Dual JBL low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.
Improves high frequency performance as well as system reliability
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.
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 along with an attractive 18-gauge hexagon perforated steel grille to protect components from damage.
