The LAT-2 brings the extraordinary
power and clarity of the LAT-1 to a
2-way, bookshelf design. Use the
LAT-2 wherever space is at
premium, but the utmost in sonic
purity is demanded. The LAT-2 is
based on the same design
principles that distinguish the Krell
Lossless Acoustic Transducer
concept. Sophisticated engineering
and uncompromised construction
result in dynamic, transparent,
uncannily accurate sound
reproduction rarely achieved in any
speaker, regardless of size or the
number of drivers.
FEATURES
All Krell LAT loudspeakers feature massive aluminum
construction. The enclosures range from 0.75 to 1.5 inches in
wall thickness. 3-way designs feature an internal
midrange/tweeter sub-enclosure that is constructed of heavy
aluminum plate. The shape of the enclosures is determined by
custom aluminum extrusions, the curvatures of which are
designed to absolutely minimize the effects of internal standing
waves and external high-frequency diffraction. Such extensive
use of aluminum may seem extravagant, but the sonic benefits
are undeniable. Other than concrete and lead, which are not
practical choices, aluminum possesses the ideal combination of
structural rigidity and resonance damping characteristics. Within
the audio passband, Krell LAT loudspeaker enclosures are
sonically inert--something that cannot be said about any wood
or wood derivative.
The LAT-2 vented cabinet features two rear bass ports precisely
dimensioned and positioned with respect to the woofer to
eliminate turbulence while providing the correct acoustic loading.
A 2nd-order Bessel crossover preserves phase coherence and
optimizes power response. All crossover circuitry utilizes 1/8-inch
thick glass epoxy circuit boards with 4 oz. copper traces,
ensuring low microphonics, low resistance, low inductance, and
high current handling. Network inductors are all air-core pure
copper designs. Individually potted polypropylene WIMA
capacitors are used in parallel to minimize inductance and
resistance, and improve current handling.
The 7-inch (18 cm) midbass drive unit used in the LAT-2
features the same multifaceted cone construction and proprietary
