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 pat- ented design1. It provides

superior quality midrange and high frequency sound reproduction in a full range system.

The High Frequency Section utilizes a patented Column Design1 with mul- tiple 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 de- tract from a

stable sound im- age. Refer to figure 3. In the illus- tration, 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 dis-

tortion and

afre- quency re- sponse down to 16Hz. They have a large mo- tor assem- bly made with High Tempera-

ture

Neodymium magnets with inherent shielding to greatly re- duce any external magnetic field. Refer to figure 4. The woofer design also utilizes an aluminum shorting ring, cop- per 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 Loud-

speaker 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

XRT2K specifications

The McIntosh XRT2K stands as a monumental achievement in the world of high-fidelity loudspeakers, reflecting the brand's commitment to superior sound engineering and aesthetic design. Known for its distinctive look and powerful performance, this model blends cutting-edge technology with timeless craftsmanship, appealing to audio enthusiasts and professionals alike.

One of the most significant features of the XRT2K is its innovative speaker configuration. The design incorporates an array of drivers, including a high-frequency section with multiple tweeters that ensure detailed, clear highs. This is complemented by mid-range drivers that provide a full-bodied representation of vocals and instruments. The lower section features powerful woofers designed to deliver deep, controlled bass, creating a three-dimensional soundstage that envelops listeners.

The XRT2K utilizes McIntosh's proprietary techniques, such as its advanced driver alignment, which ensures precise timing and phase coherence across the audio spectrum. This results in an immersive listening experience where every note is accurately reproduced, maintaining the integrity of the original recording. The speaker’s unique design also minimizes unwanted resonances and distortions, allowing for a cleaner and more accurate sound.

Another standout characteristic of the XRT2K is its broad frequency response, which enables it to reproduce a wide range of musical genres effortlessly. Whether one is enjoying classical music with its intricate detail or high-energy rock tracks with throbbing bass, the XRT2K can handle it all without compromise. The depth of the soundstage is further enhanced by the speaker's ability to convey spatial information, allowing listeners to feel as though they are in the same room as the performers.

In terms of aesthetics, the XRT2K epitomizes luxury. Its sleek, modern design is complemented by iconic McIntosh styling, featuring glass panels, polished aluminum, and the signature blue VU meters. This not only makes it a visually striking addition to any audio setup but also matches well with high-end AV systems and home theaters.

Overall, the McIntosh XRT2K is a remarkable fusion of technology, craftsmanship, and design. With its advanced driver technology, meticulous engineering, and striking aesthetics, it stands out in the luxury audio market, promising an unparalleled listening experience that can satisfy the most discerning audiophiles.
