Foreword
Thank you for your purchase of an Eden D Series loudspeaker
enclosure. This cabinet has been designed and constructed to give you years
of trouble-free service. Please take the time to review this manual and to
send in your warranty registration card.
We are proud that we are the only bass amplifier manufacturer to design,
engineer and manufacture its own speakers and hi-frequency devices, all in
our own facility. This not only gives us much greater quality control, we can
also make exactly what we need for any given design. We design and
engineer all of the individual loudspeakers and all of the enclosures to work
well with each other so that the synergy of the overall design is greater than
the sum of the parts.
We have used only AA void-free plywood in the construction of your
enclosure. Other manufacturers may use C or D grade, which allows for
voids and patches that can degrade over time, causing rattles, or fall apart
completely. Your cabinet has been constructed using the finest
craftsmanship. We use a special glue and use Dado and Rabbet interlocking
joins to ensure you a lifetime of use. Your enclosure features massive
internal bracing and has been computer designed and hand-tuned to perfectly
match with our hand-built speakers and high-frequency drivers to ensure
maximum transient response and best overall sound.
Please read this manual in its entirety before operating your new speaker
system. Failure to do so could result in misuse or damage. We’ve taken the
time to write it, which was a lot longer than the time it will take for you to
read it. Help us help you by taking a few moments to learn how to properly
use your new cabinet. You’ll be glad you did!

CAUTION!
Your ears are your most important piece of
equipment. Unfortunately, they cannot be replaced
as easily as your other gear. Please take the
following warning seriously.
This product, when used in combination with
amplification and/or additional loudspeakers may
be capable of producing sound levels that could
cause permanent hearing loss. DO NOT operate at
high volume levels or at a level that is
uncomfortable. If you experience any discomfort or
ringing in the ears or suspect hearing loss, you
should consult an audiologist.
Thank you for your purchase of an Eden bass

OPERATING INSTRUCTIONS
As previously mentioned, Eden is the only bass amplifier manufacturer to
design, engineer and build its own drivers. Designing and building our own
speakers and high-frequency drivers allows us an opportunity to create far
greater synergy between our drivers and cabinets than any other
manufacturer can achieve. We can create several speaker and/or cabinet
prototypes and then test them together to find the best possible combination.
No other manufacturer has this capability, which is why no other
manufacturer can equal Eden’s sound and reliability.
Eden loudspeakers feature a cast frame (except for the EC1560ES in our D215XL(T) cabinet) and edge-wound voice coils. Our horn-loaded, cast
aluminum bullet tweeter is the standard in the industry. We use a 6/18db
crossover with level control, as well as a finely calibrated limiter for
protection in high-volume situations.
TYPES OF ENCLOSURES
We manufacture a broad array of enclosures to ensure the every bassist on
the planet can find the perfect cabinets to match his or her playing style and
personal tonal requirements. Our enclosures are grouped into the product
lines outlined below. Each product group has its own tonal characteristics.
For complete specifications on your particular cabinet, refer to Appendix A
at the end of this manual.

XLT SERIES
This is our best-selling line of speakers, with numerous models from which
to choose. The XLT series cabinets have a low-mid bump that gives them
their authoritative growl. This helps the bass cut through even the muddiest
mix. Our D410XLT is the touring standard around the world. Product
offerings in this group include:

XL SERIES
For those desiring a cabinet with less highs and more of an old-school or
traditional tone, we offer the XL series. These are the same as our XLTs
except they have no high-frequency driver. Available in single or dual 15,
and single 18 configurations, these cabinets are an excellent choice for
bassists desiring a cabinet steeped in the tradition of 60s and early 70s.
XST SERIES
Our newest line of enclosures, the XST series features a deeper bottom end
that is tighter and more focused, combined with a smoother midrange. These
cabinets were designed with the hi-fi, hi-tech player in mind. They are also
excellent for Pedal and Synth bass, as well as keyboards. Currently there are
two models in the XST line:
610XL

BASIC CONNECTIONS AND OPERATION
There are three speaker connections on the connection panel: two standard _
inch jacks and one NL4 connector. These connections are all wired together
in parallel. This means that any of the connections can accept the input from
your amplifier and that the remaining two connections can be used to
connect to additional speaker cabinets if desired.
NEVER CONNECT TWO AMPLIFIERS TO ONE CABINET!
Let us repeat this: NEVER connect two amplifiers, or two channels of the
SAME amplifier, to one cabinet. This is a Very Bad Thing which will
damage your amplifiers and possibly the enclosure. It may also result in an
impressive pyrotechnical display – once.
You should make all your connections before turning your amplifier on.
Standard _ inch plugs are less than ideal in their ability to transfer the signal
from your amplifier. This is due to the limited amount of actual contact area
in these connections. For best performance, we recommend using NL4 style
speaker connectors. We also recommend using high quality speaker cables
of at least 16 gauge min. (smaller numbers indicate larger cable).
IMPROTANT NOTE: Using a shielded instrument cable to connect your
amplifier and speakers is a Very Bad Thing. DO NOT use shielded
instrument cable for speaker connections unless you want to cause serious
damage to your amplifier.
TWEETER LEVEL CONTROL
The Tweeter Level control is located on the connection panel on the back of
your cabinet. In general we recommend you initially set the control to its
12:00 (or flat) position. Users who aren’t used to having a tweeter in their
bass enclosure may want to turn the tweeter down to the point that it is
barely operating and, over time, slowly adding more tweeter into the mix.
The rear (inside) of the connection panel also houses the crossover and
tweeter protection system. This system uses an aircraft-grade light bulb in a
circuit that is designed to absorb current that is in excess of the powerhandling ability of the tweeter.
6
In cases of very high levels of high frequency information (such as feedback
from facing the cabinet with your instrument turned up), the bulb can glow
brightly enough to illuminate the interior of the cabinet and shine through
the speaker surrounds. While this is a rather dramatic display of the
protection circuit, it should not be done intentionally. It’s much better to find
another way to impress your drummer!
Excessive amounts of current will cause the bulb to act like a fuse and fail,
requiring replacement before the tweeter will function. Replacement bulbs
are available from our factory. In an emergency, an automobile dome light
bulb can be used to restore the system. To replace the bulb, simply remove
the screws that secure the connection plate to the back of the cabinet. Gently
pull the plate out and replace the bulb in its connection clips.
BREAK-IN PERIOD
We recommend that you use your D Series cabinet at low to moderate
volume levels for approximately ten hours before using it in a high volume
situation. This will allow the suspension components to “seat” themselves
and the speaker to break in. This is very similar in concept to breaking in the
engine of a new car. It will actually take about 24 to 50 hours of total
playing time to fully break in your speaker system. If desired, you can plug a
CD player into your amplifier and play a CD through your enclosure to
accomplish this break-in.
CONNECTIONS WITH ADDITIONAL CABINETS
It is important to keep two issues in mind when connecting your David
Series cabinet with other cabinets: phase relationships and impedance.
Proper parallel connections require the positive and negative speaker
terminals to maintain their relationships throughout the system. This means
that the positive connection (tip on _ in. plugs; the red binding post) on one
cabinet must connect to the positive connection on additional cabinets. The
negative connections should be made in a similar manner. Unless you have
defective cables, _ in. connections make incorrect connections highly
unlikely. If you are using NL4 plugs to connect there should also be not
problem with phase relationships. If you wish to connect multiple cabinets in
SERIES, you will need to use special single wire cables with individual
banana plugs, attaching them to the cabinets as shown below. (You can
purchase _-banana adapters for this purpose, if necessary.)

Impedance is a measure of the load your speaker system places on your
amplifier. Too great a load (indicated by a lower impedance figure) can
damage your amplifier. Too small a load (indicated by a higher impedance
figure) can fail to draw adequate power from your amplifier. Please consult
your amplifier manufacturer’s literature for impedance recommendations.
We hope this means you’ll be consulting another one of our manuals, by the
way. If this is not the case, may we humbly suggest you trade up to a better
amplifier?
When you connect speakers in parallel, the load increases as shown below:

As you can see, problems tend to arise when using more than two cabinets.

POWER HANDLING
Your speaker system can be damaged by too much or too little amplifier
power. While the amount of amplifier power reflects the potential for
damage, how that power is used (your playing style) is the critical variable.
Too small an amplifier, when pushed to its limit too often, can generate
excessive clipping. This can generate a signal with enough extra high
frequency distortion to eventfully overheat and burn up a voice coil. Too
large an amplifier, when pushed near its limit, can push the speaker beyond
its physical limits. Your playing style determines how much headroom
(reserve amplifier power needed to handle short bursts of sound) you will
need. Slap style playing is particularly demanding, as short bursts of low
frequency information require a great deal of power to be produced
accurately without distortion. You should choose an amplifier that delivers
adequate power for your playing style without frequent clipping and without
exceeding the cabinet’s power handling maximum during normal usage. It is
OK to have extra power for added headroom. Just be careful to use it for that
purpose.
Also, keep in mind that simply adding amplifier power will not necessarily
increase your volume significantly. The addition of more speakers will
usually have more impact on your overall volume level and improve your
overall presence and tone.
CABINET PLACEMENT
The placement of your cabinet can also have an impact on the amount of
bass it produces. Placing the unit on the floor increases the amount of Bass
you get by an additional +3dB . With each additional wall surface placement
you get another 3 dB increase. This is due to the reinforcement of bass
frequencies by the adjacent surfaces.
9
The absence of reinforcing surfaces is the reason why outside settings are so
problematic for bass amplification. A system that may be perfectly adequate
in a fairly large club can be rather disappointing on an outdoor stage. If you
have plans to perform in such a setting and are not confident that the P.A.
system can provide you with sufficient reinforcement (both out front and via
monitors), you should consider using additional equipment to support your
own sound.
MAINTENANCE
Your speaker system is designed to be trouble-free and to require very little
maintenance. You should remember that the weakest links in most systems
are the solderless connection points where your plugs and jacks come
together. These connections are quite vulnerable to contamination and /or
corrosion, which can lead to Wimpy Bass Tone. And if you wanted that,
you wouldn’t have bought an Eden speaker system, now would you?
Your input jacks, as well as your speaker cable plugs, should be periodically
cleaned using a cotton swab with a solvent such as denatured alcohol. On
cabinets equipped with casters, you should check to make sure that the
screws the hold the caster sockets in place are tight.
IMPORTANT NOTE: Speakers are not waterproof. The cones themselves
are made of special high-strength paper. If your speakers get wet, make sure
they dry out completely before using them again. If you do not, you may
cause mechanical damage to the speaker, and this is a Very Bad Thing.
You can keep the carpet covering on your enclosure clean by using a Lint
Roller (the masking tape style). If you need to remove ground-in dirt, use a
commercially available carpet cleaner. Make sure, however, to protect the
connection panel and speaker grill during cleaning.
To remove the odor of airborne contaminants (smoke, e.g.) or the beer your
drummer spilled on your cabinet during the last gig, use a commercially
available fabric freshening spray.
10
CLIMATE AND TRANSPORTATION
Routine temperature extremes (such as cold garages) will not harm your
Eden cabinet. You should, however, allow the system to adjust to room
temperature before playing it at loud volumes. If your cabinet is going to be
bounced around severely during transportation, it is best to avoid loading it
with the speaker cones facing down, as this puts added stress on the screws
that secure the speakers in the cabinet.
THE MAGIC SMOKE
Few people realize just how much magic goes into creating Great Bass
Tone. It isn’t something you normally need worry about. Just have fun and
leave all that to us. However – and this is very important – if you ever
release the Magic Smoke from your speaker, this is indeed a Very Bad
Thing, perhaps the worst thing you can do. If you see any smoke (Magic or
otherwise) coming out of your cabinet, immediately turn it off and seek the
services of a qualified magician…uhm, we mean…technician. DO NOT
continue to use the speaker system in this condition.
