IMPORTANT NOTICE

All new speakers require a minimum of 60 hours break-in-time before
they sound the way they are supposed to. A speaker's performance improves significantly
once broken in. It is critical that you have at least 60 hours on your speakers before you
evaluate them. Don't worry if your speakers do not sound perfect the first time you play
them. This is normal until they are broken in. If you are having difficulty getting enough
hours on your speakers and your 30 day return privilege is getting near, call us. We will
work with you. Please give us the courtesy of breaking the speakers in before you
determine they don't sound right.

Many of our customers break their speakers in by:
A) Leaving them on at moderate listening levels when they are not home.

B) Leaving them on at moderate listening levels while they sleep.
C) Running pink noise through them.

These methods are not convenient for everyone and we understand this. But
please know that you are not giving yourself, your speakers or us a fair chance if you do
not break them in before critical evaluation.

THANK YOU!

The Emerald

Thank you for your order and congratulations on becoming the owner of an Audio Concepts, Inc. (ACI)
speaker system. The Emerald is an audiophile quality system that will provide you with many years of
listening pleasure! Be sure and take a moment to register your warranty later in this manual.

About the Emerald

The Emerald is derived from the proven AV1. ACI's design philosophy has always been to build speakers
that bring the music to life. Introduced in 1990, the AV1 was the first audiophile quality video-shielded
speaker ever manufactured. Proven by sales and longevity, the AV1 satisfied audiophile needs for many
years. When in late 1997 the AV1’s tweeter was discontinued ACI saw an opportunity to revise the AV1
design with an improved soft-dome tweeter. The Emerald is the perfect speaker for high-end home theater,
yet is one of very few shielded speakers with the sound quality required for stereo music use. The Emerald
makes a terrific improvement in a home theater system. The specially designed drivers allow placement
right next to, on or under TV screens without damaging the screen or hurting the video picture.

Most speakers sold for center channel use are wide and flat with a center-mounted tweeter flanked by
woofer-midranges on either side (MTM). This type of speaker has a dispersion pattern, which actually
increases floor and ceiling reflections while having poor dispersion to the sides!

4

The Emerald is a very unique speaker system. Instead of using the non-optimum horizontal approach, the
Emerald boldly utilizes a vertical driver arrangement to produce a well-controlled vertical dispersion pattern
which minimizes reflections and colorations from the room surfaces while maximizing clarity at the listener’s
ears. The Emerald has excellent horizontal dispersion so that listeners seated center, right or left all get the
same high quality sound. The unique vertical design and specialized crossover of the Emerald makes this
possible.

The Emerald is compact enough to fit vertically under or on top of most TVs. If you must position it
horizontally you may do so. Even positioned horizontally, the sound quality will be better than most
horizontal MTM designs.

The excellent sound quality and dynamic range of the Emerald make it perfect for stereo listeners requiring
“big” sound from small boxes. Videophiles seeking a compact but very high quality system should consider
Emerald for left, right, center and rear channels. For the ultimate bass extension, the Emerald mates
beautifully with the Titan or Force powered subwoofers. Add a pair of Atlantis or Sanus Speaker stands for
best placement and imaging. The Emerald may also be shelf or wall-mounted.

Design philosophy for the Emerald

Modern speaker design is a combination of science, art and sweat. A successful design such as the
Emerald requires thousands of hours utilizing computer modeling, several generations of prototypes,
precision testing, critical listening and many "fine tunings".

Our design goals for the Emerald were to produce a small, attractive speaker with smooth,
uncolored, wide-range response, three-dimensional stereo imaging, good sensitivity, high power handling,
and the ability to convey the "soul" of the music. The Emerald also had to use specially developed, fully
shielded drive units to allow placement right next to, on top of or under a television set or video monitor. The
Emerald had to be extremely linear in the midrange with controlled dispersion to provide optimum speech
intelligibility for video dialog, (center channel) applications. Although designed for excellent bass response,
the Emerald had to be easily adaptable for use with subwoofers. We are pleased to have achieved and in
some areas exceeded our goals by systematically engineering the Emerald to optimize performance. Please
note the following factors:

Frequency Response:

For a speaker to be considered "accurate" it must have a smooth frequency response that is free of
major dips, peaks, troughs or plateaus. The Emerald exhibits exceptionally flat response; ± 3db from 65Hz
to 20Khz and better than ± 1.5db from 100Hz to 10kHz! The cast-frame woofer combined with a computer
derived rear vent, provides exceptional bass performance for a speaker of this compact size.

Of nearly equal importance is the off-axis response of the speaker. This response from 15 to 45
degrees off the axis of the speaker determines the smoothness of the early reflections from the wall
surfaces. In video applications the off-axis response characteristics are extremely important for accurate
voice and special effects reproduction. In most domestic listening situations this energy is nearly equal to
the on-axis response in determining the balance of the system. The off-axis response should show a
gradual decrease in output with increased frequency. The Emerald had an exceptionally well controlled off­axis dispersion pattern.

Tight quality control procedures are necessary to assure that your Emeralds sound every bit as
good as our lab samples. Incoming shipments of raw parts including cabinet materials, drivers and
crossover components are subject to extensive testing to verify that they meet our exacting standards.

Dynamic range:

Dynamic range in a speaker requires ;

• Adequate sensitivity so that it may be driven to realistic levels with available amplification. The C-

weighted sensitivity for the Emerald is 88db which is considerably better than other speakers this size
with this quality of bass response! The Emerald will not have to be driven as hard as less efficient
monitors.

• An easy load for the amplifier. A speaker can have a high sensitivity number but may present a difficult

load for the driving amplifier. The impedance curve of the Emerald never drops below 6 ohms and is an
easy load for any receiver or amplifier.

• Low distortion drive units are necessary to keep the music from becoming edgy or gritty as the volume is

turned up. The drive units used in the Emerald have very linear suspensions to reduce distortion
components to inaudible levels and contribute to the excellent sense of "clarity". The crossover used
keeps low frequencies out of the tweeter and protects it from over-excursion at resonance, which would
otherwise cause increased distortion.

Good power handling is a requirement if musical peaks are to be reproduced cleanly and without damage to
the speaker. The woofers used in the Emerald are extremely rugged. The utilization of a precisely tuned
tapered rear vent yields significantly better dynamics than most speakers this size. The Emerald uses a very
high-quality, fully shielded silk-dome tweeter by Vifa of Denmark. This dynamic tweeter provides excellent
damping, smooth crossover transition, and excellent power handling.

6

Delayed Resonance Control:

The ultimate control of delayed resonance required extensive use of Cumulative Spectral Decay
analysis coupled with accelerometer testing of the cabinet wall surfaces. This extensive testing allowed us to
develop the most cost-effective internal bracing to create the vault like solidity of the Emerald. The entire
cabinet is formed of an incredibly inert and well-damped medium density fiberboard (MDF) specified at 49.3
pounds per cubic foot density, with solid hardwood panels added over the MDF cabinet. Pick up an Emerald
and notice it weighs twice as much as other speakers of comparable size. This is one solid little jewel!

Both drive units were designed with effective resonance control in mind. The tweeter structure itself
is well damped and the bass-mid unit uses a rigid cast chassis.

We've attempted to show you some of the important design considerations that go into the Emerald system.
To fully document the design process would require many hundreds of pages. We haven't even discussed
the extremely high level of quality control that must be exercised in the drivers, crossovers and enclosure to
maintain the design standards. But the most important point is that the Emerald was designed by and for
music lovers. You must hear the Emerald system reproduce your favorite music and or video soundtracks
over a period of time to appreciate how fine these speakers are.

Using your speakers

If the rest of your system does not work properly or is not correctly connected you will not get the best
performance from your system. To eliminate problems we recommend the following:

I. Use the finest associated components you can afford. Turntables, cartridges, pre -amps,

amplifiers (receivers), CD and DVD players, and cables all have profound impact on the sound

of your system. Accurate speakers let more detail through. You will hear more of the beauty of

the music, but flaws in your system and or source material may be more obvious.

Any good audio system is made up of matched components. You wouldn’t use bargain recap

tires on a new Porsche, and you shouldn’t use inferior components with a high quality speaker.

Your Emeralds perform like speakers costing two to four times their price. Keep this in mind

when selecting the rest of your system.

Your Emeralds will work in systems with as little as 20 watts per channel. But for optimum sound

we recommend high-quality amplification of 30 - 150 watts or even more per channel.

II. Know your source material. People often blame their audio gear for poor recordings. A great

number of popular recordings are of inferior sound quality. Unfortunately this applies to records,

tapes, laser discs and CDs. Commonly poor recordings are rolled off in the low bass, and harsh

and constricted in the mids and highs. Good stereo image is rare. Many recordings are still

done on 40-year-old studio monitor speakers that are grossly inaccurate. Consider that some

producers still mix recordings to sound best on cheap table and car radios! This doesn’t mean

you can’t enjoy these recordings, but you should try a few of the best audiophile recordings just

to see how terrific your system can be when fed a good signal.

III. Work at getting the best placement of your speakers in their environment. It is not unusual to be

able to get a 25 to 50 percent improvement in sound by careful placement of speakers and

furniture. It may not be practical to go all out, but the more you can “tune” your room, the better

your system will sound. Refer to the section on placement and room treatment.

Specific applications including video and use with Subwoofers

The Emeralds were designed specifically for the highest quality video applications while also being suitable
for conventional audio only uses. The computer-designed reflex port extends the bass response beyond
what is found in sealed systems. However, when used with subwoofers this port should probably be
“stuffed” with 3” by 2” foam plugs. Push the plug into the port until approximately ½” is left outside the
cabinet rear. “Stuffing” the ports usually enables a smoother transition to the subwoofers but you should try
the speakers with and without stuffing to find the optimum sound for your system.

Avoiding Damage

Audio Concepts, Inc. speakers are designed for the purpose of accurate reproduction of music in the home.
We do our best to make our speakers rugged and reliable. However, ANY speaker or system may be
damaged under certain conditions:

• Excessive power, particularly at certain frequencies or for prolonged periods of time.

• Excessive distortion often caused by under-powered amplifiers or receivers.

• Defective amplification.

• Excessive subsonic energy.

Our systems are tested at high volume levels with a variety of amplifiers and receivers before a design is
approved. With many years of testing, we know it is virtually impossible to damage a component without the
system first giving audible warning in the form of distortion. We also know that true factory defects are
extremely rare, less than one in 10,000 drivers. Here are some considerations to keep in mind to avoid
damaging your drivers:

1. Even though a system may be rated for 100 watts or more it is very easy to damage it with a low
power receiver. When an amplifier runs out of power, it “clips”. This clipping produces large amounts
of distortion that sends excessive energy particularly to the midrange and tweeter. This clipping
distortion accounts for more than 80% of all tweeter failures. How do you know if the amplifier is
clipping? Volume knob placement does NOT indicate much. Some receivers reach full output well
before 12:00 on the dial. Use of the loudness button, bass boost and treble boost can all drive the
receiver and then the speaker into distortion at fairly low levels.

2. Many of today’s recordings including CDs and DVDs contain extremely powerful low bass. This low
bass can easily drive woofers into over-excursion or cause the amplifier to run out of power and clip,
causing tweeter or midrange damage.

3. Our systems are designed for accurate sound. Our rate of damage or failure is extremely low. We
could make the systems even more rugged if we were to compromise sound quality. Moving the
crossover points upward would protect midrange and tweeters better while causing a loss of detail,
clarity and imaging. The cabinets and woofers could be designed to roll-off the low bass which
would protect the woofers but this would lessen the low bass response and clarity. Protection
devices could be added in the crossovers, which would shut the system down when damaging
power or distortion was present but every one of these devices audibly degrades the sound!

7

You can protect your speakers by following a couple of very simple guidelines:

• If it sounds at all distorted, turn it down. Distortion is a warning sign that should not be ignored.

• Use tone controls or equalizers with caution. IF you must use equalizers, monitor the system

carefully.

• Beware the party damage epidemic. Speakers are more often damaged during parties. All those
bodies soak up sound, requiring more output to sound as loud, bass and treble controls are
sometimes cranked up and nobody is listening for distortion!

• Watch out for energy put out by the amplifier in the range below 20Hz, which is not music.
Examples include record warps, DC current and subsonic noise in the recording. These signals can
take up a lot of amplifier power which means the amplifier runs out of steam very early. These
signals can also overload a speaker even though you can’t hear them. If you have ever watched a
cone “flap” you know just what we mean.

• Vented speakers are particularly sensitive to signals below their F3 point. The average vented box
that can hand 100 watts at 50Hz may hand less than 5-10 watts below 25Hz! Sealed box speakers
with low Qts. numbers have a similar characteristic although not as severe. Low organ or
synthesizer notes may cause an otherwise excellent woofer to bottom out at relatively low input
levels.

• Keep an eye out for excessive cone movement that is not producing music. Find the source of the
problem and eliminate it, play at low levels, or use a subsonic filter (usually in your pre-amp) which
will filter out energy below 20Hz. However, use of a subsonic filter may take away from the
naturalness of bass sounds. We don’t recommend it for extremely critical listening.

• In over twenty five years of daily evaluation of all types of speakers on everything from ten to 1000
watts and with all kinds of music, we have never damaged a driver without first hearing audible
distortion. If it sounds bad, turn it down and you will never damage a speaker.

Hookup

Your speakers are furnished with five-way type binding posts. You may choose to utilize spade lugs, banana
jacks, pins, or bare wire. It is important that the positive and negative leads do not touch. If you use bare
leads, be sure to twist them tightly and insert through holes in such a manner that they do not fray or short
out against each other. Good connections are important, so make sure any ends are tightly crimped and
preferably soldered to the wire ends. Speaker wires should be kept as short as possible, (long wires add
excessive resistance and color the sound.) The use of quality wire is recommended. Audio Concepts, Inc.
stocks and recommends T-14 speaker wire by DH-Labs. Make sure you hookup the speakers in the correct
polarity. The red (positive) terminal on your amp should hook up to the red binding post, and the black
(negative) terminal should be connected to the black binding post. Keep this the same for both speakers in a
stereo pair, and all three front speakers in a home-theater setup. A way to check the correct polarity is to
play music with a lot of bass. The correct hookup will yield the greatest amount of bass.

Positioning your Emeralds

• If the speaker will be at or below seated ear level the woofer should be at the top of the enclosure.

• If the speaker will be above seated ear level the woofer should be at the bottom of the enclosure.

• For the very best Dolby Surround imaging the three front speakers should be at approximately the

same height.

• However: Because of the unique radiation pattern of the Emerald, it is possible to approximate
equal height by having Emeralds that are placed below ear level with the woofer on top, and
Emeralds placed above ear level with the woofer at the bottom.

Placing the speakers in your room

As mentioned, the proper placement of speakers in your room will easily improve the sound. Because all of
our rooms and tastes are different, it is impossible to specify a “correct” placement. Instead, let us present
you with some acoustical facts, then you can optimize placement in your room.

It helps to visualize sound waves as behaving very much like water waves. The sound we hear is made up
of two types of waves. Direct sound waves come right from the speaker and are not changed in any way.
Reflected waves come to us after bouncing (diffracting) off the speaker enclosure itself, or walls, ceiling,
floor or furniture. If you want to see how much these reflected waves affect the sound, move your speakers
outside and hear the difference.

Sound waves come in different lengths ; the lower the note, the longer the wave. Extreme low frequencies
such as the lowest organ pedal notes are over 60 feet long! If your room is not big enough, the wave can’t
develop fully. But the biggest problem with bass notes is the phenomenon we call standing waves. In effect
the waves more or less “pile up”. This creates big peaks and dips in the bass response. If you put a certain
frequency through the speakers, you can usually walk around the room and find places where it is very loud,
and places where you perceive virtually nothing.

Just as the room affects the bass response, so it affects the mid-treble sound of the system. In the mid­treble range, the sound waves are shorter and have peaks and dips, most of the affects (peaks and dips)
occur from enclosure edges, furniture, walls, or the floor. Emeralds exhibit the deepest image when placed
away from walls and furniture. The shorter wavelengths of the mids and highs are more easily absorbed
than the longer wavelengths of low frequencies. This is why a bare room sounds so harsh compared to a
room with a lot of stuffed furniture, carpets, drapes, etc.

An ideal setup for sound would be achieved if you could:

• Choose a room with width, height and length dimensions that are not multiples of each other. (A
cube would be the worst!) Good numbers might be something like, height = 8 feet, width = 15 feet,
and length = 26 feet.

• Choose a room that has an irregular shape, non-parallel walls cut down on standing waves.

• Place the speakers so that the woofer cones are at irregular distances to the floor, walls and ceiling.

This can be difficult. Use a tape to measure the distance from the center of the woofer to the room
boundaries. Move the woofers around till you have cut down on the number of related distances.
(You don’t want distances like 12 and 24”, but more like 12 and 22”). Use the distance from the
woofer to the boundaries to increase or decrease bass output. Sticking the speaker in the corner or
close to walls will give more bass output than putting the speaker out into the room. You can use
this to get the best balance between bass output and upper range output.

• Use absorbent materials to help smooth upper-range response and improve transient response and
clarity. Why? let’s take the sound of a bell for example. First you will hear the direct sound from the
speaker. But some of that sound bounces from wall-to-wall, ceiling-to-floor, off furniture, etc. before
it reaches your ears milliseconds later. Because the time difference is short, you don’t hear an echo,
but the sound of the bell is stretched out from something like a “ding” to a “ddiiinngg”. Some
speaker engineers have begun to realize this and are addressing the problem in their latest designs.
This is why we are now seeing very directional designs. This controlled directionality increases the
amount of direct sound in proportion to reflected sound.

• Place speakers as far as possible from other furniture and room boundaries. Keeping the mids and
tweeters away from the floor is particularly important. For stereo use, the Emeralds are designed to
sound best when the optional Atlantis or Sanus stands are used. These stands can be sand filled
and are highly recommended. For center channel video use, the Emerald will ideally be positioned
directly under or above the video screen. If the Emerald(s) are under the screen or stand mounted
the woofer should be at the TOP of the cabinet. If the Emerald (s) is mounted above listening height
the woofer should be at the bottom of the cabinet.

9

• Use padded furniture and drapery when possible to cut down on reflections. Furniture has the
added bonus of helping to break up standing wave patterns in the bass.

• Use a symmetrical placement of the speakers in the room. Of course the distance between the
speakers is also important. In general, the further back your listening position, the farther apart
should be your speakers.

• In most rooms, you will want the Emeralds placed between five and eight feet apart. Experiment!
Too much distance will smear the image and it will seem like there is a hole in the middle. Too
small a distance will compress the image. Experiment with facing the speakers straight into the
room or toed in slightly toward the listener. For video applications the left and right speakers should
be close to the edges of the screen.

Speaker Break-in ****Important!!!

Allow at least 60 to 80 hours of playing time before your new ACI speakers will sound their best. The
adhesives and materials used in manufacturing must stretch and flex properly before a speaker will sound
its best. After break-in the bass will be tighter and go lower, imaging and transparency will improve and the
midrange and highs will sound smoother and more natural.

Suggestions for quicker break-in:

• Play the Emeralds at medium volume while away from home. A CD player on repeat or FM radio
works fine.

• Place a pair of Emeralds grill-to-grill and reverse the polarity on ONE of the speakers. Wiring them
out-of-phase like this will cancel much of the sound and allow you to break them in when the sound
would otherwise be obtrusive.

Troubleshooting

Occasionally we get a call or email from someone who feels there is a problem with their ACI

speaker. At least a couple of times a year we will get a call or email that goes something like this: “Speaker
not working properly, can’t get enough sound even with the volume turned way up.” The problem may be
different, but with this little information to go on it is almost impossible to trouble shoot the problem “long
distance”.

The following checklist may help:

1) Are all system hookups properly connected, not partial shorted wires, or reversed connections,

etc?

2) Did you try the rest of your system with other speakers to determine if the problem exists with

the speakers?

3) Please be realistic in your expectations. Our speakers offer excellent value but we can’t beat the

laws of physics. For instance, a medium sized speaker such as the Sapphire sounds excellent
but will not play as loudly as a very large speaker.

IF for any reason you aren’t satisfied with the sound you’re getting from your speakers we want to know
about it. Make sure the speakers have had adequate break-in time. Before you call, write or email, please
try to narrow down the problem and eliminate other factors. If you contact us we will need to know:

• The size of your room

• Where you have the speakers placed

• What other equipment is in your system

• Have you tried other speakers (which ones, and did they eliminate the problem)

• Any other specific symptoms or information you can provide
