LS360 Owner's Manual

Introduction

The McIntosh LS360 Loudspeaker System is designed for
Home Theater and Music Reproduction. It is a three-way
system with two 10 inch LD/HP
HP midrange and five 1 inch dome tweeters. The LS360 is
designed to work as a Left or Right (Main) Loudspeaker in
a Music System, or as a Main or Surround Loudspeaker in
a Home Theater System.
The LS360 Loudspeaker performance is equivalent to
the quality of McIntosh’s legendary line of Amplifiers,
Preamplifiers, Signal Processors and Signal Sources, with-
out imparting distortion or coloration of its own. It also
complements the capabilities and the remarkably low dis-
tortion of McIntosh Power Amplifiers.
Many of today’s loudspeakers are designed only for
Home Theater applications. Not so with the LS360. It is
also designed for the accurate reproduction of music. Mo-
tion picture sound effects, explosions, screams, and ve-
hicle crashes require a wide dynamic range and high sound
levels. These sounds are such that a speaker system having
moderate distortion would reproduce them with little au-
dible difference. This is not true with the reproduction of
music. Music is by nature and definition harmonious. To
reproduce it accurately, all forms of distortion, both har-
monic and intermodulation, must be kept to a minimum.
This has been the result of the design of the new McIntosh
LS360 Loudspeaker System. Each loudspeaker element
and crossover component has been carefully designed for
durability, efficiency, and above all, low distortion. The
McIntosh LS360 Loudspeaker System will reproduce mu-
sic accurately and function as an excellent Home Theater
Loudspeaker.

Performance Features

•
Gold Plated Input Connectors
The LS360 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
•
Five Tweeter Bessel Function Array
The LS360 utilizes five tweeters wired to produce a Bessel
Function Array. The individual tweeter amplitudes and
phase relationships are adjusted so the array acts as a high
frequency point source. One advantage of such an
arrangement is a very smooth and even acoustic polar
response. This allows the listener to move off axis without
suffering a change in high frequency output. The use of
multiple tweeters, combined with a mechanical heat sink,
also provides greatly increased power handling at high
frequencies.

Introduction and Performance Features
•
Patented LD/HP Technology
The McIntosh Low Frequency and Midrange Loudspeaker
Elements feature the patented LD/HP motor structure. This
design, when compared to conventional Loudspeaker
Elements, reduces distortion significantly. It also increases
power handling and efficiency.
•
Shielded Magnetic Field
The LS360 may be used in Home Theater Installations
near a television receiver or monitor without causing the
television image to degrade. McIntosh has designed
special shielding around the magnetic structure of the
LS360 Loudspeaker Elements to prevent interference.
•
High Power Handling
The Loudspeaker Elements and crossover components of
the LS360 are all chosen for use with powerful amplifiers
up to 600 watts.
•
High Efficiency
The Loudspeaker Elements used in the LS360
Loudspeaker System have also been designed for high
efficiency. As a result any McIntosh Power Amplifier, even
our smallest, will provide satisfying room filling sound.
•
Automatic Overload Protection
The LS360 has built-in Loudspeaker Element Protection in
the form of three automatic resetting solid-state devices as
a part of the crossover network.
•
Flared Acoustic Bass Ports
The Acoustic Bass Ports in the LS360 have flared front
and rear openings to eliminate air movement noise.
