-
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 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 hexagon perforated, steel grille protects
components from damage.
|
-
Dual-angle pole-mount socket allows the speaker to tilt
10°for more uniform audience coverage.
