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.
