Specifications &
Parameters
† 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 infinite
baffle 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 “infinite baffle” configuration. 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
midbass drivers.
