Speaker development is our passion!
When installed and set-up properly,
the Clarus Component System
you have purchased will make a
remarkable improvement in the
sound quality of virtually any mobile
audio sound system and give years of
superior performance.
With the publication of this manual, it
is our goal to assist the “do it yourself”
enthusiast and professional installer
alike in getting the highest level of
performance out of Clarus Component
Systems using straight-forward
installation advice.
Your Clarus system
contains speaker drivers
and passive crossover
networks that were
developed and assembled
with a signicant
eort in research and
development, materials
science engineering,
an exhaustive level of
sampling and prototyping,
real-world testing, and
obsessive attention to
detail. The specications
and parameters of your
Clarus component system
is detailed on these pages.
Midbass Attributes
Clarus C5 & C6
Frame
Cast aluminum with black powder-texture surface
coating. The basket is a high-quality cast aluminum
design, which plays a critical role in aligning the
voice coil in the magnetic circuit. Additionally, the
cast aluminum frame allows for better clamping
strength verses typical stamped steel frames, and
ensures that the voice coil remains centered in the
former. The black coating on the frame protects
it from abrasion and oxidation. The frames are
similar in size and format to the Mirus, Imagine, and
Clarus-series drivers, allowing for upgrade potential
from these product lines to the Clarus series.
Cone and Dust Cap
Pressed paper, untreated on the front side
and treated on the rearward side. It is widely
acknowledged that pressed paper cones are the
best marriage of lightness, stiness, and ability
of the cone to damp unwanted cone and edge
modes and resonances (read: distortion). The
damping aorded by the paper cone ensures the
midbass speakers can play lower treble frequencies
eortlessly, without signicant cone “breakup.” Our
approach to “point-source imaging” is to rely on the
midbass driver to eectively reproduce the lower
treble frequencies, where the human vocal range
extends, as well as other imaging-critical musical
instruments, ensuring phase-coherent imaging and
stable, lifelike staging character.
The paper cone, known for its excellent sonic
attributes, is water resistant, thanks to a polymer
developed exclusive and proprietarily by Hybrid
Audio Technologies. The treatment does not
change the look and parameters of the driver like
old-fashioned “glossy” polymers which added
an appreciable amount of moving mass and
signicantly colored the sound. No, the Clarus cones
look like any “normal” paper cone. The treatment
protects the cone from periodic drips (such as inside
a door panel), as well as accidental splashes to the
front of the cone.
The dustcap covers the voice coil to keep dirt and
debris from fouling the voice coil gap. Since high
frequency information emanates from the center
of the cone, a paper dustcap was utilized in concert
with the pressed paper cone diaphragm to ensure
that the speaker’s response remained linear into the
lower- to mid-treble frequencies.
Surround
Inverted high-loss rubber surround. The inverted
high-loss rubber surround (in concert with the
spider, detailed below), helps to provide the
compliance and “restorative force” needed for the
Clarus drivers to play eectively into the lower
midbass, and even upper subbass frequencies
(depending on in-car cabin gain and other factors).
You’ll also know a Hybrid Audio midrange and
midbass design by its inverted surround; this
design feature allows for the use of a smaller height
grille, better clearance with OEM panels, and more
exibility in mounting options. The surround is a
shared technology with the Imagine series coaxial
and convertible component sets.
Spider
Phenolic fabric and tinned tinsel leads. The spider
is the brownish/yellow corrugated (rippled) fabric
that attaches the cone and voice coil. The spider for
the Clarus designs was the subject of a considerable
amount of our research and development. The
spider is a phenolic symmetrically-rolled fabric
which provides excellent restorative force during
excursion, and the woven tinsel leads, often not
found in speakers in this price range, are an asset to
the Clarus line because the leads are protected from
physical damage and accidental short circuit. The
tinsel leads are connected to real epoxy PCB, not
imsy cardboard.
Voice Coil and Motor System
1” (25mm) (C5) and 1.4” (35mm) (C6): complimentary
design. The voice coil used in the Clarus midbass is
a 2-layer aluminized copper wire coils on a round
former. An “overhung” voice coil was selected to
improve sensitivity while still keeping distortion
to a minimum. The motor system utilizes a ferrite
magnet with rubber protective boot (which
can be removed to improve mounting depth),
complimented by design with a back plate and
rear venting chamber to improve the speaker’s
thermal power handling and improved ability of the
midbass to play at high amplitudes.

Tweeter Attributes
Clarus C1
Dome
Small diameter impregnated silk textile dome
with high-loss rubber suspension. The C1 is
a shared technology with the high-end Unity
U1 tweeter, boasting has an impregnated ne
cloth silk dome diaphragm for a linear, smooth
sound, with a high-loss rubber suspension
to damp edge modes and resonances. The
dome is of extremely low mass and is much
less susceptible to mechanical deformation
than other designs, and yet yields a smooth
response over the extent of its range. At Hybrid
Audio Technologies, we feel larger diaphragm
tweeters sound heavy and unremarkable,
lack detail in the upper treble frequencies,
have undesirable polar response, and are
dicult to install. Additionally, we nd metal
dome tweeters to be harsh, brittle, and sound
unrealistic. As a small diameter, soft-dome
tweeter, the C1 is the antithesis of large
diaphragm and metal-dome tweeters, for the
eective and convincing reproduction of treble
frequencies.
Voice Coil and Motor System
20mm complimentary design. The motor
assembly is “conventional dynamic”, with a
ensure a small footprint size and shallow
depth. A perforated grille protects the dome.
The voice coil is ferrouid cooled and damped,
and the tweeter housing consists of extruded
plastic with three dierent mounting options
in component set mode, giving the end-user
exibility in not only placement of the C1 but
also in physical installation.
Crossover Attributes
Clarus C2x
Alignment
Second order L/R (12 dB/octave) lters for low
pass (C5 or C6) and high pass (C1). The C51-2
2-way passive crossover network includes
a Clarus low pass and high pass crossover
frequency of 5,700 Hz at 12 dB/octave. The
C61-2 2-way passive crossover network includes
a Clarus low pass and high pass crossover
frequency of 5,200 Hz at 12 dB/octave. The use
of 12 dB/octave lters on both low pass and
high pass, often not found in speakers in this
price range, minimizes phase-related distortion
typical of crossovers with mismatched orders,
and ensures phase-coherent imaging and
staging. The alignment topology is a shared
technology to the high-end Unity U2x crossover
design and features asymmetrically-aligned
network components.
Network Components
Audiophile grade. The C51-2 and C61-2
passive crossover networks incorporate super
high quality and low tolerance metalized
polypropylene lm capacitors for both highpass
and low pass, in concert with air-core inductors,
and low tolerance non-inductive resistors. No
output level switches were used in the passive
crossover design because switches add a
resistive eect and are typically of extremely
low quality. Additionally, “jumper pins” add
an unnecessary pair of splices in the signal
path to the tweeter, and were not included
in our design either. Rather, all tweeter level
adjustments are done on the board level with
dedicated non-inductive resistors; tweeter
attenuation is accomplished by selecting the
appropriate output (-3 dB, 0 dB, or +3 dB)
on the passive crossover circuit board. The
components selected are complimentary and
ensure no notable signal degradation between
the input and output side of the crossovers,
and serve only to lter frequency response,
and not to equalize the input signal. The
network componentry, design, circuitry, and
polyethylene case with transparent cover are
shared technologies to the Unity series, and the
Unity U2x crossover design.
† Typically, in-car response including vehicular “cabin gain”, or the gain expected
with midbass installed in the vehicle, will result in an extended midbass and
upper subbass response. This is a result of these frequencies being below the
lowest resonance in the vehicle (typically around 50-125 Hz in most vehicles,
described in more detail on pages 30 and 31). In more practical terms, install
the Clarus midbass into your vehicle and you will see a dramatic improvement
in midbass and upper subbass output, much more so than just simply listening
to the Clarus in a large room, or worse yet, “free air” (we don’t recommend even
trying the Clarus speakers in “free air” without some form of enclosure or innite
bae for the midbass).
Thiele/Small Parameter Discussion for Clarus Midbass
Speakers
The mechanical and electrical parameters of the Clarus midbass speakers
are amenable to a variety of different installations and speaker locations.
The high Qms (Q factor of mechanical system) and Qts (Q factor of total
system), coupled with the driver’s Fs (resonance frequency) allow it to be
used in an “innite bafe” conguration. In more practical terms, install
the Clarus midbass such that the front and back waves don’t “meet” (as
detailed in Section I – Getting Started - Basic System Installation), including
in a door or kick panel, or in the case of a motorcycle, in the fairing (using
only the airspace behind the speaker as a pseudo enclosure), with no
need for a real enclosure or “box.” The design goes hand in hand with
fool-proof, high-end sound quality with minimal work. For more advanced
users, please reference the Thiele/Small Parameters for the Clarus-series
