Detailed Description
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. 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.
