About the ESS amt-1b
The ESS amt-1b is a classic floor-standing loudspeaker system renowned for its use of the Heil Air Motion Transformer (AMT) tweeter, which delivers exceptional clarity and low distortion. The system features a 305mm (12-inch) bextrene cone woofer and a matching 305mm passive radiator for extended bass response. The AMT tweeter operates by compressing air through Teflon accordion pleats in a strong magnetic field, resulting in high efficiency and excellent damping. The cabinet is finished in walnut veneer and features a robust, rigid construction for superior acoustic performance.
