  • Page 5: Foreword

    Foreword For more than 25 years, Krell components have been the choice of discerning audiophiles all over the world. Krell customers care deeply about music, and they demand the most lifelike music reproduction possible. Krell Industries, Inc., was founded and exists to meet the expectations of those listeners.

  • Page 6: A Letter From Dan D'agostino

    Only through the design of complete systems can I insure that every component meets my standard of excellence. It is a goal of mine for Krell loudspeakers to enhance your life visually as well as sonically, and the new LAT–1000, LAT–2000, and LAT–C1000 deliver both excep- tional performance and style.
  • Page 7 With a keen understanding of this passionate drive, Krell Industries, Inc., was founded in 1980. Over the past 2-1/2 decades, Krell has earned a distinguished reputation for engi- neering innovation and product excellence. The company’s history is replete with product introductions that have deeply impacted the high-end audio industry.

Unparalleled Sonic Performance From the first Krell product —the KSA –100 —to the present, Dan D’Agostino has continually “pushed the envelope” of performance in his search for greater amplifier power, and now, loudspeaker response.

    Within the audio passband, our cabinets are sonically inert—something you cannot say about any wood or wood derivative.” Krell’s knowledge of aluminum extrusion technology has yielded an enclosure that is as purposeful as it is beautiful. Computer-optimized geometry eliminates standing wave interference.

This computer-modeled, welded aluminum case effectively iso- lates the midrange and tweeter from the main enclosure while providing an ideal operating environment for the midrange drivers.

    (38.1 cm) deep with an estimated weight of 200 lbs. (90.9 kg). Krell recommends that three to four people are needed to safely move the loud- speaker to its place in the listening area. Two people are needed to remove the shipping crate top from its base.

    Opening the LAT–2000 Shipping Box The LAT–2000. Each LAT–2000 shipping box measures 15.8 in. (40.1 cm) wide by 19.3 in. (49 cm) high by 20.3 in. (51.6 cm) deep. The combined weight of the ship- ping box and the loudspeaker is approximately 100 lbs. (45.5 kg). Each LAT–2 loudspeaker measures 10.5 in.
  • Page 15 Krell encourages you to experiment and find the loudspeaker placement that reflects your personal preference. A Lossless Acoustic Transducer (LAT) is simple to set up and use.
  • Page 16 (SECTION TWO: Unpacking and Placement continued) To Attach the Loudspeaker Grille Attach the grille to the loudspeaker before you play music. Each Lossless Acoustic Transducer (LAT) is equipped with a snap-on grille, which consists of the grille cord strung between two metal blocks. The grille is shipped in the accessory box marked “grille”.
  • Page 17 On the LAT– 2000, remove the grill block attached to the left side of the loud- speaker, by pulling it straight out. To protect the grille, Krell recommends placing it back in the grille box until you are ready to reinstall it.
  • Page 18 To Install the Spikes on the LAT–1000 Each LAT–1000 is shipped with 4 stainless steel spikes: two rear articulating spikes (with knob) and two (one long and one short) front stationary spikes (no knob). Use these spikes to stabilize and level the loudspeaker. These spikes are particularly important for sound quality if the loudspeaker will be placed on a carpeted floor.

  • Page 25 (SECTION THREE: Anatomy of a Loudspeaker continued) Cabinet Material The LAT sides are constructed of extruded 6063-T5 aluminum. The rigid, dense rear baffle made of 6061-T6 aluminum absorbs any vibration from the driver cones. Using this heavy, inert metal means minimal vibrations—no matter how much power the loudspeakers handle—and thus no loss of sound.
  • Page 26 Loudspeaker Grill Design The block and cord design of the loudspeaker grille decreases reflective surfaces and improves sound quality. The grille design also matches the ribbed configuration of the loudspeaker body, providing a sleek, unified look. Midrange/Tweeter Sub-Enclosure This feature in the LAT–1000 and the LAT– C1000 separates the midrange/tweeter and woofers into two discrete physical environments.
  • Page 27 FOUR SECTION Connecting a LAT Series Loudspeaker to Your System To connect the loudspeaker to your system: Make sure that all power sources and components are off before connecting system components. Neatly organize wiring between all system components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being intro- duced into the system.
  • Page 28 KrellHEAT: Home Theater Technology The Lossless Acoustic Transducers (LATs) are a series of loudspeakers newly designed by Krell. The LAT–C1000 and the LAT– 2000 are voiced precisely for use with the LAT–1000. Together with the Krell Master Reference Subwoofer, these components comprise a Krell High End Audio Theater (KrellHEAT) loudspeaker system.
