ES140TiA-8 5-1/2" Esoteric Series Woofer 8 Ohm
Now with improved frequency response for easier crossove
Notify me when back in stock
Dayton Audio's Esoteric Series is the ultimate expression of Dayton Audio’s transducer engineering knowledge and finesse. Featuring high-end materials and advanced engineering throughout, the Esoteric Series collection of drivers elevates the state of the art in driver design. Now with a flatter frequency response and smoother high frequency roll-off allowing for extended bandwidth and easier crossover integration.
Unprecedented performance for a small woofer is packed into 5-1/2" ES140TiA-8, thanks to an FEA-optimized motor assembly using a large neodymium ring magnet and heavy dual copper shorting rings. Dayton Audio's Esoteric Series' woofer motor geometry is designed to provide a powerful, stable field with excellent saturation and symmetry, expanding the usable range of excursion.
The huge 3" diameter voice coil is edgewound using rectangular copper-coated aluminum wire (CCAW) for maximal winding density within the coil profile, and the ventilated titanium voice coil former transfers energy to the cone with incredible speed while contributing added stiffness to the cone itself. A woven glass-fiber cone couples acoustic energy to the air with excellent stiffness and self-damping, while its shallow profile minimizes cavity resonance. The Klippel-optimized suspension is designed to allow high excursion of the cone without distortion, and the structure of the driver is supported by a fully ventilated cast aluminum frame for supreme mechanical stability without internal compression.
All of these elements combine to create a driver that breaks new ground with superb transient response and ultra-low distortion. By breaking free from established design conventions and rethinking how each part of the driver should behave, the ES140TiA-8 consistently delivers a musically accomplished performance, time after time. It’s an excellent choice as a woofer in a 2-way high-performance loudspeaker system, and the 8-ohm impedance makes it a natural choice for center channel MTM use as well.
