TUKAN LOUDSPEAKER
Similar to the Majik Amplifier, the concept of a universal component with exceptional flexibility was
also the spark behind the Linn Tukan loudspeaker. Small enough to suit any environment, the
Tukan offers extraordinary performance and can be easily reconfigured for different modes of
operation as your requirements change.
Applications
Offering clarity of reproduction that belies its small dimensions, the Tukan is ideal for any
application where space is at a premium. It is suitable for use on stands, wall mounts (mounting
points for optional wall-brackets are fitted as standard), or bookshelves.
When used as the primary speakers in a high-quality audio system the Tukans may be used much
like any conventional loudspeakers; i.e. with single runs of speaker cable connecting them to the
amplifier. Removing the external links on the rear of the speaker allows bi-wiring, a relatively
inexpensive method of upgrading performance. As further performance improvements are
desired a second power amplifier may be added to the system and the Tukan "passively bi-
amplified". The final step, full active bi-amplification, replaces the Tukan's internal crossover with
an external "active" electronic crossover. (For a full discussion of the benefits of bi-wired and
multi-amped operation, our Bi-Wiring & Beyond technical paper is attached.)
The small size of the Tukan also makes it ideal for use in video applications or multi-room
installations. Since the sonic characteristics of the Tukan are very similar to that of the rest of the
Linn loudspeaker range, two models, for example Tukan and Keilidh, can be comfortably
intermixed for home theatre applications in a variety of front and rear channel configurations.
Cabinet Construction
Obtaining the required high levels of performance from a speaker of this size places extreme
demands on both cabinet and drive units. As is the case with all Linn speakers, extreme care has
been taken to ensure the mechanical integrity of all components.
Ku-stone ceramic panels inside the cabinet provide additional mass and control cabinet
resonances. Unlike conventional damping materials, Ku-stone remains stable over time and is
not affected by changes in pressure or humidity.
The unusually thick front panel provides a mechanically sound mounting surface for the Linn
designed drive units. Flush mounting of the drivers and Linn's unique, vibration-free frameless
grille system ensure wide, even dispersion. Considerable attention was also applied to the design
of the Tukan's rear bass port to ensure no spurious output.
Drive Units
The ceramic tweeter was originally developed for Linn's top-of-the-range Keltik Aktiv loudspeaker
and provides smooth and detailed performance over the upper octaves.
The bass driver was designed specifically for use in the Tukan. It employs a die-cast chassis
which provides strength advantages over a typical pressed steel design. The copper voice coil is
wound on an aluminium former. This, coupled with a vented pole piece, provides high power
handling capabilities. The cone is carbon-loaded polypropylene.
The bass unit's massive magnet was limited in size only by the need for it to fit through the hole in
the front of the baffle! A second magnet mounted directly behind the primary unit focuses the
magnetic field, increasing the strength of the field around the voice coil. This not only improves
performance, it reduces extraneous magnetic emissions and allows the Tukan to be placed near
a video monitor without causing colour distortions.
Crossover
Linn-developed, state-of-the-art computer techniques have been employed in the design of the
Tukan's passive crossover network. Instead of acting as a simple high pass and low pass filter,
the internal mounted Tukan crossover actually allows for the specific electrical and mechanical
characteristics of the bass and treble units, in effect using them as part of the crossover network.
The result is an unusually accurate frequency and phase response.
The Tukan is available only through Authorised Linn Retailers all of whom have comprehensive
demonstration, installation and service capabilities.
