15"/1.4" Coaxial Speaker, 650/90W, 101/110dB, 40-20000Hz, X-max 5.5mm, Radiation angle 60°, Weight 6.5kg The CX15N351 is engineered to deliver exceptional frequency response linearity with minimal distortion. This coaxial speaker utilizes a robust neodymium magnetic structure that ensures high dynamic range and sensitivity for both components. The mid-bass section features a 3.5” voice coil design that offers superior power handling, outperforming standard 3" voice coils. The compression driver boasts a 2.5-inch diaphragm with a 1.4-inch throat, incorporating cutting-edge technologies. The diaphragm and suspension are crafted from 0.05mm thick pure titanium. The innovative magnetic structure enables a single point source, delivering a coherent wavefront.
