Beschrijving

500 Watt Extreme Resolution Speaker System

The
EX10 is a 2-way high output, active, compact, full-range speaker
system. EX10 design objectives focused on the expansion of KV2 Audio?s
primary philosophy of increased dynamic range, very high output and a
consistent sound character no matter what the output level. The EX10
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 KV2?s passion for taking
performance to a higher level.

Electronics

Amplifier power, electronic crossovers, phase alignment, equalization,
time correction and speaker protection are integrated into the EX10?s
amplifier module. On-board electronics ensure fast, easy set up and
complete control.

An
improved version of KV2 Audio?s Switch Mode, current enhancing low
frequency amplifier has been developed for the EX10. The new
configuration 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.
This ensures cool operation in horizontal or vertical applications.

Additionally,
the EX10 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 in extreme, high temperature
situations.

Months of research
were invested into designing circuitry to ensure that the EX10?s
extreme dynamic range is maintained even under clipping conditions. The
real test of the EX10?s limits is when it is exposed to the rigors and
demands of live audio playback where clipping of amplifiers, generation
of distortion artifacts and dramatic increases in the noise floor are
all par for the course.

Acoustic Components
The EX10?s high frequency compression driver is tightly controlled by
KV2 Audio?s standard low intermodulation distortion, Class A/B,
push-pull, high and mid frequency amplifier design. Metal Oxide Silicon
Field Effect Transistors (MOSFET) are used for the output stage; the
compression driver is coupled through a transformer balanced speaker
output. The entire performance strategy for this type of design is
based on producing the lowest intermodulation distortion possible and
the highest audio quality in the critical mid and high operating bands.

A
new woofer technology was developed in conjunction with the engineering
team at KV2 Audio?s transducer partner, 18 Sound in Cavriago, Italy.
The technology is called Active Impedance Control (AIC) and it delivers
several exciting performance advantages. AIC technology consists of a
carefully designed and placed ?additional? coil placed on the
speakers?s magnetic pole piece and connected in parallel to the primary
voice coil. The magnetic field generated by this additional coil has
the following effects:

1) Complete linearization of speaker impedance
2) Linearization of the acoustic and electrical phase response
3) Delivery of a significant increase in sensitivity and total SPL output
4) A remarkable reduction of Total Harmonic Distortion (THD)
5) Increased power transfer and transducer speed

All
of these benefits help minimize several weaknesses inherit in two-way
loudspeaker systems such as poor quality low-mids and weak transient
response found in this band pass. The EX10 is transparent, up-front and
seamless in comparison to any and all competitive active 10-inch 2-way
designs.

The compression
driver is a new, patent pending 1.75-inch titanium diaphragm design,
featuring a complex geometry phase plug that dramatically lowers
distortion, eliminates ring modes and provides clearer, ripple free
performance.

The EX10
horn design was designed with two primary design goals. First to be as
smooth as possible within its operating bandwidth and second to display
perfect power response characteristics vis-?-vis the 10-inch woofer it
is designed to crossover with.
The mechanical design allows the
horn to be rotated 90 degrees, allowing for complete flexibility 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
compression ratios, high output and wide dispersion (100 x 80). The
horn is an injected molded aluminum part that functions as a heat
dissipator 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 features
enables the EX10 to be used in a variety of environments 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
centrally located M10 hang point as well as four additional M6 bracket
points. The handles four principal mounting bolts also provide an
OmnimountTM bracket point. There are two side-mounted M10 hang points
that can be used with brackets or eyebolts.

There
are four industry standard, steel ?fly-clip? points. Two on top and two
located on the bottom of the cabinet. A side recessed, slot handle
provides a stabilization point as the cabinet is pole mounted. (The
EX10 is also available without these two features for applications
where flying is not required)

Accessories

EX2.2 Active Bass Module
The EX10 can be combined with an EX2.2 Active Bass Module in order to
create a formidable, very high output audio system. The EX2.2 is
comprised of two 12-inch woofers and features on-board amplification
and control electronics with 1000 watts of total power.

EX10-HBRACKET

A horizontal U-bracket designed for use with the two side-mounted M10 hang points.

hang point. The kit includes a special mounting plate with integral M10
attachment point that replaces the lower top hat assembly.
