loudspeaker. When matched to comparable electronic

equipment, expect years of quality high delity sound. Our

belief is that music matters and we are focused on delivering

superlative music reproduction everywhere in your home.

The following manual is designed to give you, the installer or

owner, basic information as to the speaker’s installation and

operation. It is beyond the scope of this manual to go into all the

details that must be taken into consideration in a sophisticated

high delity system. When installing the wiring and speakers it is

important to adhere to all local codes and regulations. Consulting

a professional will help to maximize your system’s performance.

If you have any questions that are not answered by this manual,

Each speaker is thoroughly tested before it leaves the factory.

However, in shipment, accidents may occur. Please inspect your

speakers carefully when you receive them to make sure there

is no damage. If there is, please notify your dealer, or supplier

immediately for assistance. If you received your speakers by

public transportation, report the damage at once to the shipping

company.

These speakers will perform well with ampliers from 5 to 125

Watts RMS. However, damage to the speakers can be done by

ampliers of nearly any power rating if the amplier is overdriven

into clipping. “Amplier clipping” is a phrase used to describe

a condition when, because of the volume demand, an amplier

is being asked for more power than it can give. Clipping causes

distortion of the audio signal. If you should hear an unusual

amount of distortion at high listening levels then consider

reducing the volume. DAMAGE DONE TO A SPEAKER BY CLIPPING

IS NOT COVERED UNDER THE WARRANTY.

This speaker was designed and engineered to provide the nest

performance achievable in a compact package. The custom

waveguide is unique in the industry and provides cross-axis

performance that gives every listener in the room a sense of

envelopment unmatched by other speakers in this category.

By focusing the sound eld across the listening space, the

listener experiences a more balanced and symmetric sound level,

especially when the main speakers are spaced more closely than

is ideal, (common in many of today’s home theaters).

The waveguide also increases the

efciency of the tweeter, allowing it

to operate with far less input power

and signicantly lower distortion.

This same waveguide also allows the

tweeter to operate a full octave lower

than conventional dome tweeters. This

allows the tweeter to cover more of the

critical voice range.

This same cross-axis tweeter design

creates a much smoother off-axis

listening experience, eliminating the

midrange-hole that is commonly

experienced with conventional

designs. Additionally, by controlling the

directivity of the sound eld, the early

reections that occur from nearby walls

and furniture are reduced so that more of the direct sound from the

speakers are heard, improving the intelligibility and detail of the

original sound source.

Finally, the inset tweeter produces a time aligned position and

excellent phase coherency with the woofer, improving the off-axis

performance, both in the vertical and horizontal directions.

This speaker can be used for 2-channel High Resolution audio

or for nearly any speaker location within a home theater system.

The following chart provides suggested tweeter orientations for a

number of common speaker locations within a home theater. We

encourage you to experiment with the tweeter orientation to see

what works best within your system, especially with surround

placements.

While it may seem unconventional to use this speaker in the

Landscape orientation for the center dialog speaker, it is actually

well suited because of the excellent phase coherency between the

tweeter and woofer. The speaker actually outperforms most of MTM

(Mid-Tweeter-Mid) designs that have become commonplace for the

center dialog channel.

• The tweeter should be rotated into the desired position for optimal

performance.

• There are detents every 15 degrees. The tweeter will lock into these

detents when positioned over them.

• Press rmly at the edge of the tweeter waveguide using 4 ngers.

• A gap of about 2mm will appear at the edge when depressed.

• Rotate the tweeter into the desired position, releasing when you

feel a detent.

avoided as it is not as durable. Allow about 2½ feet (0.8m) of free

cable at the speaker cut-out and sufcient length at the other end

to reach the electronics. Having to add extra cable later can be

tedious and time consuming.

Avoid bundling speaker cables parallel to electrical cables for

extended lengths. Though the impedance is low and the likelihood

of interference low, this may help reduce hum and RF interference.

When securing the cable, use care not to staple or nail through the

electrical conductors. Doing so could result in a short that might

damage the electronics.

When connecting your speakers, make sure proper polarity

(phasing) is maintained. Simply put, this means ensuring the

same wire which is connected to the positive terminal of the

amplier has its other end connected to the positive terminal of

the speaker. It is important to check this on all speakers. If the

connections on one of the speakers are reversed, (out of phase)

the sound quality will be impaired.

If the drywall has not yet been installed a Rough-in-Bracket (RIB-

LCR) may be used to reserve the speaker location on the wall.

The RIB-LCR brackets are available from the distributor or dealer

where the speakers were purchased. When these brackets are

used the holes are cut when the drywall is installed. The cable can

be tied off on the bracket after securing the cable to a nearby joist.

If the drywall is installed and the speaker locations have not yet

been established, then do so now. Assess the wall for possible

concealed obstructions such as wiring, plumbing, etc. Inspect the

backside of the wall, the attic, and/or the crawl space if available

for clues to possible obstructions. Use inspection holes with

inspection tools (camera, mirror, ashlight, etc.) if absolutely

necessary. Use a “stud nder” to locate the positions of the studs.

Once the speaker locations are established

use the cardboard template (the outside

of the inner cardboard rectangle) to mark

the speaker cut-out. The dimensions for

the cut-out are listed in the chart on the

previous page. Using the proper tool, cut

the appropriate sized hole in the wall.

On drywall, clean cuts can be made with

a drywall saw. Cut-out dimensions are

included on the 1st page.

If the cable has not yet been run, do so now

that you have access to the wall’s interior.

To aid in speaker performance, a brous

material, such as berglass, may be

placed behind the speaker. This may

also help to reduce unwanted sound

from being transmitted into adjoining

rooms. If the wall space has blown or

loose insulation, care must be taken

to prevent the loose insulation from

entering the back of the speaker. This

can be accomplished by placing a batt

of berglass insulation behind the back

of the speaker.

The grilles can be painted using multiple light coats of spray paint.

Custom color spray paints are available from specialty companies.

Contact your dealer for more information. The grilles should be

removed from the speaker and painted in a clean environment to

prevent contamination. It is best to go around the grilles and apply

the paint from multiple angles. DO NOT remove the scrim cloth

from the backside of the grille. It is not replaceable.

Attach the grilles to the speakers and enjoy. Should you wish to

remove the grilles from the speakers pull at the grilles' corners.

Initially there will be signicant resistance because the grilles are

magnetically attached.

• NOTE: It may be necessary to moisten one's ngers to achieve

good traction on the waveguide.

• The detents will not be felt when the waveguide is fully

depressed. Decrease pressure to locate the detents.

If after reading this Installation Guide you are uncomfortable

with the planning or installation process then please contact

a professional for assistance. Placement of In-wall speakers

should be carefully considered and it is beyond the scope of

this publication to discuss all of the various aspects of speaker

placement but here are some helpful suggestions.

Ideally, the speakers should be located where they will provide

the best possible sound and ease of installation. When used

in a home theater or 2-channel high resolution audio system,

the front left and right speakers should be ear level, or a little

higher, and separated from each other a distance of 0.75x to 1x

the seating distance. For example, if the seating position is 10

feet from the wall where the speakers are to be installed, then

ideally the distance between the left and right speakers should be

somewhere between 7.5 and 10 feet, (Ex. 0.75 x 10ft = 7.5ft). If the

speakers are located behind an acoustically transparent screen

then all the speakers should be oriented portrait style. The tweeter

should be aimed toward the listening area. For other tweeter

positions see the tweeter positions chart to the left.

Placing the speakers within 18 to 36 inches of an adjacent wall,

as measured to the center of the speaker, will tend to increase

the effective bass output. Avoid placing the speakers less than

18 inches from an adjacent wall. When placing speakers near

a corner, avoid locating them an equal distance from the two

adjacent surfaces.

To achieve maximum performance we recommend that the

speaker cable be at least 16 gauge or larger for runs over 50 feet

(15m) and that the cable be double insulated. A CL-2 or CL-3 rated

cable may be required. Check local codes. “Zip cord,” which is

single insulated and is often made with clear insulation, should be
