Description
The 1.75" PKX dome NDX595 is a compression driver for professional applications where high-quality sound and long-term reliability are required. The ultra-compact size and the low recommended crossover point at 1000 Hz make it ideal for small two-way cabinet designs and three-way loudspeaker systems. PKX (modified polyether ether ketone) is a rigid yet lightweight material, optimized with reinforcing ribs, offering remarkable precision and reliability compared with other polymeric materials. The voice coil utilizes ultralight edge wound aluminum wire, class-leading neodymium magnets, a 3-slot phase plug, and a copper ring design to deliver exceptional power handling, sensitivity, and low distortion across its operating bandwidth. The driver specifies 140 Watts of continuous power handling at 8 ohms, with a sensitivity of 110 dB.
