{"product_id":"cdk455","title":"RCF CDK455 Driver","description":"\u003cp\u003eThe CDK455 is a compression driver for professional applications where high-quality sound and long-term reliability are required. The ultra-compact size, 1.75\" Kapton® dome, and the low recommended crossover point make this transducer ideal for point source two-way cabinet designs. The new 1.75\" compression driver voice-coil design with Polyimide-Kapton dome features a new bonding technology and reinforced ribs make it robust and durable. The transducer utilizes ceramic magnets and a 2-slot phase plug to deliver exceptional power handling, sensitivity, and low distortion across its operating bandwidth. The driver specifies 140 Watts of continuous power handling, with a sensitivity of 109 dB.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1.75-inch Kapton\/polyimide dome\u003c\/li\u003e\n\u003cli\u003eKapton former, edge wound aluminum voice coil\u003c\/li\u003e\n\u003cli\u003e140W continuous program power handling @ 8O\u003c\/li\u003e\n\u003cli\u003eFrequency range: 1200Hz -
