• 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.
• 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.
• 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' 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 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.
