JBL JRX212D ตู้ลำโพง 12 inch, 2 way speaker system

 

  • JBL 12 in low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.

  • JBL 2414H-C 25 mm (1 in) polymer diaphragm compression driver 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.

  • High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating.

  • Progressive Transition™ high frequency 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 high frequency driver from excess power without interrupting the performance.

  • Non-resonant, all-steel handles are used.

  • Attractive 18-gauge hexagon perforated, steel grille protects components from damage.

  • Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage.
