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 EX12’s 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 compression driver is a new,3.00-inch ti-
tanium diaphragm design, featuring a radial
phase plug,progressive parabolic semi-circle
suspension,direct-drive nomex voice coil assembly
and the industry ’s largest neodymium magnetic motor
structure.Each feature was developed over an ex-
tended period of time and implemented as part of a
strategy to lower distortion,increase output and improve
response characteristics.
The EX12 horn was designed with one primary perfor -
mance goal. The horn design is based on constant- di-
rectivity geometry with an emphasis on generating very
low air distortion artifacts, maintaining low transducer
compression ratios, high output and wide dispersion
(80 x 40). The horn is an injected molded aluminum
part that functions as a heat dissipater for the compres-
sion driver’s neodymium magnetic motor structure.
Enclosure Design
The EX12 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 EX12 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 EX12 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 EX12.
AC POWER
The EX12 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 EX12 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.
