18LW2600

Features

  • 97 dB SPL 1W / 1m average sensitivity
  • 100 mm (4 in) Interleaved Sandwich Voice coil (ISV)
  • 3000W program power handling
  • 60 mm peak to peak excursion
  • Single Demodulating Ring (SDR) for lower distortion
  • Composite reinforced straight ribbed cone
  • Recommended for subwoofer usage in compact vented enclosures
The 18NLW4100 is a 18" (466 mm) ultra light extended low frequency loudspeaker,especially designed for use in vented enclosures. The loudspeaker is designed to withstand high power levels without damage while providing clean and undistorted LF reproduction at a very high SPL. For optimum results we recommend amplifiers able to deliver 3000 Watt program power. The 18NLW4100 features a unique motor featuring a high grade Neo magnet assembly in a structure optimized for thermal and magnetic efficiency. 18NLW4100 features include a large displacement suspension system which, in conjunction with a composite reinforced, straight ribbed cone, allows an ultra-linear piston action and provides full mechanical control across the entire working range. The 100mm (4 in) state-of-theart voice-coil utilizing Interleaved Sandwich Voice coil (ISV) technology, provides high levels of thermal stability and durability. The ISV technology achieves a balanced linear motor unit exerting an exceptionally high force factor.
