SPEAKER PLACEMENT

SpeakerCraft highly recommends the use of a qualified custom installation specialist when installing your Starlet speakers. Please

note that all Starlet models require a separate powered subwoofer. In addition, the Starlets 6 and 9 are bi-amplified and require

precise electrical adjustment with a voltmeter and test CD. If this sounds intimidating please consult an expert. You can get

assistance in locating an installation specialist please by contacting SpeakerCraft at 1-800-448-0976.

UNIQUE CHARACTERISTICS OF THE STARLET SERIES

All three Starlet models are the world’s first coincident in-wall line sources. They have acoustical properties that will produce great

advantages in custom installations, but there is one factor that the installer must be aware of when specifying which model to

use and when determining the best listening location.

A pair of Starlets produce a startling and clear stereo image, making a center

speaker unnecessary in many installations. However, the high frequency output

of a line source is only audible to listeners whose ear level is directly in line with

the speaker array. In other words, if a pair of Starlets are installed at seated ear

level and if the listener stands up, so that his or her ears are above the top of

the top speaker, the high notes will vanish. (See Diagram 2) This is the reason

why very long Starlet models are made available. In a large room where people

are going to be listening while seated or standing, the two larger models

(Starlets 6 or 9) are optimum.

By “coincident”, we mean that the acoustic center of the woofer (low frequency)

array and the acoustic center of the tweeter (high frequency) array are lined

up. This means that there are no frequency shifts to the right or left side of the

speaker, and this advantage is why the image produced by the Starlets is supe-

rior to any previous in-wall speaker.

INSTALLATION HEIGHT

SpeakerCraft’s engineers have experimented extensively with the correct height for

Starlets and recommend that the installer determine the listener’s seated ear height.

For the best sonic balance and image, the center of any Starlet model should be

located 5" to 7" above this ear height. (See Diagram 3) In most of the rooms we

have looked at, this means the center of the Starlet should be 48" to 49". On the

Starlet 9, this means the top of the speaker will be about 7 feet high.

In rooms where the Starlets must be higher than this recommendation, it is impera-

tive to make sure that the seated listening position be at least in line with the division

between the lowest and the next-to-lowest driver module. If this cannot be achieved,

use a larger Starlet model.

DECIDING DISTANCE APART

Consider how far apart the speakers should be. To do this, think of your listening area as

a triangle with each leg of the triangle being equal. This equilateral triangle is the most

distance you should have between your speakers relative to the normal listening position.

(See Diagram 4)

CHECKING FOR OBSTRUCTIONS

Before confirming the placement of your Starlet speakers, you should carefully consider

the location of studs, fire blocks, electrical, plumbing and other fixtures or obstructions that

may get in the way. If you are installing the speakers into an existing wall, you can locate

obstructions by noting the placement of wall fixtures and, if possible, gaining access to an

attic or crawl space for further analysis. A good stud finder, found at any building supply

store, will help you determine where the studs are located in the wall.

CLEARANCE NEEDED

Starlets are enclosed speakers that have their own enclosures and do not require any spe-

cific back volume or damping. The enclosure is asymmetrical, a total of 111⁄4" wide. There

is no right or left, but the enclosure measures 6" from center on one side and 51⁄4" on the

other. This will give the installer a little more room on one side if necessary.

(See Diagram 5)

HOME THEATER APPLICATIONS

There are two options for front channel home theater use:

A. Put one pair of speakers VERY close to the screen, and second pair out at the “magic

equilateral triangle” point. The two speakers close to the screen would be wired as the

center channel and the Starlet’s excellent imaging and dispersion will take care of the

rest. (See Diagram 6)

B. Use a Starlet on its side for the center channel. (See Diagram 7)

REAR / SIDE CHANNELS

Starlets make excellent side or rear speakers provided the height installation limitations are

followed.

INSTALLATION CONSIDERATIONS

Prior to the installation of your Starlets, it will be necessary to run cables to the speaker

locations. There are some specific recommendations for the Starlets:

Starlet 4: It is very important to use the heaviest wire in the shortest length possible. 12

gauge or bigger in a length less than 25 feet is optimum. If possible double the cable,

running two sets of 12 gauge to the Starlet 4.

Starlets 6 and 9 are less critical as to wire quality, but still require the largest wire practical.

Volume Control Warning: Performance of all Starlets will be seriously degraded if in-line

speaker level volume controls are used.

INSTALLATION PREPARATION

NEW CONSTRUCTION

Starlets are designed to be installed into a standing wall, therefore no new construction

bracket is supplied.

There are some considerations for new construction to create the best possible sound:

1. Double Thick Drywall: The clamp between the back box and front baffle is designed

for 1⁄2" drywall (or any wall material in 1⁄2"). If you are planning double thick drywall,

leave an area about 12" wide around the Starlet opening in single thickness.

(See Diagram 8)

2. Starlets are Heavy: Walls should be constructed with screws and the wallboard

should be glued to the studs. A few dollars worth of Elmer’s wood glue can work wonders in an in-wall installation.

3. Metal Studs: Avoid these in a wall supporting Starlets

4. Wire Routing: Install the speaker wires before the wallboard goes up (see “SPEAKER INSTALLATION” for wiring information)

FINISHED WALL

When installing the Starlets in a finished wall, please follow these instructions carefully:

a. Determining Placement: See “SPEAKER PLACEMENT” on pages 3-4.

b. Locating Obstructions: See “Checking for Obstructions” on page 4.

c. Tracing the Cut-Out Template: Your installation cut-out template is included in the packaging. Please be aware that there

are two sections: one is the cut-out template and the other is the paint mask. Be careful not to confuse the two. Place the

cut-out template at the location you have decided to install the Starlets. (See Diagram 9) Keep in mind that the flange will

extend beyond the cut-out on the sides, top and bottom.

The cut-out takes into account the asymmetrical shape

of the Back Box/Driver Assembly. This gives a small

degree of lateral freedom when installing the 111⁄2" wide

Back Box/Driver Assembly into a

typical 141⁄2" wide stud bay. There is no real “up” or

“down” to the Starlet, so use the cut-out template to

determine the best position for the speaker in order to

avoid obstructions and to get the best acous- tic

results. There is a correct way to install the baf- fle

assembly, however, which is covered in the next sec-

tion, “SPEAKER INSTALLATION”.

With the above in mind, use a level along the top or

bottom edge of the template so that the cut-out will be

aligned correctly. Use tape or tacks to hold the tem- plate

in place. Trace an outline of this pattern on the wall with a

pencil. (See Diagram 10)

SPEAKER INSTALLATION

All Starlet models install in the same way. The wiring for the Starlet 4 differs from the bi-amplified Starlets 6 and 9. There are

different procedures for mounting in a standard stud depth (2x4 framed wall) and deeper walls (2x6 or deeper). The supplied

foam support block is intended for deeper walls.

The installation of Starlets is straightforward, but it is more difficult than smaller in-walls and following these directions is very

important. Of course, the final result is the best performance available from an in-wall loudspeaker so it is worth the extra effort.

WIRING THE STARLET 4

All Starlets have binding post terminals on both ends of the back box. In the case

of the Starlet 4, they are electrically identical, and allow the connection of wire to

whichever end is easier. Optionally, they allow for bi-wiring by running parallel

wires to each end of the speaker. As mentioned previously, heavy gauge wire in

the shortest length possible is needed for the Starlet 4. (See Diagram 14)

Page 6 Starlet Owner’s Manual

d. Cutting the Hole

CAUTION: This is the most important part of the entire installation. If you are not

certain whether or not an obstruction exists behind the desired mounting area, you

should conduct an obstruction survey by cutting small holes every 10" or 12" in the

center of the cut-out area. Cut at a 45˚ angle towards the inside of the hole. Cutting

the small hole at this angle will make drywall repair much easier as the piece cut out

can be re-installed neatly back into the hole (in the case the location is not suitable).

Once you have determined that there are no obstructions in the desired mounting

area, start cutting the hole at a 90˚ angle to the wall surface. (See Diagram 11)

e. Installing the Bracket

The Bracket comes in two pieces - Outer Bracket and Inner Bracket. The Outer Bracket

should go on the outside of the drywall, and the Inner Bracket should go inside the

drywall. Along the lower edge of the drywall cut-out, use the Outer Bracket as a template to mark the screwholes with a

pencil. Drill two clearance holes for the mounting screws. The screws pass through the Outer Bracket and drywall and

tighten into the Inner Bracket. (See Diagram 12)

Once assembled, the completed bracket will form a shelf to prevent the Back Box/Driver Assembly from falling into the wall

cavity. (See Diagram 13)

WIRING THE STARLETS 6 and 9

The Starlets 6 and 9 are bi-amplified, which means that one terminal is wired to

a single amplifier channel and the other terminal is wired to a separate amplifier

channel. Thus both terminals are always used in the Starlets 6 and 9. The end plate

bearing the SpeakerCraft logo and product name is the woofer terminal, and is

marked “woofers”. The blank plate is the tweeter terminal, and is marked “tweeters”.

(See Diagram 15)

There are two options for bi-amping:

1. Use a single stereo amplifier for each speaker, with one channel for the woofer

and the other for the tweeter. This option is preferred if you have two identical

stereo amplifiers.

2. Use one amplifier for the woofers and a separate amplifier for the tweeters. This

option is preferred if you have two different stereo amplifiers. In this case, the

less powerful amplifier should be used on the tweeter section.

INSTALLATION IN A 2x4 STUD WALL

All Starlets are asymmetrical. Hold the Back Box/Driver Assembly by grasping

the tweeters, being careful not to touch the voice coils behind the tweeters.

The tweeter assembly is very strong, as the tweeter bridge is a cast aluminum

part. On the larger Starlets, it is advisable to have an assistant. Insert the long

side of the back box first, pushing it until the tweeter bridge stops further move-

ment. Then slip the short side into the cavity, moving the Starlet until the tweeter

bridge is centered. The proximity of the back wall will support the speaker while

the rest of the installation is completed. (See Diagram 16)

The Bezel/Flange Assembly is installed into the Back Box/Driver Assembly,

forming a strong clamp with the wall. Please observe that there are “tabs” on the

back of the Bezel/Flange Assembly that fit into corresponding slots on the baffles.

They only fit one way, which is indicated by small arrows on these two

parts. Use the supplied M4 x 45mm hex head screws to secure the Bezel/Flange

Assembly into the Back Box/Driver Assembly. For your convenience, we’ve

enclosed the correct sized hex driver in the supplied Accessory Pack. It is strongly

advised that you use a power screwdriver to save time and get a tight fit. Make

sure all of these hex screws are firmly seated. (See Diagram 17 on page 8)
