KV2 Audio EX10 - Manual (Page 4)

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 in-
ductance 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 in-
creases 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 EX10’s patent pending neodymium compression
driver is loaded on a constant directivity horn designed
for smooth, wide dispersion performance. More impor-
tantly, it has also been designed to precisely match the
power response of the woofer at the crossover fre-
quency, a crucial design objective that ensures smooth
transition and minimizes anomalies.
The compression driver is a new, patent pending 1.75-
inch titanium diaphragm design, featuring a complex
geometry phase plug that dramatically lowers distor-
tion, eliminates ring modes and provides clearer, ripple
free performance.
The EX10 horn was designed with two primary perfor-
mance goals. The mechanical design allows the horn
to be rotated 90 degrees, allowing for complete flex-
ibility in selection of vertical and horizontal system set
up. The horn design is based on constant- directivity
geometry with an emphasis on generating very low air
distortion artifacts, maintaining low transducer com-
pression ratios, high output and wide dispersion (100
x 80). The horn is an injected molded aluminum part
that functions as a heat dissipater for the compression
driver’s neodymium magnetic motor structure.
Enclosure Design
The EX10 is a very compact, asymmetrical geometry
enclosure design allowing it to be used in a variety of
applications and featuring a number of ergonomically
designed components that make it lightweight and easy
to use. An extensive set of professional hardware fea-
tures enables the EX10 to be used in a variety of envi-
ronments using an array of industry standard hardware.
These facilitate both portable and fixed installations
with a maximum amount of mounting flexibility.
A specially molded aluminum top handle was designed
and fitted to the top of the cabinet. It functions as the
principle pick up handle as well as providing several
fixed installation and hanging solutions. It has a cen-
trally located M10 hang point as well as four additional
M6 bracket points. The handles four principal mount-
ing bolts also provide an Omnimount™ bracket point.
There are two side-mounted M10 hang points that can
be used with brackets or eyebolts.
APPLICATIONS
• Live and Playback Applications
• Portable PA Systems
• Floor Monitoring Applications
• Corporate Events
• Fixed Installations
The EX 10 is an advanced self-powered loudspeaker
system with on-board amplification and control sys-
tems. Understanding power distribution, voltage and
current requirements, as well as electrical safety is-
sues, is critical to the safe operation of the EX10.
AC POWER
The EX10 uses a PowerCon 3-pole AC main system
with locking connectors to prevent accidental discon-
nection. The main AC connector (blue) serves as the
power input.
The EX10 operates in either 115V, 230V or 250V modes.
Although pre-configured at the factory, the unit’s operating
voltage mode can be changed in the field.
