- 4th / 5th Order "Transient
Optimized Elliptic Topology" Crossovers
- Engineering a perfect compliment
to the highly acclaimed CDT drivers was an equally challenging task. "The
Elliptic" crossovers, called SatNet, are an engineering breakthrough for car
audio.
- They use an ingeniously designed
fifth order, elliptic type network that creates very distinct advantages over
conventional "Butterworth" or "Linkwitz-Riley" passive filter topologies.
This topology is so unique that this is the VERY FIRST TIME it has been used
commercially in a car audio application.
- Technically speaking, the
SatNet crossover design is a fourth order/24dB per octave design supplemented
by a series first order/6dB per octave on the front end. The unique combination
of the two creates a virtual 10th order, 60dB per octave crossover where the
critical crossover point between the mid and Tweeter is.
- The benefits of the design
are many. First, the power transition between midrange and Tweeter is virtually
identical. Phase response problems and polarity shifts are almost entirely
eliminated. What you HEAR, is a much more natural sounding component system,
as if it were that one perfect speaker. And further engineering improvement
are our "Transient optimized" designs which you find in the 560-200Z,200US
and HEX-5000.
- All combined, you have the
ideal link to some of the best car audio loudspeakers you'll ever listen
to.
- EX-450 is a new design 2007
provides the essential CDT Audio Elliptic xover topology in the most affordable
package. The two-way crossover is composed of a 5th order elliptic high pass
network for the Tweeter and first order butterworth for the woofer. Three
Tweeter levels are selectable. Tweeter protection is provided. Crossover takes
place at 4.3kHz. Mylar and film capacitors in the Tweeter network. This provides
greater power handling and clarity.

- EX-560i new 2007 is a cut
above the all the above models. In this model the high pass crossover is
replaced with a fourth order transient-optimized design. This delivers the
cleanest possible Tweeter drive. Crossover takes place at a slightly lower
3.7kHz.The first order woofer crossover has a larger zobel capacitor for
a lower crossover frequency to match. More than this a tapped inductor adds
adjustability to this woofer crossover also. This suits different driver
sizes generally. The adjustor is labeled by driver size (5.25 and 6.5). The
image Tweeter is operated 3 db below the main Tweeter at a fixed attenuation.
Protection is omitted for maximum sound quality. Terminals are 12 gauge block
terminal, more robust military grade and arranged in a dual four arrangement
versus a single line as in the prior models.

- This compact silver bullet
module implements the image enhancing StageFront Technology Upstage system
while holding complexity to an absolute minimum. This versatile crossover
module implements a two-way crossover with large high quality parts or alternately
may be programmed to drive an upstage high-mounted second Tweeter. This dual
functionality is jumper selectable. In simple two-way mode the tapped inductor
design in the Satnet 560 is used. Dual jumpers moved together change the
crossover to upstage mode. In the upstage mode the drive to the mid-woofer
and Tweeter are tapered off to interface with the upstage Tweeter. This tapering
is adjustable with three L settings and two C settings. This alters the crossover
frequency and response shape (damping). The image Tweeter furthermore has
seven selectable levels available. Upstage crossover is typically at 8kHz.
Main Tweeter crossover is transient optimized at 3.7kHz. No protectors are
used.

- CDT ES-300CC GOLD Mid-EQ
3-way xover
- Designed to produce a crossover
to the midrange around 250 Hz with a seven-inch woofer and four-inch midrange
in a typical installation, this crossover produces amazing results with ease
in a reasonable occupied space. The proprietary series connected tapped inductor
maintains damping to the midrange and woofer on all levels and interacts
to vary the crossover Q. Another similar inductor controls the midrange roll-off
or EQ to match various mid-range drivers in various mounting positions to
the selected installed tweeter. As the midrange level is reduced, the crossover
Q to both drivers is parametrically altered to automatically produce an optimal
crossover to both drivers at all selected levels.
- The midrange is equalized
to crossover to the tweeter with a purely first-order adjustable filter.
Combined with the elliptic crossover on the tweeter optimal sound quality
is achieved.
- This flexible approach will
produce the best sound in virtually all installations adapting to various
midrange drivers. The maximum setting for the midrange EQ duplicates the
HD-30 fixed setting. Choose the mounting position and select the drivers
to accommodate your vehicle and to facilitate a natural sound. A very small,
extended range speaker can also be selected to augment the tweeter response
especially if a high mounting position is chosen for the tweeter.
- Tweeter crossover is accomplished
with a transient-optimized fourth-order elliptic crossover which brings in
the tweeter quickly and seamlessly to complement a broad variety of tweeters
and midrange drivers in most locations. Crossover will typically be achieved
around 4.3 kHz depending on driver selection and relative mounting position.
Extended-range midrange speakers can raise the crossover to produce a blend
up to 10 kHz when the maximum EQ setting is chosen.
- Three-way configurations
will create an installation that gives the smoothest midrange, the most flexibility
in mounting the drivers for a smooth blend and finally gives the best bass
impact. Midrange drivers, because they are small and require minimal enclosure
volume, can usually be located conveniently close to the tweeter
- Installation of this unit
is totally straightforward and trouble-free.Terminals are clearly marked
with the designated connections and polarity. Level setting jumpers are clearly
marked and each offers 3 positions. The EQ jumper provides four positions
to select maximum (natural driver roll-off only) and three other jumper positions.
With a typical midrange driver and location this provides a tapered response
shape beginning at the corresponding frequencies:
- It should be noted the crossover
will still take place at 4-5 kHz Hi 4kHz but the EQ setting will flatten
the response of the midrange if
- Med 2 kHz necessary
in the region below the preset tweeter crossover
- Low 1 kHz frequency.
- ES-300CC adds functionality
and uses larger premium parts for the maximum performance and power handling.
This crossover module offers interactive crossover to and adjustability of
the mid-range and tweeter and a high-tech elliptic filter to crossover the
tweeter. New and unprecedented functionality in this unit is highlighted by
the superiority of the midrange level setting and the midrange crossover to
the tweeter.
- With all tone controls set
to flat, set the levels to medium and the EQ to max. With a vocal recording
move the midrange level jumper to balance with the woofer sound. Male and
female vocals both occur in this crossover frequency range. The upper EQ
end of the midrange can next be set with a recording that includes cymbals.
Try setting the tweeter level for a natural high at each of the four possible
midrange EQ settings. One of these combinations will give an optimized result.
- In the case that more adjustability
is required our CDT LP-1 may be interposed between the midrange or tweeter
driver and its connection to the crossover to dial in the desired level on
a continuously variable basis.

- "The system imaged so well
that I could imagine Dido standing on the dash board. The image of Dido was
sharply focused and placed precisely under the rearview mirror.
- With the CDT 519XT UpStage
system hooked up - all images were high (about 6-8 inches above the dash)
and out front in their correct locations, not down on the floormats. I heard
bright, crisp, and clean sound from sharp images on a high, deep and wide
soundstage.
- The sound seemed to be coming
from the windshield. Image focus was realistic and convincing. Placement
of of the musicians across the windshield stage was satisfying and compelling;
the images were off the floor and above the dashboard, and we all agreed the
CDT Audio UpStage? system successfully raised the stage. This time, my ears,
not my ankles, reaped the benefits". I was also impressed by the clarity
of the sound, even at high volume. I couldn't believe how natural is sounded.
In fact, I couldn't get enough! With the CDT UpStage system, the images were
hovering near the sunvisors."
- Review the complete CDT 519XT
UpStage system test report in Road & Track roadgear In-Car Audio Video

- This set use the smoothest
silk Tweeter you ever heard. Always gentle and forgiving, this Tweeter emphasizes
the music and avoids noise and artifacts that may embed some source material
or be characteristic of less than perfect amplifiers. Perfect for use up on
the dash or A-pillars.
- Very low listening fatigue
and an easy quality that puts an emphasis on the system's midrange. The driver
is a 3/4" silk dome cooled by ferrofluid

- -Built-In UpStage design
- -Built-In 2-3 way design
- -Built-In Mid-EQ design
- The versatile master of all
situations is achieved in one module with the highest quality parts. This
is a large module. Any of the functions above are available. Many program
modes are toggle switch selected. The mid-woofer is instantly reversible
in phase by toggle switch. This module will work in two-way, three-way and/or
upstage mode in any combination. Additionally to any of the prior modules
three transient optimized main Tweeter levels are selectable. There are 5
settings for mid-woofer upper taper which shapes the mid woofer sound as
well as the level adjustment for the upstage Tweeter.
- Crossovers are 250 or 300
Hz for the mid-woofer in 3-way mode. The upstage crossover is approximately
8kHz and the main Tweeter crosses over at 3.7 kHz. The L and C jumpers cross
over the main Tweeter and mid-woofer as a mated pair to the upstage Tweeter.
The taper and attenuation settings operate to moderate the contribution of
the mid-woofer to the midrange. All the functions of the best modules are
available. Defeat able upstage Tweeter protection is available.
- The HEX-6000 is a passive
design master system that includes all the functionality required for the
installation of a system wide four or five-way system, including the subwoofer.
This includes a switching function to select between a three or four way
passive installation. The subwoofer and image Tweeter combined with the basic
two-way crossover implements a four-way system. A pair of HEX-6000 could,
with one, two channel amplifier implement a three-way crossover by itself.
The typical optimum installation would utilize one four-channel amp with
two channels for the subwoofer and the other two for the front and rear right
and left channels. The front channels are programmed with the HEX-6000. The
rear speakers play a lesser role in enhancing the sound and we recommend they
be driven through an LP-2.
- This wide-band but low bass
filtered module adjustably attenuates the signal to the rear speakers to
just the right amplitude for acoustic rear "fill".
- Each rear speaker constitutes
an entire system typically simply consisting of a very good full range speaker
or a two-way integrated unit. A large or elaborate vehicle might employ a
model 04 with a model 01 Tweeter in an isolated chamber (enclosure) and one
or our crossover units especially the ES/HD 200Z. This module provides the
same ³zone adapter² function found in the HEX-6000. Mounting a
midrange speaker in many places in the vehicle will result in a little more
midrange than the driver designer intended. The zone adapter anticipates this
and allows the midrange driver¹s response shape to be altered. In some
cases the overall level may be increased by the mounting position, and then
using the attenuation feature is appropriate. Both the
- LP-2 and the HEX-6000 may
be connected to one amplifier channel to thereby implement one side of the
vehicle front and rear.
- The front system we recommend
uses ³Upstage² Tweeters preferably mounted on the A-pillars with
one of the mounting systems provided in our Upstage speaker kits. Our best
kits also employ the HEX-6000 and woofers having polymerized black fabric
cones with a polymer semi-soft dust-cap and rubber surround. These models
furthermore employ a shorting ring above the pole-piece to control inductance
modulation and reduce distortion. The model
- 07.2 implements a two-way
system with the HEX-6000 and your choice of Tweeters and the model 07.3 similarly
implements a three-way system. The model 07.2 uses a 7" woofer and the model
07.3 is the same except it adds a 4" mid-woofer. The HEX-6000 in each kit
will handle the crossover function with either driver complement.
- The front speaker systems
in the vehicle would typically be mounted in the door and/or kick panel areas.
The "lower" Tweeters (versus the above dashboard upstage Tweeters) are mounted
as high as practical to blend with the upstage set. One setting in the HEX-6000
will adjust the level and the gradual crossover frequency to the upstage
Tweeter pair. Since the "lower" Tweeters are low-pass filtered by the HEX-6000
and the upstage Tweeters are closer to the ear, the acoustical level of the
"lower" Tweeters will always be less than that of the upstage pair. This
level is therefore fixed. The two-way system, which combines the ³lower²
Tweeters with one of the cone drivers, is also adjustable relative to the
upstage system as is the level and slope of the midrange roll-off within
that system. Thus there is adjustment within adjustment to obtain a critical
balance from the all-important front system. These adjustments have particularly
appropriate predetermined filter slopes and frequencies to optimally interface
the drivers in this area. Trying to do the same thing with an active multi-channel
system would be very challenging and the driver integration would almost
certainly be inferior.
- The next step is to adjust
the elements. Either the three-way (five-way including a sub and image Tweeters)
or the two-way (four-way system including a sub and image Tweeters) can be
adjusted by using this procedure.
- Turn the subwoofer all the
way down (no bass) and remove the image Tweeter jumper (it may be installed
sideways to store it with no effect on the sound) this mutes the Upstage
and subwoofer parts of the system. Set S1 to two-way. This will mute the
woofer if installed. Now only the mid-woofer and ³lower² Tweeter,
are playing. Set the M-W phase to + . Adjust the high pass crossover to the
lowest frequency to supply nearly full-range bass to the system.
- The system is now reduced
to a two-way system. There are four settings that will now act on the midrange
portion and two on the Tweeter. The functions L-frequency and C-frequency
act on both drivers and the M-W attenuator and M-W taper act only on the
mid-woofer. Only two settings need to be adjusted at one time.
- The next step is to preset
these four settings as follows:
- L-Frequency to Hi
- C-Frequency to Hi
- These remain fixed during
this step.
- M-W Attenuation to 0 (zero)
- M-W Upper Taper to MIN
- The next step is to adjust
these settings to provide a smooth response with a gradual roll-off on the
upper and lower frequency extremes. Since the mid-woofer is driven full range
the balance on the lower end will extend into the bass. This is helpful in
judging the sound subjectively.
- You can use a test disk and
a microphone but these must ultimately be put aside for a final setting by
ear. If using instruments set the drivers position for a flat response using
the two jumpers. On the other hand if working by ear the following comments
may be helpful.
- The design situation here
is that the mid-woofer and closely associated Tweeter will be mounted down
in an area that that acoustically boosts the woofer sound and misdirects
and absorbs Tweeter output. The upper end of the mid-woofer will suffer the
same fate as the Tweeter. The M-W Upper Taper attenuates the upper end of
the woofer so the Tweeter will be proportionally higher in output. The M-W
Attenuator lowers the entire range of the mid-woofer to bring the broad range
of the driver down. Lowering the mid-woofer restores the proportion of high
frequencies.
- The sound should be smooth
and natural without blaring or getting nasty in any way. Basically you want
to move the attenuator until the Tweeter is well proportioned. Next you want
to try the Upper Taper to best blend the drivers. This is a more restricted
adjustment.
- If vocals and especially
the saxophone are prominent the midrange is too strong. If this is an M-W
Level problem the highs will lack energy.
- Remember, at this point the
upper highs are absent and the highs will always lack bite. The midrange
is being set so the Tweeter will blend smoothly into this midrange. If the
sound is perfect and natural the M-W attenuation and Upper Taper can be left
alone. If there is some harshness (or brightness to some) move the M-W
Attenuator jumper down toward -6. At 6 the Tweeter will be standing out.
Gradually move this jumper up and down. Choose the best setting. This is
really a balancing act between the upper bass and Tweeter level.
- Next you want to properly
blend in the upper midrange. Move the M-W taper up and down until the lower
highs sound natural. There should be plenty of range to make the mid-woofer
level upper range too low.
- This balancing act is easiest
to set now with the L and C frequency set to HI. Typically both of the Attenuation
and Taper jumpers will be a few steps down from the top. Listening to harmony
as in a vocal quartet can help also in arriving at a final decision. There
are 35 possible settings. This should quickly be reduced to less than 10.
If the Tweeter starts sounding separate, raise the midrange taper toward ³MIN²
and if the male vocal or harmony among voices sounds unnatural rebalance
the M-W attenuation.
- The next step is to add the
Upstage. It is unlikely the Tweeter will be damaged but the S-Tw Fuse jumper
can be in either position for the next step.
- The L and C Frequency jumpers
are going to act to low pass and shape the upper end of the two-way system
you just tuned to interface with the Upstage Tweeters.
- Turn the S-Tweeter Level
jumper around or retrieve it and put it in the Low position. You will immediately
hear top end. The idea is to balance the level of lower midrange sound with
the top end. This may not blend optimally at first. The highs could be too
³brassy² try massed brasses as found in a marching band.
To control this ³brass edginess², move the L-frequency jumper down
one or two steps. After this readjust the Upstage S Tweeter Level to
restore an overall natural balance. Now try the C-Frequency jumper in the
Low position. If this seems more natural, it will preferentially accentuate
the lower highs slightly, leave it in and retune the settings slightly to
bring the system to optimal balance. At this point the system should sound
very good but bass shy. When the bass is added you will usually want to raise
the Upstage level a notch or even two to balance the added bass weight. Up
till now the system will have sounded more natural with the Upstage Tweeters
down a bit to compensate for the lack of bass.
- If the system is a three
way only, toggle S1 to the three-way position. Now the extra woofer is engaged.
The concern here is that the new driver crossover cleanly in the lower midrange.
To insure this, toggle the M-W phase switch. Again select the most natural
sound. Try the M-W lower taper in the Hi and Low positions. Check the phase
again. There are only four combinations here. The lower piano keys and plucked
bass should sound tight and yet rich. If the Woofer is still a bit prominent
the entire rest of the system already adjusted can be brought up slightly
by moving the M-W Upper Taper and Attenuation and S-Tweeter Level up perhaps
one step or even two. As each driver is added the overall system can be fine-tuned
to best work with it.
- Finally adjust the subwoofer
to work with the system as it is now. Raise the high pass and low pass filters
in the Amp or external crossover if used. Adjust the subwoofer level and phase
for clean fast bass. There are four adjustments and at least three will be
continuous over a range.
- Take note that any driver
can be deliberately wired to the module in reverse if it works better that
way. The one unlikely possibility is to have the woofer in the three way
system ³inverted² while the Mid is in the + position.
- The one pitfall is to avoid
having the woofer in the three-way system be too efficient and out of proportion.
Purchasing CDT drivers assures that the sensitivity and impedance will be
compatible among all the drivers. If the driver is in a deck, door or kick
panel with a large empty volume of air behind it a small resistor in series
perhaps two or three ohms will lower the level and add mid-bass punch.
- The HEX-6000 coordinator
has now perfectly aligned the entire system.
