THE OPTIMUM SURROUND SPEAKER
The Vandersteen VSM-1 is an advanced surface-mount loudspeaker
optimized for the unique requirements of the rear channel positions
in a multi-channel audio/video system. It was developed and refined
by twenty years of intensive research into loudspeaker design
and multiple speaker integration. Its innovative engineering,
superior components and quality construction provide true high-fidelity
performance.
ALIGNED COAXIAL DESIGN
With stereo, imaging became part of home music reproduction. Today,
modern multi-channel systems can add the third dimension and create
an expansive, realistic soundfield. The way to do this in a large,
purpose built studio is with four identical full-range speakers
and a center speaker. Most homes however, do not have the room
to place the rear speakers where their drivers can fully converge
and properly align at the listening positions. Without this critical
alignment, the rear speakers will not match the time, phase or
amplitude of the front speakers. (i.e. timbre and voicing)
The VSM-1 is the optimum rear channel speaker for these situations.
Its coaxial woofer and tweeter share the same acoustical center
so they are always perfectly aligned and converge within inches.
When wall mounted in a typical living room, VSM-1s provide a superb
timbre and voice match to Vandersteen center and floor standing
speakers. They maintain this essential match regardless of their
placement or proximity to the listeners. Their immunity to multi-driver
interference insures consistent performance through the listening
environment.
APPLICATIONS:
In addition to perfectly complementing Vandersteen front speakers
in a matrixed multi-channel system, the VSM-1 joins the VCC-1
center speaker in exceeding all the requirements of the discrete
multi-channel formats (AC-3, DTS, etc.) Its innovative crossover
circuitry insures that it can safely handle the high-power, low-frequency
information the discrete formats send to the rear speakers. Its
front-firing, single driver configuration provides a high dynamic
range without the multi-driver interference and distortions of
bi-polar designs.
With its combination of convenience and performance, the VSM-1
can also be used as a high quality remote speaker in multi room
installations. Mated with the appropriate subwoofer, it is a superb
full-range main speaker for domestic situations where larger speakers
are not practical. In any situation, the VSM-1's moderate size
and versatile placement options allow it to be successfully integrated
into the decor of your home.
COMPONENTS:
The VSM-1 combines classic strength and durability with innovative
design and materials. Its coaxial driver uses a rigid, acoustically
inert cast-metal basket to improve cone movement accuracy and
reduce sympathetic resonances. The 6 1/2 inch woofer's filled
polycone insures high internal stiffness while the 1-inch alloy
dome tweeter is ferrofluid cooled to increase power handling and
critically damped for smooth response.
The transient-perfect, first-order crossover's computer-grade
components, including high-quality film capacitors in the signal
path, are hand soldered on a double-sided, plated-through circuit
board for superior consistency and reliability. The input block
is directly soldered onto the circuit board and the driver elements
are connected with custom high-purity wire for maximum signal
transfer.
The enclosure is constructed entirely of MDF, a pressure-formed
material that effectively resists vibration and controls cabinet
resonances. The unique mounting system uses the speaker's own
mass to hold it tight against the wall for proper coupling and
stability.
DRIVER:
Aligned coaxial design with a 6 1/2" die-cast basket polycone
woofer and a 1" critically-damped, alloy dome tweeter.
SPECIFICATIONS:
Even with advanced test equipment and complex computer analysis,
loudspeaker design remains an incomplete science. No measurements
currently available can fully convey the sound of a speaker or
provide a meaningful comparison between differing designs. The
truth is in the listening.
CROSSOVER:
3500Hz. 6dB per octave.
PHASE:
The woofer and tweeter are both in positive phase.
IMPEDANCE:
8 ohms nominal. 5 ohms minimum.
EFFICIENCY:
86dB at 1 meter with a 2.83 volt input.
RESPONSE:
60Hz to 21kHz 3dB
AMPLIFICATION:
30 to 100 watts per channel into 8 ohms.
CONTROL:
Treble contour control.
INPUT:
Heavy-duty terminal block.
MOUNTING:
On-wall at any height or lateral position. Wall brackets and hardware
are included with the speakers.
AVAILABLE FINISHES:
All standard Vandersteen finishes and grille colors plus new white
with perforated metal grille. The white end caps and metal grille
can be painted to match the speakers' surrounding.
See your dealer for custom finishes to match your existing furniture
or room decor.
WEIGHT:
31# net/each, 68# gross/pair.
WARRANTY:
One year, extendable to five years by registering the free optional
warranty within 30 days of purchase.
