Product Details

ESS 689-1012 10" Cast Frame Woofer Speaker

Famous for the superb Air Motion Transformer mid/high transducer, ESS also manufactures woofers that match the AMT's quality and performance. The ESS 689-1012 10" woofer features a specially coated and reinforced paper cone with half-roll rubber surround, the combination of which provides a perfect balance of mass, rigidity, and good linear excursion capabilities.

A cast aluminum frame protects and aligns the woofer's critical moving components, as well as avoiding the diversion or dissipation of the 35 oz. ceramic magnet's high motor strength. Highly conductive and fatigue resistant woven tinsel leads establish a reliable connection between the high-power 1-1/2" copper voice coil and the oxidation resistant gold-plated input terminals.
