JRX-118SP

18" Powered Portable Subwoofer

New

For those who prefer the simplicity of a self-powered subwoofer, there's the JRX118SP. JBL started with the same woofer used in the non-powered JRX118S and added a specially designed amplifier with 500 watts (peak) and 300 watts (continuous) power output. 

  • Dual JBL low frequency drivers with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more crosssectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.
  • Ferro-fluid cooled compression driver with titanium diaphragm improves high frequency performance as well as system reliability.
  • The advanced network topology crossover design shapes frequency response and delivers coherent summation in the crossover region.
  • A "Quasi 3-Way" design offers the extra bass for which a dual fifteen system is designed, but without sacrificing performance in the critical mid-range. The upper woofer produces mid-frequencies and bass, while the lower woofer concentrates on bass only. The reduction in mid-range phase cancellation greatly improves midrange sound quality and coverage.
  • High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.
  • Progressive Transition™ highfrequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response.
  • The rugged, acoustically superior enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance.
  • SonicGuard™ protects the highfrequency driver from excess power without interrupting the performance.
  • Non-resonant, all-steel handles are used.
  • Attractive 18-gauge perforated, steel grille protects components from damage
