Features
  • 4.5-inch Inside/Outside CCAW (copper-clad aluminum wire) voice coil
  • 3400 Watt continuous program power handling
  • 98.5 dB Sensitivity
  • 25 Hz - 1 kHz Frequency range
  • Hypervented magnetic structure for minimum power compression
  • Triple roll surround and exponential cone geometry
  • Single aluminum demodulation ring

The LN19S450 is a 19-inch extended low-frequency transducer designed with high excursion piston capabilities, perfect for vented enclosures where power and low-frequency extension are priorities. One of the key highlights of the transducer is its ultralight CCAW (copper-clad aluminum wire) voice coil, which is configured in a 4.5-inch, 4-layer inside-outside voice coil with fiberglass former material. The ultra-long excursion moving mass (67mm/2.6" safe peak-to-peak) with high power and fast acceleration capabilities. Employing a cone assembly loaded with fibers and featuring a generous triple-roll surround, the LN19S450 is engineered to decrease flux modulations and enhance transient response. The Hyper-Vented dual-forced air system enhances voice coil ventilation, effectively minimizing power compression.
