WEEK TO PRODUCE EACH CABINET |

Black Diamond is our moniker for a stunning new collection of contemporary
Audio/Home Theater speakers. Sophisticated, stylish and accurate audio
reproduction instruments, Pinnacle’s Black Diamonds are encased in a
lavish piano gloss finished cabinet. These beautiful speakers require 40
meticulous procedures and processes to attain their highly refined
appearance. In fact, it takes a full week to produce each cabinet. Nine
stages of coatings and polishing treatments culminate in an heirloom grade
exterior that’s certain to enhance any home décor.
But
just because they look terrific, let’s not forget their impressive sonic
attributes! Carefully chosen driver components meld through Pinnacle’s
expertly crafted crossover networks. The resultant sound is smooth,
powerful and spacious.

| SILK DOME TWEETER |
|
Pinnacle’s Black Diamond Series is
also notable for unique application of its specialized drive
elements. A highly refined silk dome tweeter is common to all
models. It features a modified domed horn (dhorn) loading
for efficient reproduction of the most sensitive nuances of the
program.
Powered by an ultra-compact neodymium (rare earth)
magnet, the tweeter is encased in the cabinet by a precision
pressure fit mounting system for a neat, clean look. Combined with
a magnetic liquid filled gap and incorporating resonance
suppression circuitry, the tweeter’s performance is as exemplary as it
is exhilarating.

| DIE
CAST PHASE PLUG |
|
The silver plated
zinc-magnesium die cast phase plug…It’s the most striking
visual feature of the Black Diamond Series 4" & 5 ¼” drivers. The
Die Cast Phase Plug improves the crossover function by suppressing
upper harmonic resonance nodes. The phase plug creates an
attractive “bullet like” appearance on the drivers. This selective frequency moderator functions mechanically and its
precise operation is geared to the streamlined form of the solid
casting.

SPECIAL FEATURES |

The phase plug midrange drivers are sealed off from the
rest of the system, enclosed in their own isolation chamber. This
enclosure enables the driver to extend its output level while maintaining a
high degree of clarity.
