self resetting high current Poly-Switches to provide an
extra measure of protection.
The enclosure is an important part of the XRT1K
Loudspeaker System. The Loudspeaker System utilizes a
massive extruded alumi-
num enclosure that houses
the Loudspeaker Drivers.
Refer to figure 10. It also
has multiple front to back
internal braces to form a
dampened rigid Column
Structure. The Column’s
small footprint allows
for a variety of different
placements in a room.
Introduction and Performance Features
Performance Features
• Patented LD/HP Technology
The McIntosh Low Frequency Loudspeaker Elements
feature the patented LD/HP Magnetic Circuit Design.
This design, when compared to conventional Loudspeaker
Elements, reduces distortion significantly. It also increases
power handling and efficiency.
• Neodymium-Iron-Boron Alloy Magnets
The 44 two inch Midranges and 28 three-quarter inch
Dome Tweeters all use this Alloy. The Neodymium-Iron-
Boron Alloy has the highest flux density per unit of vol
-
ume and helps to keep the Column weight to a minimum.
• Low Harmonic and Intermodulation Distortion
The XRT1K Loudspeaker System is capable of reproduc
-
ing the full dynamic range of a symphony orchestra with
very low audible distortion of any kind.
• Large Long Low Frequency Port
The XRT1K Loudspeaker System utilizes a very large 6
inch diameter port to increase bass output, reduce distor
-
tion and improve the overall efficiency of the Loudspeaker.
• High Power Handling
The Loudspeaker Elements and Crossover Components of
the XRT1K are all chosen for use with powerful amplifiers
up to 1,200 watts.
• Superior Imaging
Locating the Tweeters between the two rows of Midranges
generates a symmetrical horizontal polar response for
superior imaging.
• Versatile Operation and Placement
In addition to the regular connections, the XRT1K Loud
-
speaker System provides separate connections for Bi-
Amplification and Tri-Amplification hookups, as well as
Bi-Wiring and Tri-Wiring.
· Extruded Column
The Column enclosure is extruded thick aluminum con
-
struction with non-parallel internal sides and is given a
High Gloss Black Piano Type Finish.
• Gold Plated Input Connectors
The XRT1K input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.
