The high-per
essive sound usually associated only with much lar
mance VRC is a timbre-matched center channel speaker that is a perfect compliment to any of the VR floorstanding
for
models in your home theater system. The VRC’s three-way design delivers extremely wide horizontal dispersion and exceptionally
high power handling capability.
All three VR floorstanding models feature dual woofers for deep, authoritative bass response and low distortion. The placement
of the woofers on the baffle has been chosen with extreme care and precision, and it provides two very specific, clearly audible
benefits: First, by separating the woofers by a precisely calculated distance, the internal "pipe organ" standing wave—common

es that have their bass drivers closely gr
esult is less midrange coloration and a commensurate incr
ouped at one end of the cabinet—is reduced to the point
ease in clarity and detail.
The second benefit is smoother, more uniform upper bass/lower midrange frequency response in a real listening room.
The dimensional r
elationship of the woofer to the nearby room boundaries (the walls and floor) in any speaker results in
a reinforcement or cancellation of upper bass/lower midrange frequencies corresponding to the woofer-to-boundary distances. By placing the cabinet’s two woofers at optimally chosen different locations, these dimensions are "averaged" over
a wider variety of distances, ther
eby reducing the influence of any single woofer-to-boundary dimension. The result is much
smoother, more accurate in-room frequency response, with far less of the typical "peak and dip" characteristic found in
conventional designs.
The 3-way models utilize a newly-developed 4
1
⁄2-inch (115mm) midrange driver with a large 11⁄2-inch voice coil for superb
driver control and extremely high power handling. Its powerful neodymium magnet produces 10 times more magnetic
energy than a conventional magnet of the same size, but its compact dimensions allow the tweeter and midrange to be
mounted very close together for seamless, perfectly integrated sound with wide, uniform dispersion. A high output 1-inch
(25mm) anodized aluminum VR tweeter, with our exclusive patented Amplitude Modification Device (AMD) produces extended, sparkling high frequencies.
The cabinets have extensive internal bracing and are constructed of Medium Density Fiberboard (MDF), chosen for its favorable acoustic characteristics. The result is superb structural integrity that eliminates the spurious resonances and vibration
that degrade the sound of ordinary speakers.

How to Connect Your Speakers
Correctly wiring your speakers is important for achieving the best sound quality. Wiring should take just a few
minutes, but it’s important to do it carefully, since incorrect wiring (such as reversed connections) can result in a poor
soundstage and poor bass.
We recommend 18-gauge wire or thicker for runs up to 25 feet (8m), and 16-gauge wire or thicker for longer runs.
Separate the first few inches of the wire conductors. Strip off
1
⁄2" (12mm) of insulation from the ends of each speaker
wire to expose the two conductors and tightly twist the wire strands.
When making all connections, be sure to connect the
+ (red) on the speaker to the + (red) on the amplifier, and the –
(black) on the speaker to the – (black) on the amplifier.
WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections
to the speaker.
IMPORTANT: Typically, one side of the wire is smooth.
Connect this side to the
– (black) connection. The
other side has a rib or stripe. Connect this to the
+ (red) connection.
Using the five-way binding posts: The binding posts
mit easy connection to banana plugs, spade lugs,
per
and bare wire.
Insert the wire in the hole and tighten.
