Acoustic Components
KV2 Audio has developed a revolutionary
woofer technology called Trans-Coil™. The
woofer has two coils, a standard voice coil
assembly and a second coil placed directly on
the neodymium magnetic circuit’s pole piece.
This technology eliminates voice coil inductance
resulting in a flat impedance response above
the resonance point and achieves faster transient
response through increased force and control
of the moving mass. It also linearises acoustic
and electrical phase response, reduces harmonic
distortion and increases power transfer and
transducer speed. Through this technology,
the speaker now behaves like both a woofer
at lower frequencies and like a mid-range at
higher frequencies allowing a seamless transition
to take place at the crossover frequency.
The EX6’s patent pending NVPD neodymium
compression driver is loaded on a constant
directivity horn designed for smooth, wide
dispersion performance. More importantly,
it has also been designed to precisely match
the power response of the woofer at the
crossover frequency, a crucial design objective
that ensures smooth transition and minimizes
anomalies.
The EX6 horn design is based on constant-
directivity geometry with an emphasis on
generating very low air distortion artifacts,
maintaining low transducer compression ratios,
high output and wide dispersion (100˚ x 100˚).
Introducing the EX6
The EX6 is a 2-way high output, active,
compact, full-range speaker system. Design
objectives for the EX6 were focused on the
expansion of KV2 Audio’s primary philosophy
of speakers systems with increased dynamic
range, very high output and a consistent
sound character no matter what the output
level. The EX6 sets new levels of performance
for compact cabinets achieved through the
integration of new amplifier, transducer and
electronic control technologies that are closely
tied to a passion for taking performance to
the next level.
Electronics
Amplifier power, electronic crossovers, phase
alignment, equalisation and speaker protection
are integrated into the EX6’s amplifier module.
The EX6’s high frequency compression driver
is powered and controlled by KV2 Audio’s
standard low intermodulation distortion,
Class A/B, push-pull, designed to produce the
lowest intermodulation distortion possible and
the highest audio quality in the critical mid
and high operating bands.
An improved version of KV2 Audio’s current
enhancing, Bass driver switching amplifier has
been developed for the EX6. The new configu-
ration improves overall system efficiency and
increases output allowing passive radiation of
heat to take place through a unique “fin-less”
heat sink that can be placed in any position or
direction. Additionally, the EX6 amplifier unit
contains an internally located electric fan that is
operated by a temperature sensing circuit
which will slowly bring the fan online as required.
The horn is an injected molded aluminium
part that functions as a heat dissipater for the
compression driver’s neodymium magnetic
motor structure.
