CDT Audio systems in the
Eurosport line utilize a 26mm soft dome tweeter a matching crossover
and a large selection of mid/woofers in either of two configurations,
separate drivers or quasi-coaxial Braxial configurations.
All mid/woofers utilize Kevlar fabric cones with semi-soft polymer
domes and rubber surrounds. These superior divers feature virtually
unlimited life and extreme "quietness". Ultra low distortion and smoothly
controlled roll-off characteristics are provided.
The specific grain oriented construction exemplified in Kevlar fabric
cones ensures that so called break-up is organized into a controlled
polar oriented vibration modality that precludes harsh bell modes
or random breakup. The result is astounding naturalness and precision.
The measurements show smooth extension and glitch-free roll-off. The
soft dome Euro tweeter has the classic dome shape and an ultra smooth
response shape. This tweeter with its' excellent power handling ability
is further cultured by the matching crossover that corrects the smoothly
sloped response shape and corrects that shape. This improved shape
is flatter and more extended as a result thereby giving the power
handling benefit of a larger soft dome with the power response profile
of a lower power handling 19 mm size driver. This is critical to natural
airy sound yet with authority.
The two drivers are then also interfaced with each other with a proprietary
crossover using an elliptical high-pass characteristic. This type
of filter utilizes intra circuit phase relationships to produce rapid
response changes. Within a narrow band signal cancellation by subtraction
occurs allowing a rapid response roll-off without the attendant transient
response smear and complexity of conventional high order filters.
A negligible group delay characterizes this rapid shift, which essentially
prevents the tweeter from interfering with the mid/woofer's smooth
roll-off. The woofer is faded out gradually and smoothly, as this
method is consistent with the best, perceived sound. The mid/woofer
since it builds the body of the sound must be faded out cleanly and
unobtrusively so the last faint high frequency sounds from it remain
realistically connected to the lower frequency body of the sound.
The result already very refined is stunningly accompanied by the rapid
introduction of the precise relatively widely dispersed (compared
to the mid/woofer at the crossover frequency) tweeter.
Overall, this is the sound of the CDT Eurosport line.
Embellishing this basic design approach are the Braxial models and
the CDT-10LP image enhancement auxiliary tweeter kit.
The Braxial models place the same 26mm tweeter in a bracket on the
driver that is off the mid/woofer axis. This ensures that the crossover
interface will occur at the proper acoustic time and in the proper
acoustic space. The off-axis orientation avoids acoustically resonant
sound spaces within the assembly. Axial designs inherently incorporate
a relatively high "Q" acoustic chamber in the region between the cone
and the back of the tweeter. The offset of the Braxial lowers this
"Q" to nil, and only one driver needs to be mounted per channel.
Many auto-sound systems cannot ideally provide for a convenient ideal
mounting position. In some cases the tweeters may need to be mounted
well below ear level. In order to embellish the extreme top end and
to lift the image (usually toward the windshield area) the CDT-10LP
Image Enhancement kit can add a dash of "air" and space to enable
the best overall special character.
