The new KV2 Audio EX12 High-Output
Active Full-Range Speaker made its NAMM Show debut in Anaheim this week.
Distributed in the United States by American Music & Sound (AM&S), the EX12
was developed at KV2's Milevsko, Czech Republic R&D facility and embodies
the company's philosophy of increased dynamic range, very high output, and
consistent sound character no matter what the output level.
The EX12's compression driver is a new, 3-inch titanium 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 according to the company. Each feature was developed over an extended period
of time and implemented as part of a strategy to lower distortion, increase
output and improve response characteristics.
The largest advancement was made in the development of a new treated
titanium material used in the dome assembly. Through Nitrate Vapor Particle
Deposition (VPD), an additional layer of material is fused to the titanium
at a molecular level. The resultant gold-colored material has dramatically
improved resonance characteristics and improved dampening resulting in lower
distortion artifacts and improved frequency response linearity, extending
the driver's response beyond 20kHz.
KV2 Audio has implemented trans-coil, a technology that eliminates voice
coil inductance, resulting in a flat impedance response above the resonance
point, achieving faster transient response through increased force and
control of the moving mass. This technology linearizes acoustic and
electrical phase response, reduces harmonic distortion and increases power
transfer and transducer speed. The speaker now behaves like a woofer at
lower frequencies and like a mid-range at higher frequencies allowing a
seamless transition at the crossover frequency.
A lot of power is required to achieve high output from a small cabinet.
Precisely selected amplifier topologies have been designed to deliver 500
watts of total power. A high current, high efficiency, low frequency
amplifier delivering 450 watts powers the low frequency driver. Heat
dissipation takes place through a unique "finless" heat sink that ensures
cool operation no matter how the speaker is positioned.
Capable of 127dB sustained output with very high dynamic range, the EX12
uses an asymmetrical, trapezoidal Baltic Birch cabinet design with
proprietary top and side handles. Each EX12 handle location feature an M10
hang point and full Omnimount compatibility. The cabinet has two M10
hang points on top and on bottom. Two additional side points provide
versatile installation flexibility using available brackets. A touring
version featuring recessed fly-track, the EX12t, is also available.
The EX12 is now shipping and has a suggested retail price of US $2499.
