Introduction

The new McIntosh XCS2K Loudspeaker System is a Center Channel Loudspeaker capable of reproducing the full dynamic range of a symphony orchestra with very low audible distortion. It is the perfect match to the famous XRT2K Column Loudspeakers, when used in a Home Theater / Music System. It uses the same acoustic technol- ogy found in the XRT2K Column Loudspeakers developed by the McIntosh Acoustic Engineers. The technology has been refined over the years and is now the 6th generation of the design and provides superior quality sound repro- duction in a full range system.

The XCS2K Loudspeaker utilizes a Horizontal Arc Array Design with three-quarter inch Titanium Dome Tweeters and multiple rows of two inch Mid- range Inverted Titanium Dome Drivers. Refer to figures 1, 2A and 2B. The Sound Waves from this Horizontal Arc Array pro- duce a stable and focused symmetrical horizontal sound image. Since the

audio power fed to each row is distributed among all the drivers, each driver does not have to work as hard, resulting in greater power han- dling capability, greatly reduced power com- pression and a dramatic reduction in distortion.

The Low Frequency Section of the System consists of three 12 inch Aluminum Cone Woofers capable of long cone excursions. Refer to figure 3. The sound produced has very low levels of harmonic distortion and a frequency re- sponse down

to 16Hz. They have a large motor as- sembly made with High Temperature Neodymium magnets with inherent shielding to greatly reduce any external

magnetic field. The woofer design also utilizes an alu- minum shorting ring and copper capped pole piece. This results in lower distortion due to more linear magnetic flux in the voice coil gap. A good example of this low distor- tion is incredible smoothness and effortless clarity in the reproduction of the human voice.

The Crossover Networks used in the XCS2K Loud- speaker System are phase matched between the Low Frequency, Midrange and High Frequency Sections to ensure a smooth frequency response over the entire audible range. Refer to figures 4, 5 and 6. The crossover inductors are selected so they will not add audible distortion. The 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 PPTC type fuses to provide an extra measure of protection.
