The McIntosh XLS320, XLS340, XLS360 and XCS350
Loudspeaker Systems are designed for Home Theater and
Music Reproduction. Many of today’s Loudspeakers are
designed only for Home Theater applications, not so with
these Loudspeaker Systems. They are 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 reproduc-
tion of music. Music is by nature and definition harmoni-
ous. 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
XLS320, XLS340, XLS360 and XCS350 Loudspeaker
Systems. Each loudspeaker element and crossover compo-
nent has been carefully designed for low distortion, dura-
bility and efficiency. The McIntosh XLS320, XLS340,
XLS360 and XCS350 Loudspeaker System will reproduce
music accurately and function as an excellent Home The-
ater Loudspeaker.
The XLS320 is a two-way system with a 6-1/2 inch LD/
HP 1 woofer/midrange driver and five 1 inch dome tweeters
in a Bessel Function Array. The XLS340 is a three-way
system consisting of two 8 inch LD/HP woofers, one 6-1/2
inch LD/HP midrange driver and five 1 inch dome tweeters
in a Bessel Function Array. The XLS360 is also a three-
way system with two 10 inch LD/HP woofers, one 6-1/2
inch LD/HP midrange driver and five 1 inch dome tweeters
in a Bessel Function Array. The XCS350 Center Channel
Loudspeaker utilizes two 8 inch LD/HP woofers, one 6-1/2
inch LD/HP midrange driver and five 1 inch dome tweeters
in a Bessel Function Array.
The XLS320, XLS340, XLS360 and XCS350 Loud-
speaker performance is designed to complement the capa-
bilities of McIntosh’s legendary line of Preamplifiers/Con-
trol Centers, Signal Sources Devices and Power Amplifi-
ers, without imparting distortion or coloration.
Caution: The XLS360 Loudspeaker weight is 107 pounds
(48.5kg) net. It requires two or more persons to handle
safely.
1. Loudspeaker Cables of adequate size are important to ensure
that there will be no significant 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 the Loudspeaker Cables are 25 feet (7.62m) or less, use at
least 16 Gauge (AWG) wire size or larger.
If the Loudspeaker Cables are 50 feet (15.24m) or less, use at
least 14 Gauge (AWG) wire size or larger.
If the Loudspeaker Cables are 100 feet (30.48m) or less, use
at least 12 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 owner’s
manual(s) for any component(s) connected to the XLS320,
XLS340, XLS360 or XCS350 Loudspeaker.
3. The XLS and XCS Loudspeaker Systems have built-in
automatic resetting solid-state devices in the crossover
networks for protection. The protection allows a certain
amount of overdrive, however extended periods of overdrive
will trigger protection. If an obvious lack of high, mid or low
frequencies is noticed, the Protection Device may have
activated. These devices will automatically reset when the
volume level is reduced significantly and kept low until the
output of the affected Loudspeaker Element returns to normal.
4. When the XLS340, XLS360 or XCS350 Loudspeaker Systems
are driven by more than one amplifier, the output levels of the
different amplifiers connected to the Loudspeaker System
must be adjusted to achieve a proper balance between the
low, midrange/high frequencies reproduced. This adjustment
is best achieved through the use of audio test equipment
operated by a qualified installer.
