500 Watt Extreme Resolution Speaker System
EX10
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.

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-à-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.
EX10-VBRACKET
A vertical U-bracket designed for use with the top handle located M10 hang
point. The kit includes a special mounting plate with integral M10
attachment point that replaces the lower top hat assembly.
EX10-WBX 60.0
A black OmnimountTM bracket attaches to the top of the cabinet and allows
the cabinet to be vertically mounted.
