Introduction and Performance Features

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

1

 woofers, one 8 inch LD/

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

LD/HP Pat. No. 5,151,943

• 

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.

• 

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.
