Features : Specifications :

* 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 Transitionâ„¢ 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.

* SonicGuardâ„¢ 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.
