling joists; the pillows are then stuffed in place behind the tiles. The system dramatically improves midbass sound quality and reduces sound transmis-

sion into adjacent rooms.

INSTALLING THE SPEAKERS

Before Installation: New Construction

For installations in new construction, Sonance recommends using a Symphony FlexBracket (part #92337) to reserve a location for the speaker. The

FlexBracket has perforated wings that can be positioned at any angle around the bracket, and is nailed or screwed to the studs. This serves as a guide

for the drywaller so that the speaker hole will be in the desired location once the drywall is installed.

Before Installation: Retrofit

1. Determine the location for the speaker (see

Speaker Placement

on page 4).

2. Perform an obstruction survey to be certain that there are no studs, conduit, pipes, heating ducts or air returns in the ceiling cavity that will interfere

with the speaker.

3. The cutout for all ThinLine speakers is 85/32” (207mm). There also must be at least 31/32” (77mm) depth within the ceiling cavity.

4. Position the included cutout template where the speaker is to be located and pencil an outline on the ceiling.

• 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 mounting hole using a drywall saw, and run the speaker wires from the mounting hole to the amplifier location.

• Consult local building codes before running speaker wires through walls.

Installation

Sonance ThinLine speakers feature exclusive FastMount®tabs and an integral RotoLock®mounting system for quick mounting directly into existing ceilings

and walls.

WARNING: The edges of FastMount tabs are very sharp. Use caution when handling the speaker.

1. Remove the paint plug from the speaker.

2. Run speaker wire from the amplifier location to each speaker.

3. Strip ¼” – ½” of insulation from each speaker lead. Twist the strands or tin the exposed wire with solder to ensure that there are no stray strands.

SONANCE THINLINE™ TL and SSTR

(Stray strands that touch each other can cause a short-circuit that can damage your

amplifier.)

4. The speaker’s connector posts are spring-loaded. Push the top of each connector post

down to open the connector and insert the exposed wires into the holes in the posts.

(The TL623SSTR has connectors for both the left and right channels.)

• The speaker’s positive post is labeled with a red dot; the negative post is labeled with

a black dot. Double-check that you connected amplifier “+” to speaker “+” and

amplifier “–” to speaker “–”.

5. Make sure all the RotoLock clamps are in the full clockwise position so that they are

tucked within the mounting hole’s border. Insert the speaker into the hole in the

ceiling (

Figure 6

). The RotoLock system can accommodate a maximum ceiling material

thickness of 1¼”.

• The FastMount tabs will prevent the speaker from falling out of the mounting hole, allowing

the installer to let go of the speaker to pick-up tools or other items (Figure 7).

7. Attach the grille after the speaker has been installed. Insert about half of the grille into

the groove at the edge of the speaker. Gently fit the remaining half of the grille by work-

ing around the speaker, fitting the grille into the groove as you go.

PAINTING THE SPEAKERS AND GRILLES

You can paint the speakers and grilles before installing them, which will eliminate the “paint scar” that can be left on the ceiling if the speaker ever needs

to be removed for service. You can also paint the speakers after installation, but before the grilles are attached. All Sonance ThinLine speakers come from

the factory fitted with a plastic ‘paint plug’ that protects the speaker drivers while the mounting flange is being painted.

Sonance always suggests painting the grille separately from the speaker. Before painting, carefully remove the under-grille cloth. It is held in place with a

light tacking glue that makes it easy to remove.

Spray the grilles with thinned paint (5 parts thinner to 1 part paint), being careful not to plug the holes. Too heavy a coat of paint on the grille will

adversely affect the sound of the speaker.

Once the grilles and flange are painted and dry, replace the under-grille cloth, remove the paint plug from the mounting flange and install the grille.

SPEAKER ADJUSTMENTS

Pivoting Tweeter

ThinLine TL623Rand TL622Rhave a pivoting tweeter. This lets you direct sound toward or away from the listening area,

depending on how the speakers are being used:

• If you’re using the speakers in stereo or as the front left/center/right speakers in a home theater, pivot the tweeter

directly towards the listening area. This will help the sound from the speakers blend into a solid soundstage even if

the speakers are widely separated.

• If you’re using the speakers as surround channel speakers in a home theater, you can create a more diffuse, spacious

surround effect by pivoting the tweeters towards a wall or window, away from the listeners.

To Pivot the Tweeter:

Apply light pressure to the plastic ring around the outside edge of the tweeter dome, as shown in

Figure 9

. Do not

touch or apply pressure to the tweeter dome.

Tweeter Level Control

The ThinLine TL623Rand TL623SSTR have a tweeter level control switch (see

Figure 10

) that lets you boost or cut the tweet-

er’s level by 3dB. This allows you to adjust the speaker’s brightness to better match your listening room or personal taste.

Once you have installed the speakers, listen to a variety of music that you are familiar with. If the music all tends to

sound too bright or dull, use the Tweeter Level Control to compensate. If some recordings sound dull and some sound bright

the speaker is accurately reproducing differences in the recordings, and you should leave the control in the middle (0dB)

position.
