that is immune to vibration. Articulating spikes allow the LAT–1 to be precisely leveled
for the most accurate imaging and reduced vibration. A special sub-enclosure in
the LAT–1 and LAT–C houses the drivers for the midrange and the tweeter. This
computer-modeled, welded aluminum case effectively isolates the midrange and
tweeter from the main enclosure while providing an ideal operating environment for
the midrange drivers.
The LAT–C enclosure is fashioned out of solid aluminum billet and extrusion,
creating an operating environment for the drivers that is free of induced vibrations.
The loudspeaker has a special advantage in the crucial midrange frequencies: it
is optimized for center channel data reproduction, or dialogue, the single most
important job of a center channel speaker. The LAT–C maintains the voice match-
ing necessary to recreate seamless multi-channel front staging. Heard through the
LAT–C, dialogue is natural sounding and clearly distinguishable from the rest of the
audio program.
The LAT– 2 construction is based on the same engineering principles that distinguish
the LAT–1. The all-aluminum enclosure features wall thickness ranging from 0.75 to
1.0 inch. The curvature of the cabinets is designed to absolutely minimize the effects
of internal standing waves and external high-frequency diffraction. The vented cabinet
of the LAT– 2 features two rear bass ports. Resembling the LAT–1 ports in design, the
LAT– 2 ports are precisely dimensioned, flared, and positioned with respect to the
woofer to eliminate turbulence while providing the correct acoustical loading.
Drivers
The LAT–1 and the LAT–C tweeters have a dual concentric design, with very low
ultrasonic resonance and a response beyond 50 kHz. The segmented cones of the
midrange driver reduce self-induced resonance. This midrange driver also features
a cast magnesium frame with low profile spars in a radial design that reduces
reflections. An asymmetrical spider lowers distortion. The woofers, custom made
for Krell and matched specifically to the enclosure, are operated without attenuation
for maximum system efficiency and power transmission.
The LAT– 2 tweeter is identical to the LAT–1 tweeter, and the 7-inch (18 cm) mid-bass
driver features the same multifaceted cone construction and proprietary suspension
design as the midrange drivers in the LAT–1. This advanced driver design simultane-
ously ensures extraordinary bass reproduction and outstanding midrange accuracy.
