Designed to serve as the front-center
loudspeaker in a multichannel surround-sound system,
the Resolution C, a 3-way design, features four drive
units: one tweeter, one midrange driver, and two woofers.
The drive units are configured for optimum horizontal
dispersion. The Resolution C is a dual port vented
cabinet housing two high excursion 8-inch woofers,
a 4-inch midrange, and the same tweeter used in the
Resolution 1.
Unique in the ability to provide extremely
detailed, high-powered reproduction for both music
and movie playback, the Krell Resolution Series features
robust MDF construction. The external enclosures are
1- inch in-wall thickness and the baffles are constructed
of a unique 2-inch thick sandwich that eliminates
baffle resonance. Midrange drivers are isolated within
internally braced sub-enclosures. The curvature of
the cabinets is designed to completely minimize the
effects of internal standing waves. Internal bracing
is aligned asymmetrically to increase cabinet rigidity
while further reducing internal resonant modes.
High Performance Crossover Networks
All network components are mounted on 1/8-inch thick
glass epoxy circuit boards with oversized 4-ounce
copper traces. This design ensures superior linearity
by minimizing circuit resistance and inductance. It
also eliminates microphonics and assures high current
handling capability. "Typical crossovers act
as funnels," described Mr. D'Agostino. "Power
delivered by the amplifier is choked off before it
reaches the drivers. The breadth and dimension of
the music is compressed by the crossover." Mr.
D'Agostino continues, "Our experience in designing
and manufacturing high power amplifiers is the underpinning
of our crossover design. The crossovers behave as
if they were extensions of our amplifiers, directing
the power to the drivers unimpeded."
Network inductors are all air-core
pure-copper designs; in the Resolution 1 the largest
of these is formed of 10-gauge wire, measuring 5 inches
in diameter. Multiple individually potted polypropylene
capacitors are employed in parallel to minimize resistance
and inductance while improving current handling.
In combination with the advanced drive
units, the Resolution crossover networks are engineered
to provide an extremely smooth impedance curve with
high efficiency. They, therefore, present a predictable,
nearly ideal load to the power amplifier.
