features
Molded woofer basket - The backbone of any good woofer is its basket. It provides the proper
alignment and support structure for the magnet and moving parts while the very thin braces guarantee
a minimum of early reflections off the basket that would be ordinarily transmitted as sonic colorations
through the cone.
Woofer cone - Anodized polypropylene provides the right combination of rigidity and low moving mass
for low distortion and excellent frequency response.
Vented voice coil - Magnet cooling vent construction enhances power handling capabilities of the
woofer
Extended center pole - Woofer magnet geometry provides a symmetrical magnetic pattern to reduce THD.
Tweeter - Ultra-light silk dome design is treated with polymer compound to control all non-linear
resonances.
Multi-mount tweeter - The following tweeter mounting options are supplied to mount the ferrofluid
cooled neodymium tweeter: coaxial, surface, angled surface, flush, or angled flush.
Tweeter level control - A three-position switch adjusts the volume of the tweeter with respect to the
midrange.
Tweeter Phase switch - A two-position switch which allows 0° or 180° phase difference between the
tweeters and midranges.
Bi-amplifiable/ bi-wirable - The passive crossover supplied with this system is bi-amplifiable or biwirable; typically only available in high quality audiophile home loudspeakers.
Solid state tweeter protection - Advanced protection circuitry provides protection for the tweeter
against overpowering or amplifier clipping.
cautions
Study your automobile thoroughly before you drill or cut any holes. Take extra care when working near
gas tanks, gas lines, brake or hydraulic lines and electrical wiring.
Wear eye and ear protection when using power tools. Keep the woofers and tweeters away from metal
filings and shavings. Once foreign objects are stuck to the magnets or tweeter dome, it will be virtually
impossible to remove them. Keep the tweeters in their protective bags until final mounting to prevent any
possibility of metal dust or chips from passing through the grille and accumulating on the dome.
Exercise caution when working with the ix series with the grille removed. A slip of the hand with a
screwdriver or other tool can result in irreparable damage to the cone. Do not touch the cone.
Do not install the components where they will be subject to excessive heat, moisture or dust, or where
they will be kicked or repeatedly bumped or brushed.
Make absolutely sure that the woofer is connected to the lowpass output and the tweeter is connected
to the highpass output of the crossover network. If these connections are reversed, low-frequency signals
will be fed to the tweeter without fuse protection. In this case, the tweeter may be damaged, such
damage is not covered by the warranty.
2
When removing or installing the grilles, be careful not to brush the woofer's rubber surround or the
tweeter's dome with the edge of the grille. Cutting or tearing the surround or dome will destroy the unit.
Never run wires outside or beneath the vehicle where they can be snagged by road hazards or the moving
parts of the vehicle. Use existing wire channels, sills, panels and molding strips inside the automobile to
hide the wiring for neat appearance and safety.
Make sure your radio/cassette/cd player and or other equipment is turned off while connecting the
speaker terminals. Turn on the various components and slowly advance the volume control ONLY after
checking and double checking all connections.
NOTE: If the sound is weak or distorted, immediately turn down the volume and see the section entitled
Troubleshooting.
installation planning
Proper installation planning is the best way to maximize performance. By planning your installation
carefully you can avoid situations where the performance or reliability of your system is compromised.
Your authorized a/d/s/® dealer or a/d/s/® audio technical support at 1-800-753-0800 x2033 has been
trained to know how to maximize your speakers sonic potential. They are a valuable resource in helping
you with your system design and installation.
amplifier requirements
This speaker system requires a minimum of 45 watts per channel to achieve reasonable listening volumes
in a moving automobile without clipping the amplifier. a/d/s/® recommends 150 watts per channel as a
maximum so as not to exceed the thermal or mechanical limitations of the speaker system. Any amplifier
between 45 watts and 150 watts may be used. If you choose to use an amplifier with more than 150
watts use caution as speaker damage may occur at high volume settings. All a/d/s/® loudspeakers will
produce reasonable volume levels in the automotive environment using moderate amplifier power.
However, the use of a low powered amplifier to try and attain very high volume levels can lead to
overdriving the amplifier and damaging the speaker system. As a rule, do not turn the volume up above
the point where you hear distortion on musical peaks from either an overdriven amplifier or mechanical
noise from an overstressed speaker. For the best performance and reliability; select an amplifier with
slightly more than the maximum power you are likely to need to generate the desired volume levels. This
margin of reserve power will ensure that the amplifier will not be routinely driven beyond its design limits.
WARNING: Excessive sound pressure level can permanently damage your hearing. The maximum volume
levels attainable with a/d/s/® speakers, combined with high-power amplification, may exceed safe levels
of extended listening.
mounting locations
There are many possible choices of mounting locations. The vehicle factory locations will usually dictate
the woofer mounting position. Because of its small size and multiple mounting options, the tweeter can
virtually go anywhere. a/d/s/® uses an unusually low crossover frequency for the tweeter which means you
are not restricted to mounting the tweeter close to the midrange speaker. The tweeter can be mounted
as far as 24" (60 cm) from the midrange speaker without causing adverse effects on the sound quality.
However, better results are usually obtained by locating the tweeters and midranges relatively close to
each other, and by keeping the sound path lengths between the listener and the left and right speakers
as equal as possible.
a/d/s/® cannot recommend specific tweeter mounting locations for each vehicle, but in general try to keep
the tweeters as far to the sides of the car as practical. Avoid placing them above ear level unless the
woofers are also above ear level. Place the tweeters in similar locations on both sides of the vehicle. Try a
few locations by just placing the tweeter or taping it in a location and listening to ensure the desired
stereo image and high frequency dispersion are achieved before committing to a location by drilling holes
in the vehicle. You should also experiment with the tweeter phase switch settings to find the most
effective combination of location and phase.

Select the Bi-amp position if you intend on driving the woofers and tweeters with separate amplifiers (four
channels). Select the Parallel position if you intend on driving the woofers and tweeters with the same
amplifier (two channels).
Tweeter Level switch
The three position switch in the crossover adjusts the output level of the tweeter. The mid-position (0) is
referenced as equal output from the midrange speaker and the tweeter. The high position (+3) provides
3dB more output from the tweeter. The low position (-3) provides 3dB less output from the tweeter. Select
the position of this switch for your listening preference.
Tweeter Phase switch
Selects 0 or 180 degrees phase relationship between the tweeters. Select the position of this switch for
your listening preference.
Tweeter Thermal breaker
This component protects the tweeter if too much power is delivered to the tweeter. If activated, the
tweeter will briefly stop producing sound until the breaker automatically resets.
Tweeter DC Clip protector
These components limit the amount of current delivered to the tweeter if overdriven by either excess
amplification or clipped signal from an overdriven amplifier.
Connections to the amplifier
The crossovers are supplied with removable screw type connectors. The crossovers have two sets of input
terminals, this allows the system to be driven by either two for four channels of amplification. To correctly
use these wiring schemes, you must move the Bi-amp/Parallel switches to the desired position.
To bi-amplify the system you will need 2 stereo amplifiers (or 4 amplifier channels) with one pair of
channels to drive the tweeters and one pair to drive the woofers. In this configuration, the Bi-amp/Parallel
switch must be set to Bi-amp.
4
You may also Bi-wire the system by connecting the woofer input terminals to the amplifier and connect
ing the tweeter input terminals to the same amplifier with another set of speaker wires. This is sometimes
done to allow a specific high frequency or low frequency cabling to be used for the two separate signal
paths. See Crossover Installation for additional information on bi-wiring.
Be sure to connect the positive crossover terminals to the positive speaker terminals and positive amplifier
terminals, also ensure that the negative crossover terminals connect to the negative amplifier and speaker
terminals. Once all of the wires are attached to the connector and the crossover is mounted, the
connector can be plugged into its mating receptacle on the crossover.
speaker wiring
Speaker wire selection
Use insulated two-conductor stranded wire to connect the crossover to the speakers and amplifier. The
size of the wire can have an audible effect of the performance of the system. Stranded 18 gauge "zip
cord" will work, but can result in lower output or unpredictable frequency response. For wire runs of 50
feet (15 m) or less, we recommend 16 gauge or larger wire. The crossover connector will accept up to 14
gauge wire.
Polarity and phasing
The polarity of the positive/negative orientation of the connections for every speaker and amplifier
connection must be consistent so all the speakers will be in phase. When the polarity of one connection
is reversed, bass output may be reduced or stereo imaging degraded. Most speaker wire is marked so you
can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor, or the
wire may have clear insulation with different color conductors (copper and silver). There may also be
polarity indications printed on the insulation. Identify the positive and negative conductors and be
consistent with every speaker and amplifier connection. The supplied speaker wire has a white stripe to
indicate the (+) positive conductor.
Termination
The woofer uses an angled locking screw connection integrated to the basket of the speaker. The tweeter
wires are terminated with molded connectors (male and female). Use the supplied wire with insulated
connectors to extend the tweeter wires to the crossover section. Alternatively you may solder the tweeter
wire connections and insulate them with high quality heat shrink tubing.

speaker installation
Woofer installation
The woofer will fit into many standard factory mounting locations using the existing mounting holes in
the automobile. Remove the trim panels and inspect the installation locations before you cut and drill the
holes required to mount the woofer. Removing the panel will also make it much easier to route wiring
inside the door. Look for original equipment speaker installation cutouts that can be used to install the
woofers with little or no modifications. Use the supplied template to help you locate and mark the holes
needed to install the speakers.
If the planned installation location is in a door panel be sure the speaker will not interfere with the
window lowering mechanism. Ensure that the speaker wires are positioned to clear all moving parts inside
the door.
For each woofer you will need to cut one large hole and drill small holes around the circumference. If the
mounting surface is covered by carpet or fabric, use a knife or razor to cut the material away from the
holes to be cut. This prevents material or fibers from becoming tangled in the drill bit or cutting blade. If
you are using the packaged metal screws provided in the hardware kit, drill the four speaker mounting
screw holes with a 1/8"(3 mm) drill.
Clean the work areas of all filings and shavings with a vacuum cleaner before you proceed with woofer mounting.
Woofer mounting
Route the speaker wire from the woofer installation locations to the crossovers. Pull the wire through the
installation hole and attach the terminals on the ends to terminals connections on the speakers. Refer to
the speaker wiring section of this manual and the wiring diagrams. Push the wire back into the area
behind the installation location and be sure it will not interfere with the speaker or get snagged by any
mechanisms in the area.
Attach the supplied foam gasket strip to the mounting surface of the speaker. This will ensure an air tight
seal, which is required to achieve the best bass performance.
Install the speakers by gradually tightening each mounting screw. Tighten the screws until the speaker is
well seated, but take care not to over-tighten.
tweeter installation
This speaker system is supplied with five different tweeter mounting options, coaxial, surface, angled
surface, flush, and angled flush mount. After you decided which option is best suited to you installation,
refer to the following sections for specific details on mounting the tweeter.
Coaxial mount
These components have the unique ability to also be used as a coaxial speaker in specific applications.
This allows the tweeter to be placed directly in the center of the woofer without obstructing the voice coil
or the function of the woofer.
CAUTION: Use caution to not damage the speaker cone in the procedure described in the next steps.
Unscrew and remove the center bullet from the threaded mounting post by turning the bullet
counterclockwise as shown in the following illustration. Retain the bullet for future use.

Install the tweeter into the extension housing by first threading the tweeter wires through the extension
housing and then installing the tweeter into the mounting slots of the housing and turn the tweeter
counterclockwise to lock the tweeter in place.

Now feed the tweeter speaker wires through the front center of the woofer (where the aluminum bullet
was removed) As shown in the next illustration. Align and thread the coaxial tweeter assembly on the
threaded post in the center of the woofer. Rotate the coaxial tweeter assembly clockwise until snug.
Connect the tweeter wires to the tweeter output from the crossover.
The tweeter is mounted at and angled relative to the woofer. Before final woofer mounting, rotate the
woofer so that the tweeter is pointed in the desired direction, typically towards the listener’s ear location.
Surface mount
The preparation of the mounting surface for the tweeter involves drilling three holes. Two holes are for
the mounting screws. Their centers must be spaced 15/16” (24 mm) apart. Use a 1/8" (3 mm) drill bit for
the supplied screws to mount the cup. The third 1/4” (7 mm) hole is required for the wire to pass through.
Use the template provided to locate the hole centers. Cut carpeting or fabric away from the hole locations
to prevent tangling of fibers in the drill bit.
Surface mount cup (Straight or Angled)
Mounting slots (qty 4)

(qty 2)
Insert two #6 x 3/4" flat head sheet metal screws through
the holes in the bottom of the surface mount cup. Screw
the cup in place. Ensure the mounting screws are driven
in straight, so the heads sit flush on the cup mounting
surface. This ensures the tweeter will seat properly in the
surface mounting cup. The tweeter is then slid into the
mounting cup (tabs aligned with the mounting slots), and
turned counterclockwise to lock in place.
NOTE: The mounting cup is also supplied with an angled
surface mounting cup (not shown). This allows the
tweeter to be mounted at an optimum acoustic angle for
the listener. Follow the same procedure as above to
mount and assemble the tweeter in this housing.
Flush mount (Surface or Angled)
NOTE: Ensure that there is enough clearance behind the mounting surface for the M4-0.7 X 4-1/2 cm
(1.77 inches) flat head mounting screws. Reduce the length of the mounting screw as necessary to meet
clearance.
Check the intended installation site to be sure
that there is sufficient depth behind the
mounting surface for the rear cup and
mounting screws. The minimum depth required
behind the back of the mounting surface is 1"
(25 mm). The front cup mounts into the
mounting through a 1-7/8" (48 mm) diameter
hole. Be careful that the hole does not exceed
2-1/8" (55 mm) diameter at any point so that
the rim of the cup will completely cover the
edge of the hole.

Mounting Cup
Insert the two M4-0.7 X 4-1/2 cm (1.77 inches) flat head metal screws through the mounting holes and
just start the threads into the metal mounting bracket. With the metal bracket attached to the mounting
cup slide one end of the metal bracket and then the other end into the mounting hole. Hold the mounting
cup in its final position and tighten, but do not over tighten the two mounting screws.
NOTE: The mounting cup is also supplied with an angled surface mounting cup (not shown). This allows
the tweeter to be mounted at an optimum acoustic angle for the listener. Follow the same procedure as
above to mount and assemble the tweeter in this housing.
Tweeter mounting
Route the wire from the crossover locations to the tweeter locations. Pull the wire through the mounting
cup and attach crossover wires to the wires from the tweeters. Connect the positive wire to the positive
(+) terminal of the tweeter, which is marked with the white trace. Ensure the tweeter connection spade
lugs are wrapped with electrical tape or covered with heat shrink tubing. See the information in the
speaker wiring section of this manual and the wiring diagrams. Push the wire back into the area behind
the installation location and be sure it will not interfere with the speaker or with anything behind the
mounting panel. To attach the tweeter to the surface or flush mount assembly, align the tabs in the
mounting cup with the relieved areas in the tweeter mount and twist the tweeter counterclockwise until
locked in position.

crossover installation
The system supports conventional wiring, Bi-wiring or Bi-amping using the supplied passive crossovers.
While conventional (parallel mode) wiring will provide excellent sound, bi-wiring or bi-amping may further
enhance the performance in no-compromise systems.
Bi-wiring uses a separate pair of speaker wires for the high frequency and low frequency signal between
an amplifier channel and its associated crossover network. This gives you the option of choosing wire
which may have slightly different sonic characteristics in order to optimize performance of each frequency
range. Also, it reduces the overall wiring resistance between the crossover and amplifier, much like the
use of larger gauge wire. This option provides the most benefit when the crossover network is mounted
a long distance away from the amplifier. If the crossover is mounted close to the amplifier it is doubtful
that there will be an appreciable difference between bi-wiring and conventional wiring.
Bi-amping uses a separate amplifier channel for the high-frequency and low-frequency sections, instead
of the single amplifier channel used in conventional and bi-wired connections. Bi-amping provides the
additional advantage of allowing use of the amplifier's level controls to provide an additional level of finetuning not possible with the tweeter-level switch alone. In addition, at high power levels, a bi-amplified
connection can help protect the tweeter from amplifier clipping, which is more likely to occur on channels
driving the midrange. When bi-amping using the passive crossovers, the midrange low-pass filter and
tweeter high-pass filter on the amplifier or external active crossover should be bypassed.
Carefully route the wires from the woofer and tweeter to the crossover mounting location. The crossover
installation location should be reasonably accessible to allow easy connection of the wires and adjustment
of the internal switches. If the crossover must be mounted in an inaccessible location make the speaker
wire connections and adjustments before final installation. Be sure the installation location has adequate
clearance to allow the removal and replacement of the cover. Mounting the crossover requires removing
the top cover of its housing. Grasp the top cover at the front and back. Compress the cover slightly in the
center and lift it off the bottom of the housing. Mounting the crossover requires four holes in a
rectangular pattern 2 13/16" x 4 1/4" (7.14 cm x 10.8 cm) on a flat surface. Use the crossover as a
template for drilling the mounting holes.
10
Align the mounting holes in the bottom half of the crossover unit with the holes you have drilled at the
installation site. Pass the four #6 x 1 1/4" screws through the holes in the crossover unit, and tighten them
until the assembly is firmly in place. As before, do not over-tighten; this is especially important if the
mounting surface is not perfectly flat.
After all the connections and any necessary adjustments have been made snap the cover back in place.
connecting the system
Trim the speaker wire as needed. Strip about 1/4" (6 mm) of the insulation from the ends. Twist the
exposed strands thoroughly to prevent any loose strands from causing a short circuit. You may also "tin"
the wire with a soldering iron. The wires attach to a removable connector which in its assembled position
has the screws facing the bottom of the crossover. Insert the prepared wire into the appropriate location
(see diagram or refer to the crossover circuit board) in the connector strip and tighten the screws to secure
the wires in place. Be sure to note the polarity marking on the circuit board.
crossover connections and input switch setting
Route the wires connected to the input terminals on the crossover network to the power amplifier.
Connect the wires to the amplifier outputs as recommended by the manufacturer of the unit. Make sure
there are no stray strands of wire which could cause a short circuit. Observe left/right polarity markings.
