IMPORTANT NOTICE

All new speakers require a minimum of 60 hours break-in-time before they begin to
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:

3

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 Maestro XL is very heavy. We strongly recommend having two

people available to remove from packaging.

The Maestro XL Powered Subwoofer

Thank you for your order and congratulations on becoming the owner of an ACI speaker system. The
Maestro XL powered subwoofer(s) will provide you with many years of listening pleasure!

ACI’s Maestro XL is an extremely powerful subwoofer. Although relatively large, a conventional
subwoofer of equal performance would have to be twice the size! The Maestro XL is based on the subwoofer
technology of our legendary Titan series. An extreme excursion 15" driver is powered by our proprietary
amplification using special circuitry to essentially cut the required box volume in half.

Many subwoofers do a respectable job with explosions, shotguns, and crashes. The market is loaded with
black boxes and tubes that beg to be "hidden". The Maestro XL is different . Reasonably sized and attractively
built to compliment your fine furniture. A number of fine wood finish choices are available. The Maestro XL goes
way loud, and it goes way deep. Warning: ACI is not responsible for any tickets you may receive for noise
violations or domestic disturbance! More importantly, it will allow a seamless and completely transparent blend
with your main speakers. Your sound stage will be enhanced, not degraded. Instruments like acoustic and electric
bass, piano, and percussion will come through with vivid realism. The Titan and Force have earned a reputation
of being some of the most musical subs available at any price. The Maestro XL continues this tradition of musical
excellence in an extreme output configuration.

The internal enclosure is constructed of 1” non-resonant high-density fiberboard with extensive internal
bracing. The mounting for the down-firing woofer is 2" thick for additional resonance control and stability. Satin
black durable finish, cherry veneer, or piano gloss black available.

4

Many subwoofers add unacceptable colorations and actually degrade the performance of otherwise fine
speakers. The Maestro XL is adaptable for use with virtually any satellite, electrostatic or ribbon speaker. If you
are satisfied with your present speakers but just want more bass power and extension, the Maestro XL(s) may be
the perfect answer. If you own speakers from manufacturers such as B&W, KEF, Aerial, Quad, Thiel,
Magnaplaner, Revel, Thiel, Martin Logan, Wilson, etc., you’ll find your listening pleasure greatly enhanced with
the Maestro XL subwoofers.

Maestro XL Subwoofer Setup

Integrating a sub is a process that requires following ordered steps. You’ll find it easy in some
rooms/systems, and very time consuming in others. The key is to eliminate each variable one at a time. We
include a setup disc, free with purchase of our subs. Use of the setup CD is optional. Please refer to the attached
directions for the test CD.

5

The front panel controls of the Maestro XL perform the following functions:

Faceplate: The Maestro XL amplifier is shipped with a cosmetic faceplate installed. This faceplate needs to be

removed to make the setup adjustments. An allen wrench is supplied to remove the four bolts that hold the
faceplate in place. Once setup is completed you may re-install the faceplate for a finished appearance and to
keep un-authorized fingers from upsetting your adjustments. The amplifier is also supplied with brackets and
hardware for optional installation into standard 19” racks.

Run / Standby Switch: This push button switch is used to toggle the amps operating mode between Run and
Standby. The Standby mode mutes the outputs and the amp is in idle and virtually no current is drawing from the
AC lines .

Run / Standby Indicator LED: When the BLUE LED on the front panel in ON it indicates the amp is in Run
mode. When the BLUE LED is OFF and the Protect LED is YELLOW, it indicates the amp is in Standby (Mute)
mode.

Power-on / Fault Indicator LED: The GREEN LED indicates normal operation. RED indicates an over­temperature or fault condition. In the event of RED LED at startup, turn the amp off, unplug the AC cord and
check the output, cable, and speaker itself for a short-circuit condition. In the event of a RED LED during normal
operation, switch the amp to Standby for a few minutes and wait for the GREEN LED to come on, indicating the
amp has cooled off and is ready to resume normal operation.

Level: This controls the volume of the Maestro XL. The volume needs to be set at the same volume as your main
speakers to get a seamless blend.

Lowpass / Crossover Control: Adjusts the frequency response of the Maestro XL. A 24dB/oct Linkwitz-Riley
filter is adjustable from 35Hz to 250Hz.

Phase / Crossover Switch: A four position switch used to change output phase from 0 deg to 180 deg and to
enable or bypass the crossover function.

• Position 1: 0 deg phase shift, lowpass crossover enabled

• Position 2: 0 deg phase shift, lowpass crossover bypassed

• Position 3: 180 deg phase shift, lowpass crossover enabled

• Position 4: 180 deg phase shift, lowpass crossover bypassed

The rear panel connections and controls of the Maestro XL perform the following functions:

Female adapters.

On/Off Switch: Used to turn the amp on and off. Normally amp is left on all the time. When not playing, it draws
about the same amount of power as a nightlight.

Power Cord: The cord is detachable and can be plugged into any standard 3 prong outlet.
Left & Right Line Level Inputs: These inputs accept line-level signals from an external source. Use either or

both of these inputs. They are internally mixed together by the amplifier’s input circuitry and applied to the
lowpass filter, level, and phase.

Sub Line Level Input: The primary purpose of this input is to simplify running multiple Maestro XL amps together
in a daisy chain hookup. The signal is buffered and passed directly to the sub output jack without any processing,
then to the input circuitry and applied to the lowpass filter, level, and phase.

Sub Line Level Output: Use to directly connect (daisy chain) multiple Maestro XL amps without loss of signal
level. This signal is a buffered output of the summed Left, Right and Sub inputs. The full-range signals from the
line level inputs are presented at this output, no signal conditioning, or filtering is done to this signal. The level,
crossover, and phase control have no effect on the gain of this output.

Speaker Level Outputs: (see diagram below) The speaker level amp outputs are for connecting to the Maestro
XL subwoofer enclosure inputs with a single length of speaker cable. Mount the amplifier near your source
components for easy access to the front panel adjustments.

6

Miscellaneous:

• Sophisticated circuitry protects the driver from being overdriven and reduces distortion.

• The ICE amplifier modules deliver over 500watts RMS to the woofer with extremely low distortion.

• Bulletproof design for high output levels without worry.

• A temperature switch monitors the output devices. In the event of excess heat the switch will shut down the

circuitry to prevent damage. Once cooled the power will be restored.

• The Maestro XL offers incredible performance in a relatively small cabinet because the electronics have been

designed and ”tuned” to the woofer and cabinet.

Speakers Level Adapter

Two of these are supplied with each Maestro XL subwoofer. The Speaker

Level Adapter converts an amplified, (speaker level), signal to the line level signal required by the
subwoofer. Not required for line-level hookup. The adapters may be installed directly in parallel with your
main speakers. This can be done at the speaker outputs on your receiver or amplifier. Alternately you may
put these in parallel with your speaker at your speakers input terminals. You may attach any type of
speaker cables to the speaker cable end using either electricians twist nuts or a twisted, soldered and
wrapped connection. If running shielded interconnects to sub, you will need to purchase RCA Female -

Y-Adapter

Used to split a line level output into dual outputs. Use with shielded RCA interconnects. For

example; use Y-Adapters at pre-amp outputs to get dual outputs. One set of outputs goes to the subwoofer(s),
one set of outputs goes to the main amplifier inputs.

RCA Female-Female Adapter

Used to join two shielded RCA interconnects. May also be used to join the ACI Speaker Level Adapter to any
RCA shielded interconnect.

Step One: Initial Placement

Determine initial placement of the sub. This is often a matter of "where it will fit" in the room. You will also need to
plug the Maestro XL amp into a 120-volt wall receptacle. The Maestro XL is supplied with a power cord. If this is
not long enough, you may replace or use a suitable extension cord. Three of the best places to put your Maestro
XL:

7

1. Place the sub in one of the corners behind the main speakers. A corner placement behind the main
speakers usually yields the deepest, cleanest bass. As long as the subwoofer is correctly adjusted it will
not be boomy or overbearing. The sub doesn’t have to be placed “tightly” in the corner, just as near as
possible.

2. Place the sub near the wall, behind the main speakers. Approximately 1/3 of the width of the room is
often ideal.

3. Place the sub along one of the sidewalls. Approximately 1/3 of the length of the room is often ideal.

If you have the flexibility to try different placements, we’d encourage you to do so. Every room is different.
Experimentation is the best way to find the best placement. One trick is to place your subwoofer in your normal
listening position. Listen or take measurements from your subwoofer placement options to find the ideal position.
For example, if your two options are the left front corner and somewhere along the right sidewall, you’ll listen and
or take measurements at these two positions.

Step Two: Hookup and Adjustment

The Maestro XL subwoofer may be integrated into virtually any quality audio or audio-video system. First you
must determine your hookup scheme. Select from the choices below and then make adjustments.

There are essentially two types of hookup and adjustment:

1. Home Theater ( 5.1 - 7.1 systems ) Systems with a subwoofer output on your receiver or processor

OR

2. Stereo (two-channel) Systems without subwoofer output

Home Theater - Hookup

This approach requires a shielded RCA interconnect cable from the subwoofer output on your receiver or
processor to one of the inputs on your Maestro XL amplifier.

• Choose either the Left or Right input. You will be setting the crossover to bypass and using the bass

management of your receiver or processor. There are currently many different bass-management
schemes depending on brand and model of receiver, pre-amp or processor. You will most likely set
all your main speakers to "small" although it is a good idea to experiment with these settings. Your
receiver, pre-amp or processor controls subwoofer volume after initially being set on the amp.

• The sub input can also be used and is available to aid in daisy chaining multiple subs. If you wish to

use multiple subs for higher output levels simply daisy chain the sub amplifiers together using the
subwoofer outputs on the Maestro XL amp.

Home Theater - Adjustments

Adjusting the Maestro XL for Home Theater:

1. Lowpass crossover frequency doesn’t matter, it will be bypassed and controlled by your processor.

2. Set phase to Bypass and 0 degree. Then use the test CD to determine whether phase should be at 0 or
180 degrees. (Please refer to the test CD procedures for this)

3. Input level is adjusted both on the Maestro XL amp and from your processor. Start with the Maestro XL
level about ½ way and adjust up or down as needed.

Stereo (Two-Channel) - Hookup

First you must determine your hookup scheme. Your choice of hookup will be determined by the capabilities of
the rest of your system. The Maestro XL has RCA, line-level inputs and Speaker Level Converters are also
provided for speaker level connection. Select from the following and then make adjustments:

A) Two Channel Systems that do NOT have preamp outputs:

1. Hookup with Speaker Cable using Speaker Level Converters

This is sometimes referred to as "bass augmentation". The main speakers are run full-range and the
subwoofer is used to augment or fill in just the lower bass. Connect a second set of speaker cables in parallel
with your existing speaker cables. This set of cables is run to our speaker level converters, which plug into the
subwoofer left and right inputs. (If using stereo subs you will run one cable to each sub). Set crossover, the
input level, and phase control to get a seamless blend with your main speakers.

10

* Note: Only one channel shown

2. Hookup with Shielded Interconnect using Speaker Level Converters

Connect speaker level converters in parallel with your main speakers. Connect a female to female RCA
adapter to the speaker level converter and use shielded RCA interconnect cables to connect to the
subwoofer. (If using stereo subs you will run one interconnect to each sub). (DH Labs Subsonic Cable is
perfect for this application.)

* Note: Only one channel shown

B) Two Channel Systems that DO have preamp outputs:

1. Separates or Integrated Amp with Preamp outputs & Main amp inputs

Use Y-Adapters to split the signals from the left and right preamp outputs. Connect one end of each Y­Adapter to left or right main amp input, (using RCA interconnect). Use proper lengths of shielded
interconnects to connect the other ends of the Y-Adapters to the right & left inputs on the sub. (If using stereo
subs you will run one interconnect to each sub).
Your main speakers will receive a full range signal. To reduce low frequency content to your main amp and
speakers, use optional High Pass Filters plugged into the main amp inputs.

11

*Note: Only one channel shown

Stereo (Two-Channel) - Adjustments

Adjusting the Maestro XL for Stereo:

1. Set Initial Adjustments: Crossover frequency: 80Hz, Phase: 0 degrees with lowpass, Level: ½ way

2. Adjust Phase: Adjust volume level so sub is audible with an 80Hz test tone from the included test CD.
Switch between 0 and 180 degrees to find maximum output at the listening position. This is most easily
accomplished with an extra person to work the switch / control. If using an SPL meter such as the Radio
Shack, it might be easier to track the change with the 80Hz Warble tone rather than the 80Hz Sinewave.

3. Adjust Level: Start with input level all the way down and set crossover frequency filter to 35Hz. As you
play music with a repetitious bass line, adjust the input level upward until it is just consistently audible.
The low bass should fill in naturally. You are looking for bass that goes deeper, not necessarily louder.

4. Adjust Crossover Frequency: With the frequency filter at 35Hz, gradually adjust upward until the bass
seems full, without any missing notes , and then back off just a bit. Adjust up or down until the subwoofer
best matches the cutoff of your main speakers. The most natural results will be with the lowest crossover
point that doesn’t leave a “gap” in the response. Lower crossovers will allow the subwoofer to audibly
“disappear” and placement is less critical.

5. Fine-tune: Sit back and listen with a variety of music. Make any changes one at a time to fully assess the
effect. Take your time!

Troubleshooting Setup and additional considerations

• If you try to use the sub to adjust for recordings that lack bass you'll go nuts, adjust the sub to well
recorded music and leave it alone. You'll never get it perfect for all music because the music isn't
recorded consistently!

• If the music seems to lack warmth, try adjusting the frequency control up just a bit at a time. Too much,
and the sub becomes easily audible by itself.

• If your main speakers have ports (vents) try stuffing them; this sometimes improves the transition
drastically. The ports can easily be stuffed with cloth. Just stuff it so that you no longer get air pressure
coming from the vent when the speaker is playing. Stuffing the port changes the response from fourth
order to second order and yields a more gradual rolloff in the main speakers. It can make all the
difference in the world!

• If you have a problem with hum there are generally three possible causes:

1. Ground loops or power issues are the most common cause of subwoofer hum. Turn everything off

and remove all connections from the Maestro XL amp to the rest of the system. Turn the Maestro XL
amp back on. If the hum is gone, the problem was probably caused by a ground loop. In this case,
you will need to either use a "cheater" plug on the power cord, or use a GLE (Ground Loop
Eliminator), available from Radio Shack. If the hum is still there, plug the Maestro XL amp into an
outlet on a different house circuit. If the hum is gone, it might be a matter of the subwoofer picking up
interference from something in the house electrical system such as fan speed control or light dimmer.
Use a different outlet. If the hum remains, continue to step #2.

2. Poor connections or RCA interconnects can cause hum. If you move the shielded cable that

connects the Maestro XL amp to your system and you hear a change in the hum it is likely you have
poor shielding or a defective RCA plug. Replace the cable.

3. Amplifier damage is the least likely cause of hum. However, if you have ruled out ground loops,

power issues, or a defective connecting cable, it is possible that there is a problem with the Maestro
XL amp. Contact ACI service for assistance.

12

Other System Considerations

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. CD and DVD players, turntable,

cartridges, pre-amps, amplifiers, (receivers) 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
Ferrari, and you shouldn’t use inferior components with a high quality speaker. Your ACI Maestro
XL(s) performs like subwoofers costing far more. Keep this in mind when selecting the rest of
your system.

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, DVDs and CDs. There are more good quality recordings available now than just a few
years ago, but poor recordings with rolled off low bass, harsh and constricted mids and highs and
little stereo 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.

Avoiding Damage

Audio Concepts, Inc. speaker systems are designed for the purpose of accurate reproduction of music in

the home. We do our best to make our speakers rugged and reliable. We invested effort in the Maestro XL to
make it as indestructible as possible. We’re happy to say that after producing and selling the Titan Series for
years we’ve yet to have one blown driver returned! Of course there’s always Murphy’s law! Under certain
abusive conditions it may be possible to overdrive the Maestro XL. This is possible with your receiver or pre-amp
volume control way up with excessively high distorted signal levels.

MORE IMPORTANTLY, as reliable as the Maestro XL has been designed, you still need to be careful not

to over-drive and damage your main speakers. So please read over the following causes of speaker failure:

Remember, just because you added the power and bass response of the Maestro XL, your main

speakers won’t handle any more power than before.

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

A) If it sounds at all distorted, turn it down. Distortion is a warning sign that should not be ignored.
B) Don’t use tone controls or equalizers if possible. IF you must use them, monitor the system carefully.
C) 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.

In over twenty-nine years of daily evaluation of all types of speakers on everything from ten to one

thousand watts with all kinds of music, we have never damaged a driver without hearing audible distortion. If it
sounds bad, turn it down, and you will never damage a speaker.

13

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

Allow at least 60 to 70 hours of playing time before your new ACI Maestro XL(s) will sound the 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.

For quicker break-in:

-Play the Maestro XL(s) at medium-high volume while away from home. Use music with a lot of low bass
content. A CD or DVD player on repeat works fine.

Troubleshooting

Occasionally we get a call 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 letter 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, no 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 or write, please try to
narrow down the problem and eliminate other factors. 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
