The Essence of Music is Emotion
The mission of a great loudspeaker is to recreate the musical event so
vividly and so accurately that the listener at home experiences the same emotion
evoked by a live musical event.
Audiophiles and audio manufacturers talk endlessly about such benchmarks
as imaging and soundstage, separation and definition.
EgglestonWorks
loudspeakers of course excel in those areas, but they are really secondary issues,
derived from the ability to precisely capture the basic elements of music: timbre
intensity and pitch. To build a loudspeaker that does full justice to those basic
elements requires not only a lifetime immersion in the experience of live music,
but also a thorough knowledge of the process that produces the records and CDs
we listen to at home. The design approach at EgglestonWorks exemplifies that
knowledge and experience.
At EgglestonWorks, the skill and craftsmanship gained in years of speaker
building combine with a deep understanding of what went into the recording. The
goal, always, is to produce that emotional response that makes music meaningful.
Responding to music is instinctive. When listening to a loudspeaker that is
honestly recreating a musical event, you don’t have to analyze why it sounds right
– you know it instinctively.
As a new owner of an EgglestonWorks loudspeaker system, you join a
discerning group of serious music lovers who have set the highest standards for
musical reproduction. We, at EgglestonWorks, are committed to creating a
musical experience that exceeds that standard both visually and sonically.
Before You Unpack
If you are reading this, then you have successfully opened your boxes. It is
important to follow these instructions closely, to avoid damaging the speaker or
injuring yourself.
It is very important that you first carefully inspect all shipping cartons for
damage. EgglestonWorks loudspeakers are packed extremely well, and any
damage encountered during shipping should be limited to the packaging. When
purchasing through a dealer who is also doing your set-up, damage to the speakers
is not usually a problem. However, if a shipping company is involved in the
delivery of the speakers to your house, there is always the potential for damage to
occur. It is very important to contact your dealer or the shipping company
immediately. Damage claims must be filed with most shipping companies within a
few days of delivery.
EgglestonWorks recommends that you save all packing materials. The
speakers are very heavy and due to their unique design, these cartons are the safest
way to transport them if needed.
Unpacking Instructions
1) Remove the top pieces of foam packing material. The spikes are taped into
one of these pieces , so find them and set them aside for now. The front
baffle of the loudspeaker should now be exposed. It is extremely important
not to touch the tweeter dome located at the top of the speaker.
2) There are two small pieces of foam at the top and bottom of the speaker;
these will also need to be removed. They fit very snug so pull them firmly.
3) With assistance, tilt the carton from one end so that the speaker will be
standing up right. [The speaker will want to fall forward, so you must hold
on to it.]
4) When the box is upright, allow the speaker to tilt forward so that its front
feet rest on the cardboard.
5) Slowly walk the speaker out of the box and to its final destination. To
protect against scratches, we recommend leaving the cellophane covering on
until you are finished moving the speaker into place.
Save the box and all packing materials.
Connecting the Loudspeakers
Consult with your authorized EgglestonWorks dealer for recommendations on cables and
connectors for your loudspeakers. Cable and connector quality greatly affects the sound of your
loudspeakers. In general follow these guidelines:
! Do not use bare wire connections. EgglestonWorks recommends only
spade or banana plug connectors.
! Keep the cable runs as short as possible.
! Keep the cable resistance (impedance) as low as possible.
! Use only the highest quality cable
! Use non-ferrous, non-oxidizing connectors. Gold plating is
recommended.
! Allow for maximum amount of contact area.
! Tighten, but DO NOT OVERTIGHTEN, all connections.
! Periodically clean and reattach all connections.
! Make sure polarity is kept consistent when connecting your
loudspeakers. Always connect the positive terminal of your amplifier to
the positive terminal of your loudspeaker, and negative to negative.
Cable companies generally indicate the positive and negative
connectors at each end of the cable. The most common practice
includes a red marking for positive, and black or no marking for
negative. EgglestonWorks speakers are set up with positive on the right
and negative on the left when facing the rear of the speaker.
Reversing the polarity will result in a collapse of the soundstage, a nonexistent image and a cancellation of bass frequencies, so be careful.
BI– Amplification / BI Wiring
Due to the unique crossover configuration of our loudspeakers, advantages of biamping and bi-wiring are maximized. We supply the Andra III with two sets of binding posts to
allow for bi-wiring or bi-amping.
The top set of binding posts drive the tweeter and midrange, and the bottom binding posts
drive the woofer section.

Initial Set-Up
EgglestonWorks loudspeakers are recognized as the most resolute, detailed, and
musically accurate speakers available in the world today. As such, they are more sensitive to
their positioning both within the room and relative to the listener. Moving the speakers in what
may seem like small increments can result in great differences in sound. The key to finding the
best position in your listening room will be experimentation, but these guidelines, combined with
your dealer‘s advice, should produce optimal sound.
•
Due to the unique design of EgglestonWorks loudspeakers, they are typically placed
much closer to the walls of your room than most speaker systems.
•
In general, we suggest starting with the speakers 24” from the rear wall.
•
We also suggest a center to center measurement of 8feet to start.
•
The distance from the rear wall and the side walls should be unequal.
•
The distance between the speakers will depend on the particular listening room, but a
wider stance than most systems is sometimes needed. The minimum distance between
the speakers should be 7.5 feet (center to center).
•
The distance to the listening position can most often conform to the theoretical idea of an
equilateral triangle with the speakers and listener as the three points. In some situations,
the listening position can be slightly farther back. (example. 8 feet center to center and
10 feet to listener.)
•
The speakers should be toed-in slightly, but not necessarily aimed directly at the listening
position. Experimentation here is key.
The toe-in is a key element in the performance of the speakers. In general, if the speaker
is toed-in and aimed directly at the listening position, the best imaging will be heard, but the
soundstage will not be as wide as possible. Toeing the speakers out slightly will result in a wider
soundstage, and usually more realistic imaging. Depending on the spacing of the speakers, a toein of somewhere between 15 degrees and 30 degrees is suggested.
When setting up your new speakers, the most important thing to remember is that
experimenting with placement is the only way to find the right place. Because all rooms are
different in size, materials, and furniture there is no way to give clear cut instructions on
placement. Additionally, because electronic equipment and musical tastes also greatly affect
placement, you will be the best judge of the sound.
Amplification
The EgglestonWorks Andra III is a relatively easy speaker to drive. With an efficiency
of 89 dB, the load presented to an amplifier is quite stable. Nominal impedance is 8 Ohms, but
rarely drops below 5.6 ohms. Because of this impedance curve, we typically recommend
amplification minimum of 80 watts per channel. Because not all amplifiers are created equal, this
minimum can change depending on a certain amplifier and the quality of the current it is capable
of delivering. We recommend careful audition at your dealer to determine if a particular
amplifier will make a good match with the speaker. Use low-powered, single-ended triode
amplifiers only after consulting with your dealer or after audition.
Speaker Supports
Your EgglestonWorks loudspeakers were supplied with custom spikes that screw into
the steel feet on the bottom of the speaker. We highly recommend using these spikes as they
help dissipate cabinet energy, resulting in tighter bass, better focused imaging, and more accurate
soundstaging. If you have a non-carpeted floor, EgglestonWorks manufactures spike “coasters”
to be placed between your floor and the spike point. These are available from several
manufacturers and your dealer can help you locate them.
Care and Maintenance
The glossy surfaces of your speakers can be cleaned using a soft, 100% cotton cloth.
Never use paper towels, abrasive pads or abrasive cleaners. A non-ammoniated spray glass
cleaner may be used. Several companies make polish especially for plastic (you will have to
look for particular brands in your area).
Wax can also be used on the acrylic to bring back their shine and fill in small scratches.
This can be found at most automotive parts and accessory stores. We recommend either dark
blue or black.
Speaker Break-In
Your EgglestonWorks loudspeakers use the finest drivers available in the world today.
The internal components of these drivers are very stiff when they are new, and require quite a bit
of use before they fully loosen up. EgglestonWorks practices moderate in-house break in of your
speakers, typically not exceeding 50 hours. This partial break in is to reduce the time it will take
at home to loosen the drivers sufficiently. We recommend that your speakers play at moderate to
high levels for at least an additional 100 hours before they are fully broken in and performing at
their peak.
Warnings
The EgglestonWorks Andra III loudspeaker system was designed with
unequaled standards in construction integrity and parts quality. The drivers can
endure extreme conditions, and all crossover components are designed to withstand
high power envelops. The speakes are not indestructible, however. Following a
few simple guidelines will help to protect your investment and insure proper
performance.
! Never connect any loudspeaker directly to an AC power line. Severe
damage to the speaker will result, in addition to the possible risk of electric
shock.
! Avoid over-driving the amplifier or speaker. EgglestonWorks loudspeakers
are relatively easy to drive, but they demand amplifiers capable of delivering
a large amount of current. Over-driving the amplifier or speakers can
produce:
! Distortion, static, compression or other unnatural sounds.
! Clicking & popping sounds from the amplifier.
! Very harsh sounds from the woofer(s), resulting from “bottoming
out”.
! Use care whenever moving the speaker. “Walking” the speaker is
acceptable only with the spikes removed. If the spikes are installed,
“walking” will damage both the spike and the spike receptacle.
! NEVER TOUCH THE TWEETER DOME. We recommend leaving the
tweeter guard in place at all times. We also recommend that you never
touch the midrange and bass drivers except with a soft cloth for periodic
cleaning.
! Avoid prolonged exposure to direct sunlight. It can damage the finish over
time.
! Avoid extreme humidity. High humidity can affect the cabinet, adhesives
and electrical contacts.
! EgglestonWorks loudspeakers are extremely heavy. Never attempt to move
them without using extreme caution and/or someone’s assistance.
