Performance Features
Important Information, Connector Information, 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.
•
Five Tweeter Bessel Function Array
The XLS320, XLS340, XLS360 and XCS350 utilizes five
tweeters connected 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.
•
Mirror Image Phasing High Frequency Array
The five tweeter Bessel Function Array utilizes a unique
circuit design permitting the optimization of high
frequency dispersion for Mirror Imaging. This allows for
Loudspeaker placement in a room as the Left Channel,
Center Channel or Right Channel for use in a multi-
channel system.
•
Shielded Magnetic Field
The XLS320, XLS340, XLS360 and XCS350 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 XLS320, XLS340, XLS360 and
XCS350 Loudspeaker Elements to prevent interference.
•
Special Crossover Network
The Crossover Networks used in the XLS320, XLS340,
XLS360 and XCS350 Loudspeaker Systems are designed
to ensure an even frequency response over the entire au-
dible range. The Network utilizes First, Second and Third
Order design for optimal response.
•
High Power Handling
The Loudspeaker Elements and crossover components of
the XLS320, XLS340, XLS360 and XCS350 are all chosen
for use with powerful amplifiers up to 600 watts.
•
High Efficiency
The Loudspeaker Elements used in the XLS320, XLS340,
XLS360 and XCS350 Loudspeaker Systems 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 XLS320, XLS340, XLS360 and XCS350 have built-in
Loudspeaker Element Protection in the form of automatic
resetting solid-state devices as a part of the crossover net-
work.
•
Gold Plated Input Connectors
The XLS320, XLS340, XLS360 and XCS350 input
connectors are gold plated for superior corrosion resistance
and high electrical conductivity.
•
Rigid Column Structure
The enclosures are an important part of the XLS320,
XLS340, XLS360 and XCS350 Loudspeaker Systems. The
Systems utilize a dampened rigid enclosure made from ex-
truded aluminum and houses the Loudspeaker Drivers and
Crossover. The XLS340 and XLS360 Columns, due to
their height, have additional front to back internal bracing
to form a dampened rigid Column Structure. The Column’s
small footprint allows for a variety of different placements
in a room.
