Congratulations!
You have purchased a high quality stereo
loudspeaker. When matched to comparable electronic
equipment, expect years of quality high fidelity sound. Our
belief is that music matters and we are focused on delivering
superlative music reproduction everywhere in your home.
The following manual is designed to give you, the installer or
owner, basic information as to the speaker’s installation and
operation. It is beyond the scope of this manual to go into all the
details that must be taken into consideration in a sophisticated
high fidelity system. When installing the wiring and speakers it is
important to adhere to all local codes and regulations. Consulting
a professional will help to maximize your system’s performance.
If you have any questions that are not answered by this manual,
contact your local dealer for assistance. For the most current
information please visit: www.preference-audio.com.
SHIPPING DAMAGE
Each speaker is thoroughly tested before it leaves the factory.
However, in shipment, accidents may occur. Please inspect your
speakers carefully when you receive them to make sure there
is no damage. If there is, please notify your dealer, or supplier
immediately for assistance. If you received your speakers by
public transportation, report the damage at once to the shipping
company.
AMPLIFIER OPERATION
These speakers will perform well with amplifiers from 5 to 125
Watts RMS. However, damage to the speakers can be done by
amplifiers of nearly any power rating if the amplifier is overdriven
into clipping. “Amplifier clipping” is a phrase used to describe
a condition when, because of the volume demand, an amplifier
is being asked for more power than it can give. Clipping causes
distortion of the audio signal. If you should hear an unusual
amount of distortion at high listening levels then consider
reducing the volume. DAMAGE DONE TO A SPEAKER BY CLIPPING
IS NOT COVERED UNDER THE WARRANTY.
HOW IS THIS SPEAkER DIFFERENT?
This speaker was designed and engineered to provide the finest
performance achievable in a compact package. The custom
waveguide is unique in the industry and provides cross-axis
performance that gives every listener in the room a sense of
envelopment unmatched by other speakers in this category.
By focusing the sound field across the listening space, the
listener experiences a more balanced and symmetric sound level,
especially when the main speakers are spaced more closely than
is ideal, (common in many of today’s home theaters).
The waveguide also increases the efficiency of the tweeter,
allowing it to operate with far less input power and significantly
lowering the distortion. This also
allows for the elimination of the
ferro-fluid used for heat dissipation,
improving elements of the tweeter’s
performance including part-to-part
consistency. This same waveguide
also allows the tweeter to operate a
full octave lower than conventional
dome tweeters while simultaneously
reaching more than a half octave
higher in frequency. This allows the
tweeter to cover more of the critical
voice range.
But we’re not done yet. This same
cross-axis tweeter design creates
a much smoother off-axis listening
experience, eliminating the midrange-
hole that is commonly experienced
with conventional designs. Additionally, by controlling the
directivity of the sound field, the early reflections that occur from
nearby walls and furniture are reduced so that more of the direct
sound from the speakers are heard, improving the intelligibility
and detail of the original sound source.
Finally, the inset tweeter produces a time aligned position and
excellent phase coherency with the woofer, improving the off-axis
performance, both in the vertical and horizontal directions.
WOOFER
While the tweeter has allowed us to create a truly unique speaker,
the woofer’s complement of components provides the balance of
performance. Every detail of the woofer was considered using a
“Design of Experiments” methodology:
•
Cast aluminum basket with its stiff but inert structure
•
Super-light extra-long copper-clad aluminum voice coil
•
Low eddy-loss mechanically damped Kapton former
•
Lightweight curved woven cone made from genuine Dupont Kevlar
®
•
Linear-transitioning butyl rubber surround
•
Vibration damping silica rubber motor boot
•
High compliance flat spider
•
Machined aluminum heat-dissipating phase plug
Clearly, care was exercised to create a woofer that behaves as well
off-axis as it does on-axis and meets the tweeter’s top caliber
performance.
CROSSOvER
Of course all of this performance is brought together using a
sophisticated multi-order crossover that seamlessly blends the
drivers for performance that rivals and exceeds everything in
its class. The crossover contains two level controls to tailor the
speaker for the application.
CONTROL ADjuSTMENT
There are 2 switches located on the front baffle, labeled MF and
HF, (Mid-Frequency and High-Frequency, respectively). Each
switch has 3 positions that allow the user to tailor the sound of
the speaker for different room acoustics, mounting locations,
and personal preference. These controls are also useful when
using the speakers behind acoustically transparent video screens
(where some augmentation of the upper frequencies may be
necessary) or when customizing the speakers for unique surround
applications where the sound may be either focused directly at
the seating area or reflected off nearby surfaces. The diagrams
below show an approximation of how each control affects the
frequency response. Moving the switches up () increases
the output.
The Mid-Frequency (MF) control allows for a relaxed, neutral, or
forward midrange presence.
The High-Frequency (HF) control affects the uppermost audible
range to create soft, neutral, or articulate detail.
PAINTING THE GRILLE
The grilles can be painted using multiple light coats of spray paint.
Custom color spray paints are available from specialty companies.
Contact your dealer for more information. The grilles should be
removed from the speaker and painted in a clean environment to
prevent contamination. It is best to go around the grilles and apply
the paint from multiple angles. DO NOT remove the scrim cloth
from the backside of the grille. It is not replaceable.
Attach the grilles to the speakers and enjoy. Should you wish
to remove the grilles from the speakers pull at the grilles' edge.
Initially there will be significant resistance because the grilles are
magnetically attached.
