Features : Specifications :

* 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.

* 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.

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

* Progressive Transitionâ„¢ 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.

* SonicGuardâ„¢ protects the highfrequency 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.
