Introduction and Performance Features
response over the entire audible range. The Network uti- lizes both Second and Third Order design utilizing Capaci- tors and Inductors with high current capacity. Refer to fig- ure 6. There are two different types of low loss (DCR) In- ductors in the network, each one chosen not to exhibit any core saturation even at high power levels. This prevents the addition of distortion to the music at any frequency. The Capacitors used include low loss (ESR) Polypropy- lene and Mylar types. The Network also utilize self reset- ting high current
The enclo- sures are an im- portant part of the XRT28 Loud- speaker System. The Loudspeaker System utilizes a massive extruded
aluminum enclosure that houses the 20 four inch Midrange and 16 one inch Tweeter Drivers. Refer to figure 7. It also has multiple front to back internal braces to form a damp- ened rigid Column Structure. The Column’s small foot- print allows for a variety of different placements in a room.
Performance Features
•Patented LD/HP Technology
The McIntosh Low Frequency and Midrange 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 20 four inch Midranges and 16 one inch Dome Tweet- ers all use this Alloy. The
•Shielded Magnetic Field
The XRT28 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 XRT28 Loudspeaker Elements to prevent interference.
•High Power Handling
The Loudspeaker Elements and Crossover Components of the XRT28 are all chosen for use with powerful amplifiers up to 1,200 watts.
•Superior Imaging
Locating the Column of Tweeters between the two Columns of Midranges helps to generate a symmetrical horizontal polar response for superior imaging.
•Versatile Operation and Placement
In additional to the regular connections, the XRT28 Loud- speaker System provides separate connections for
•Gold Plated Input Connectors
The XRT28 input connectors are gold plated for superior corrosion resistance and high electrical conductivity.
