General Notes
1. It is very important that loudspeaker cables of adequate size
be used in your music system, to ensure that there will be no
power loss or heating. Cable size is specified in Gauge
numbers or AWG (American Wire Gauge). The smaller the
Gauge number, the larger the wire size:
If your loudspeaker cables are 25 feet (7.62m) or less,
use at least 18 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 16 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 14 Gauge (AWG) wire size or larger.
The Loudspeaker Connection Terminals can accept up
to 12 Gauge (AWG) wire.
2. For additional connection information, refer to the owners
manual(s) for any component(s) connected to the CS350
Loudspeaker.
3. The CS350 has built-in speaker protection in the form of three
automatic resetting solid-state devices as part of the
crossover network. One protects the tweeters, one the
midrange and the other the woofers. The characteristics of
this protection are that a certain amount of overdrive is
allowed but extended periods of overdrive will trigger
protection. If an obvious lack of high or low frequencies is
noticed, the Loudspeaker Protection Device may have
activated. Sound output from the Loudspeaker Element
affected will be reduced when the protection is triggered. The
protection devices will automatically reset when the volume
control is reduced significantly and kept low until the output
of the affected Loudspeaker Element returns to normal.

Introduction
The McIntosh CS350 Loudspeaker System is designed for
Home Theater and Music Reproduction. It is a three-way
1
system with two 6-1/2 inch LD/HP
woofers, one 4 inch
LD/HP midrange and five 1 inch dome tweeters. The
CS350 comes with a stabilizer bar that attaches to the back
of the cabinet. This bar prevents the speaker from rocking
when it is placed on its side. It is adjustable so that the
CS350 can be angled down when the speaker is placed
above the video display. The CS350 is designed to work primarily as a Center Channel Loudspeaker in a Home Theater System, but will function equally well as a Left or
Right (Main), or Surround Loudspeaker. The McIntosh logo
can clip anywhere on the grille frame. This is useful in the
event CS350s are stood on end and used as Left and Right
speakers.
The CS350 Loudspeaker performance is equivalent to
the quality of McIntoshs legendary line of Amplifiers,
Preamplifiers, Signal Processors and Signal Sources, without imparting distortion or coloration of its own. It also
complements the capabilities and the remarkably low distortion of McIntosh Power Amplifiers.
Many of todays loudspeakers are designed only for
Home Theater applications. Not so with the CS350. It is
also designed for the accurate reproduction of music. Motion picture sound effects, explosions, screams, and vehicle
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 audible
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 harmonic and
intermodulation, must be kept to a minimum. This has been
the result of the design of the new McIntosh CS350 Loudspeaker System. Each loudspeaker element and crossover
component has been carefully designed for durability, efficiency, and above all, low distortion. The McIntosh CS350
Loudspeaker System will reproduce music accurately and
function as an excellent Home Theater Loudspeaker.
Performance Features
Gold Plated Input Connectors
The CS350 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
Introduction and Performance Features
ment 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 CS350 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 CS350 Loudspeaker Elements to prevent interference.
High Power Handling
The Loudspeaker Elements and crossover components of
the CS350 are all chosen for use with powerful amplifiers
up to 350 watts.
High Efficiency
The Loudspeaker Elements used in the CS350 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 CS350 has built-in Loudspeaker Element Protection in
the form of three automatic resetting solid-state devices as
a part of the crossover network.
Adjustable Stabilizer Bar
The CS350 Loudspeaker System is equipped with an adjustable stablizer bar, attached to the back of the cabinet, to
prevent the speaker from rocking. Its adjustability allows
the CS350 to be angled down when the speaker is placed
above a video display.
Five Tweeter Bessel Function Array
The CS350 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 arrange-
