The Dynaudio Esotec Automotive loudspeaker series exudes all of the virtues in Dynaudio’s long-standing tradition of high performance loudspeaker designs: Highly-evolved Dynaudio technology, meticulously selected components, painstakingly matched materials and carefully voiced sonics.
Every technical detail is developed and manufactured exclusively by Dynaudio in the company’s state-of-the-art production facility in Skanderborg, Denmark. Dynaudio loudspeaker systems exhibit no sonic character other than that of the recording, and are renowned for their ability to portray an accurate, uncolored reproduction of music. Music the way it was intended to be heard.
Soft Dome Tweeter MD 102
The Dynaudio Esotec mobile loudspeakers follow in the longstanding tradition of the company's renowned home audio driver designs. The new Esotec MD 102 tweeter is a soft-dome design as characteristic of Dynaudio. The fine soft dome features a special coating to facilitate an extended high frequency response free of distortion. The compact, shallow depth MD 102 tweeter features a 28 mm (1.1 inch) diameter surface area that is approximately 60% greater than that of conventional car audio tweeters. The optimized dome geometry provides greatly improved dispersion characteristics, enabling the MD 102 tweeter to offer exceptional performance even when mounted off of the listening axis. The dome coating serves to eliminate any high frequency break-ups, while providing improved damping. To eliminate high frequency distortions caused by reflections from inside the structure, the MD 102 tweeter rear chamber is also sealed and acoustically damped to eliminate high frequency distortion, which could be caused by backwave reflections, while ferrofluid cooling adds damping and additional power handling.
The extremely smooth and incredibly detailed high frequency reproduction characteristic of the Dynaudio sound is ensured by the all-new Esotec soft-dome tweeter, which featuresthe latest Dynaudio technological innovations. For the most authentic high-frequency reproduction – powerful Neodymium – one of the most efficient but also most expensive magnetic materials for loudspeaker construction is used in the tweeter magnet systems.
The soft-dome tweeter design topology allows unrestricted dynamics and a linear frequency response with extremely low distortion. The MD 102 features an aluminum voice coil, another Dynaudio hallmark, which has been updated and improved via an increased coil height with additional windings to allow an increased range of linear excursion within the magnetic field. Furthermore, as a result of the low moving mass of the new voice coil, a higher maximum output level and increased dynamics are achieved, while the frequency range has been expanded, thus allowing a better integration with the upper midrange frequencies to deliver a more natural sound with an open and detailed, and incredibly transparent reproduction of the high frequencies.
Woofer MW 152
The Dynaudio Esotec mid/woofers also utilize the same core technology as the company's home audio and professional studio loudspeaker products, with materials and parameters fully optimized for the particular conditions typical of in-car installations. All Esotec models are available in various sizes, all characterized by an ultra linear frequency response and Dynaudio’s exemplary sonic performance.
The most compact of the new Esotec car series mid/woofers, the new MW 152 is a compact 15 cm (5.75 inch) diameter driver with a 75 mm (3 inch) diameter voice coil. As is the case with the full range of Dynaudio woofers, the cone diaphragm is composed of a proprietary MSP (magnesium silicate polymer) material developed by Dynaudio – a low-distortion material characterized by a lack of coloration that proves essential to the unique Dynaudio sound. The MW 152 exhibits a smooth frequency response both on- and off-axis, with incredibly low distortion. The MW 152 delivers excellent midrange reproduction and is the perfect choice for any small, high-performance two or three-way system.
The woofer motor assemblies of the Esotec mid/woofers are built into torsionally rigid die-cast aluminium baskets (a high strength stamped steel basket is utilized on the MW 162 GT and MW 182 model variants), which have been optimized to eliminate air turbulence and resonance and the adverse effects of such. The aerodynamically shaped ribs of the Dynaudio die cast driver frames serve to eliminate virtually all reflections and tonal aberrations created by the traditional driver frame, and ensure the highest degree of mechanical performance at an extremely low weight.
The low suspension compliance of the MW 152 makes it perfectly suited for smaller enclosures typical of most in-car installations, while also allowing it to be utilized without a dedicated enclosure in free-air mounting applications.
Esotec X 252 Crossover
The new Esotec X 252 crossover is a competition grade, audiophile quality passive two-way crossover designed to accommodate four of the new Esotec woofers, the MW 152, MW 162, MW 162 GT and MW 172 models in combination with the Esotec MD 102 tweeter.
The X 252 Crossover is also included in three packaged Esotec two-way component systems, and features a three-position tweeter level control to better adjust the high frequency performance to listener position or preference. With the vast experience gained in developing the advanced Dynaudio premium factory sound systems offered to the automotive industry, fine-tuning the new Esotec crossovers brought forth a substantial improvement in sound quality. The Esotec X 252 is a first order crossover with impedance correction for the woofer to create an even easier load for any amplifier and a second order filter with an integrated self-resetting protection circuit for the tweeter. The Esotec crossovers all feature gold plated screw terminals, polypropylene capacitors, thick printed circuit boards with pure copper traces, and are housed in impact resistant plastic enclosures. Each is optimized for a particular configuration and is designed to enable the individual Esotec loudspeaker models to perform at their optimum capabilities while addressing a wide range of systems and applications, and are optimized for perfect phase response and time coherency in any vehicle.
