Your Clarus system
contains speaker drivers
and passive crossover
networks that were
developed and assembled
with a significant
effort in research and
development, materials
science engineering,
an exhaustive level of
sampling and prototyping,
real-world testing, and
obsessive attention to
detail. The specifications
and parameters of your
Clarus component system
is detailed on these pages.

Tweeter Attributes

Imagine I1

Dome

Small diameter impregnated silk textile dome
with high-loss rubber suspension. The I1 has
an impregnated fine 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 difficult to install. Additionally, we
find metal dome tweeters to be harsh, brittle,
and sound unrealistic. As a small diameter,
soft-dome tweeter, the I1 is the antithesis of
large diaphragm and metal-dome tweeters, for
the effective and convincing reproduction of
treble frequencies.

Voice Coil and Motor System

25mm complimentary design. The motor
assembly is “conventional dynamic”, with a
compact neodymium magnet structure to
ensure a small footprint size and shallow

depth. A perforated grille protects the dome.
The voice coil is ferrofluid cooled and damped,
and the tweeter housing consists of extruded
plastic with three different mounting options
in component set mode, giving the end-user
flexibility in not only placement of the I1 but
also in physical installation.

Tweeter Passive Crossover

Low-Tolerance Mylar Capacitor. The tweeter’s
protection circuit and crossover filter is a very
high-quality, low-tolerance Mylar capacitor
that has been affixed to the midbass frame. An
outboard crossover “box” is not included for
empirical reasons, explained here:

The set ships as a coaxial, and is ready to
install. Should the end-user want to connect
the tweeter in component set mode, simply
unscrew the tweeter, remotely mount the
tweeter, and extend wiring back to the midbass
terminals for re-connection to the tweeter
output posts. Refer to

pages 26 and 27

component set, as well as view an informational

Thiele/Small Parameter Discussion for
Imagine Midbass Speakers

The mechanical and electrical parameters of
the Imagine 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 “infinite
baffle” configuration. In more practical terms,
install the Imagine 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.”
