Important Information

Caution: The XRT2K when assembled weight is 452 pounds (205.0kg). It requires four or more persons to safely handle the Loudspeaker System.

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 50 feet (38.1m) or less, use at least 12 Gauge (AWG) wire size or larger. If the Loudspeaker Cables are 100 feet (76.2m) or less, use at least 10 Gauge (AWG) wire size or larger.

2. For additional connection information, refer to the owner's manual(s) for any component(s) connected to the XRT2K Loudspeaker.

3. The XRT2K's built-in speaker protection incorporates five automatic resetting solid-state devices in the crossover networks. One protects the tweeters, one for the midranges and three for the woofers. The protection allows a certain amount of overdrive but extended periods 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 XRT2K Loudspeaker System is 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 and high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer.

Introduction

For the first time, the new McIntosh XRT2K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra including pipe organ without audible distortion. McIntosh Acoustic Engineers have refined the line source Column Loudspeaker concept and the XRT2K Loudspeaker System is the 6th in a generation of that patented design ^1 . It provides superior quality midrange and high frequency sound reproduction in a full range system.

The High Frequency Section utilizes a patented Column Design ^1 with multiple two inch Midrange Inverted Titanium Dome Drivers and three-quarter inch Titanium Dome Tweeters. Refer to fig- ures 1 and 2. Since the audio power fed to a column is distributed among all the drivers, each driver does not have to work as hard, resulting in greater power handling capa- bility and a dramatic reduction in distortion. The Sound Waves from the Column produce a Cylindrical Wave Front

with a stable symmetrical horizontal sound dispersion while minimizing undesirable floor and ceiling reflections that detract from a stable sound image. Refer to figure 3. In the illustration, the Loud-

speaker on the left side

produces a Cylindrical Wave Front and the Loudspeaker on the right side produces a conventional Spherical Wave Front.

The Low Frequency Section of the System consists of six 12 inch Aluminum Cone Woofers capable of long cone excursions. The sound produced has very low levels of har-

monic distortion and a frequency response down to 16Hz.

They have a large motor assembly made with High Temperature

Black speaker cone with visible sound waves and ventilation slots (no text or symbols)

Figure 4

Neodymium magnets with inherent shielding to greatly reduce any external magnetic field. Refer to figure 4. The woofer design also utilizes an aluminum shorting ring, copper capped pole piece, three inch diameter voice coil and two cone centering devices. This results in lower distortion due to more linear magnetic flux in the voice coil gap. A good example of this low distortion is incredible smoothness and effortless clarity in the reproduction of the human voice.

The Crossover Networks used in the XRT2K Loudspeaker System are designed to ensure a smooth frequency response over the entire audible range. The Low Frequency Crossover Network is a quasi-second order design. Refer to figure 5. Along with the column arrangement, this network

Order designs keep the speakers operating within their optimum frequency range while offering the best blending of each speaker. All network inductors are air core designs; so they will not add distortion. All network capacitors are film type for extra reliability. All the Capacitors and Inductors are chosen for high current capacity. Each section of the network utilizes it own self resetting high current PTC type fuses to provide an extra measure of protection.

Performance Features

- High Temperature Neodymium-Iron-Boron Alloy Magnets

The 6 twelve inch Woofers, 64 four inch Midranges and 40 three-quarter inch Dome Tweeters all use this Alloy. The Neodymium-Iron-Boron Alloy has the highest flux density per unit of volume and helps to keep the Loudspeaker System weight to a minimum while preserving the utmost in performance.

• Shielded Magnetic Field

The XRT2K may also be used in Home Theater Installations near a television receiver or monitor without causing the television image to degrade. By design, all of the speakers' magnetic structures are inherently shielded which prevents interference.

- Low Harmonic and Intermodulation Distortion

The XRT2K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra including pipe organ without audible distortion of any kind.

• High Power Handling

The Loudspeaker Elements and Crossover Components of the XRT2K are all chosen for use with powerful amplifiers up to 2,000 watts.

- Superior Imaging

Locating the Column of Tweeters between the two Columns of Midranges generates a symmetrical horizontal polar response for superior imaging.

- Versatile Operation and Placement

In additional to the regular connections, the XRT2K Loudspeaker System provides separate connections for Bi-Amplification and Tri-Amplification hookups, as well as Bi-Wiring and Tri-Wiring.

● Extruded and Machined Side Panels and Column

The sides of the XRT2K Low Frequency enclosures and the Midrange/Tweeter Column enclosure are machined from extruded thick aluminum panels to be non-parallel and are given a High Gloss Black Piano Type Finish.

• Gold Plated Input Connectors

The XRT2K input connectors are gold plated for superior corrosion resistance and high electrical conductivity.

Room Placement

Loudspeaker placement in a room can greatly affect performance. The XRT2K Loudspeaker is designed for both Music and Home Theater Systems. The optimal method for selecting speaker locations includes the use of a real time spectrum analyzer operated by an experienced system installer. An uncompromising installation would take into consideration the floor, wall and ceiling coverings, the type and placement of furniture and can even include the architectural design of the room and its construction materials. In those instances where placement in the room is fixed an environmental equalizer may be needed to restore proper musical balance.

Placement near a wall, corner, floor, ceiling or any intersecting surfaces will reinforce some bass frequencies. Which bass frequencies are boosted by placement in a particular location is dependent on the dimensions of the room. Test the various Loudspeaker locations by playing music with continuous bass, setting up the speakers and listening to them from the main listening spot. Move the Loudspeakers to an alternate location and repeat the listening, paying attention to how the bass qualities and response levels change. Do not assume the loudest bass is best; rather listen for booming (a lack of articulation), as well as a balance over the whole spectrum, to assure the bass will not drown out the other parts of the music. Experiment with various Loudspeaker positions until the locations that sound best are found.

The XRT2K Midrange/High Frequency Column's Smooth Frequency Response may be altered by large object(s) located in the sound waves path or by locating the column too close to a side wall. There should be an unobstructed area in front of the column of at least 60 degrees either side from the center axis for the best performance. Refer to figure 9.

Locating Loudspeakers for use in Home Theater

In a Home Theater application, the placement of Left and Right Front Loudspeakers can be limited by such considerations as the size and location of the video monitor. The locating suggestions in the “for use in a Music System” section below can still be helpful as a starting place. Refer to figure 10.

Locating Loudspeakers for use in a Music System

When used in a Music System the distance between the Loudspeakers and the listener to the Loudspeakers should form a equilateral to an acute isosceles triangle. If the speakers are too far apart relative to the listener, some imaging can be lost. Refer to figure 11.
