Beak - Totem Rainmaker Manual

THE BEAK
The "Beak" was developed to control parasitic vibrations that occur on top of a speaker cabinet. These
resonances interfere with speaker performance, specifically the waveform symmetry emitted by
tweeters. Implementing a Beak on any speaker can effectively control and provide a better interaction
between speaker, tweeter and housing.
Careful thought and research were poured into the development of the Beak. Its precisely defined
contour was carefully designed; if any of its properties were altered, it would impact the flux created
within and render the unit ineffective.
The Shape
The "Beak" is milled in a prescribed form, which controls resonance
and directs emanation. These distortions occur within a strict range.
The Beak can channel common distortion and move it through its
cavity to the discharge point on top, hence its shape and name. As
the beak on a bird or whale channels sound, this Beak channels the
negative effects of dynamic speaker housings.
Mass and Detail
The mass of the Beak is crucial to proper holography and image
integration. In addition to the proper size and curve ratio, tests were
done to determine the texture on the surface of the Beak. The
spacing of the micro ribs increases from the bottom part to the peak.
In fact, the line structure (micro ribs) controls the velocity at which
the Beak dissipates distortion, helping the tweeter extend its range.
This surface texture helps alter frequency and phase, allowing you to
lock in a proper height and correct three-dimensional image.
Placement
The placement on smaller speakers is usually towards the outer front corner of a speaker pair. If one
looks at the top of the "Arro" (our smallest surface area speaker), the placement is up front toward the
outside. On larger speakers, a proper location must be derived. Experimentation is the key to
determining the proper location.
Specs
The high frequency difference when using the "Beak" is measurable
and quite apparent. The tweeter generally has better linearity in the
8 kHz to 20 kHz range. Therefore, better staging and imaging is
evident. At the crucial crossover point, frequency dips both on and
off axis can be alleviated by as much as 1.5dB. Outcome: better
harmony between woofer and tweeter, resulting in enhanced speed,
impact and transients.
