Speaker Driver Woofer 100W 8 Ohm 84dB 45Hz - 4100Hz Ø14cm
Dayton Audio's Esoteric line is the ultimate expression of the brand's knowledge and engineering finesse. Using high-end materials and benefiting from an extremely meticulous design, these transducers offer absolutely impressive performance. They guarantee a flat frequency response and a smoother damping of high frequencies, allowing efficient bandwidth expansion while facilitating the integration of filters.
Unprecedented performance for a small woofer is offered by the ES140TiA-8 thanks to a FEA-optimized motor assembly using a large circular neodymium magnet and heavy copper shorting rings. The motor geometry of the woofer is designed to provide a strong and stable magnetic field with a perfectly balanced, increasing the possible excursion range.
The huge 76mm diameter coil is wound on edge using rectangular aluminum wire and copper clad (CCAW) for maximum winding density. The ventilated Titanium coil support transfers energy to the membrane at an incredible speed while contributing to the membrane's rigidity. A woven fiberglass membrane, which allows the coupling of acoustic energy to air with excellent rigidity while allowing self-damping. The Klippel optimized suspension is designed to allow a large excursion of the membrane without distortion. The loudspeaker structure is supported by an aerated cast aluminum bowl that ensures perfect mechanical stability without internal compression.
All of these elements combine to create an innovative speaker with superb transient response and ultra-low distortion. By breaking away from established design conventions and rethinking the behavior of every part of the transducer, the ES140TiA-8 delivers excellent sound performance. This makes it an excellent choice for high-performance 2-way speaker design or for a center channel in MTM mounting.
