A proprietary harness simplifies
wiring and wire management
and increases sensitivity by
6dB, compared to wiring in
series.

INCLUSIVE MULTIUNIT WIRING ADAPTER
►
JBL Control NOW speakers eliminate
impedance restrictions with a wiring
adapter that makes configuring multi-unit
arrays simple.

adapters to wire the units for
two channels.
►
EVEN sound distribution – Use
this connection for even sound
distribution through both
channels. This may be more
appropriate for larger rooms.

ADVANCED TECHNOLOGY FOR A MORE NATURAL SOUND
HIGH-FREQUENCY TRANSDUCER WAVEGUIDE DESIGN.
►
JBL Control NOW speakers can go places
where other speakers cannot
►
Corner-mounting and some multi-unit
configurations would sometimes cause
unwanted sound reflections.
►
CONTROL NOW features an all-new adaptation
of JBL’s patented Bi-Radial® horn
JBL CONTROL NOW™
ADVANCED TECHNOLOGY FOR A MORE NATURAL SOUND
HIGH-FREQUENCY TRANSDUCER WAVEGUIDE DESIGN.
►
For JBL Control NOW speakers, a new Bi-Radial-horn profile with smoothly
blended edges was developed to minimize diffraction artifacts.
►
The result is remarkably
wide and uniform highfrequency response, which
is also exceptionally
smooth.
JBL CONTROL NOW™
ADVANCED TECHNOLOGY FOR A MORE NATURAL SOUND
HIGH-FREQUENCY TRANSDUCER WAVEGUIDE DESIGN.
►
Each JBL Control NOW tweeter uses 3/4" (19mm) titanium-laminate diaphragms
and ferrofluid-cooled voice coils driven by high-strength neodymium boron-iron
magnets.
►
It’s a high-efficiency design for
maximum power handling, minimal
thermal compression.
►
The tweeter/ Bi-Radial-horn
combination produces more than
100dB at 2kHz, from 2.83 volts at 1
meter.
JBL CONTROL NOW™
ADVANCED TECHNOLOGY FOR A MORE NATURAL SOUND
LOW-FREQUENCY TRANSDUCER DESIGN.
►
JBL Control NOW speakers’ low-frequency transducers deliver an ideal
combination of enhanced power handling and output, with reduced
distortion.
►
Low-frequency performance is
optimized through Finite Element
Analysis of transducer motor and
suspension components.

LOW-FREQUENCY TRANSDUCER DESIGN.
►
FINITE ELEMENT ANALYSIS (FEA) is a computer analysis technique using the
finite element method to break large, complex systems into small pieces (or
elements).
►
By breaking the complex system down
into small pieces, the system becomes
predictable, as each element is
solvable and the solution to the
system is simply the combination of all
the element solutions.

Optimized voice coil placement
maximizes heat transfer and provides
symmetrical motor force.
►
Optimized suspension

ADVANCED TECHNOLOGY FOR A MORE NATURAL SOUND
SYSTEM ACOUSTICAL DESIGN.
►
The frequency response of JBL Control NOW speakers is optimized for maximum
placement flexibility, particularly relative to walls, ceilings and corners.
►
CONTROL NOW have
constant-directivity
characteristics when wallmounted
►
and Omni-directional
characteristics when cornermounted or grouped in a fourspeaker circular array.

MECHANICAL DESIGN.
►
►
Enclosures and baffles are constructed of a thermoplastic composite material
containing both glass and mineral fill.
It’s exceptionally stiff, yet well damped, and enclosure walls are
double-thick (1/4").

A highly integrated mechanical design uses die-cast aluminum lock plates, port
tubes – and even the electrical network board itself
Increased rigidity and structural integrity to
further reduce unwanted resonances and
acoustical loss.
