Item(s) for Sale: CDT Audio ES-620 GOLD
Item Description:
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.

Condition: 8/10
The woofers and crossovers are 9.9/10, pretty much in perfect condition besides a little dust, lol.
The tweeters (see pics) have some residue from the glue I used to mount them to a custom bracket for my mustang. They look a little rough around the edges but perform flawlessly.
