Caution: The XLS360 Loudspeaker weight is 107 pounds (48.5kg) net. It requires two or more persons to handle safely.

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 25 feet (7.62m) or less, use at least 16 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 50 feet (15.24m) or less, use at least 14 Gauge (AWG) wire size or larger.

If the Loudspeaker Cables are 100 feet (30.48m) or less, use at least 12 Gauge (AWG) wire size or larger.

The Loudspeaker Connection Terminals can accept up to 12 Gauge (AWG) wire.

1. For additional connection information, refer to the owner's manual(s) for any component(s) connected to the XLS320, XLS340, XLS360 or XCS350 Loudspeaker.

2. The XLS and XCS Loudspeaker Systems have built-in automatic resetting solid-state devices in the crossover networks for protection. The protection allows a certain amount of overdrive, however extended periods of overdrive 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.

3. When the XLS340, XLS360 or XCS350 Loudspeaker Systems are 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/high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer.

Introduction Important Information

The McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems are designed for Home Theater and Music Reproduction. Many of today's Loudspeakers are designed only for Home Theater applications, not so with these Loudspeaker Systems. They are also designed for the accurate reproduction of music.

Motion picture sound effects, explosions, screams, and vehicle crashes require a wide dynamic range and high sound levels. These sounds are such that a speaker system having moderate distortion would reproduce them with little audible difference. This is not true with the reproduction of music. Music is by nature and definition harmonious. To reproduce it accurately, all forms of distortion, both harmonic and intermodulation, must be kept to a minimum. This has been the result of the design of the new McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems. Each loudspeaker element and crossover component has been carefully designed for low distortion, durability and efficiency. The McIntosh XLS320, XLS340, XLS360 and XCS350 Loudspeaker System will reproduce music accurately and function as an excellent Home Theater Loudspeaker.

The XLS320 is a two-way system with a 6-1/2 inch LD/HP ^1 woofer/midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XLS340 is a three-way system consisting of two 8 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XLS360 is also a three-way system with two 10 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array. The XCS350 Center Channel Loudspeaker utilizes two 8 inch LD/HP woofers, one 6-1/2 inch LD/HP midrange driver and five 1 inch dome tweeters in a Bessel Function Array.

The XLS320, XLS340, XLS360 and XCS350 Loudspeaker performance is designed to complement the capabilities of McIntosh's legendary line of Preamplifiers/Control Centers, Signal Sources Devices and Power Amplifiers, without imparting distortion or coloration.

Performance Features

• Patented LD/HP Technology

The McIntosh Low Frequency and Midrange Loudspeaker Elements feature the patented LD/HP motor structure. This design, when compared to conventional Loudspeaker Elements, reduces distortion significantly. It also increases power handling and efficiency.

- Five Tweeter Bessel Function Array

The XLS320, XLS340, XLS360 and XCS350 utilizes five tweeters connected to produce a Bessel Function Array. The individual tweeter amplitudes and phase relationships are adjusted so the array acts as a high frequency point source. One advantage of such an arrangement is a very smooth and even acoustic polar response. This allows the listener to move off axis without suffering a change in high frequency output. The use of multiple tweeters, combined with a mechanical heat sink, also provides greatly increased power handling at high frequencies.

- Mirror Image Phasing High Frequency Array

The five tweeter Bessel Function Array utilizes a unique circuit design permitting the optimization of high frequency dispersion for Mirror Imaging. This allows for Loudspeaker placement in a room as the Left Channel, Center Channel or Right Channel for use in a multi-channel system.

• Shielded Magnetic Field

The XLS320, XLS340, XLS360 and XCS350 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 XLS320, XLS340, XLS360 and XCS350 Loudspeaker Elements to prevent interference.

• Special Crossover Network

The Crossover Networks used in the XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems are designed to ensure an even frequency response over the entire audible range. The Network utilizes First, Second and Third Order design for optimal response.

• High Power Handling

The Loudspeaker Elements and crossover components of the XLS320, XLS340, XLS360 and XCS350 are all chosen for use with powerful amplifiers up to 600 watts.

• High Efficiency

The Loudspeaker Elements used in the XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems have also been designed for high efficiency. As a result any McIntosh Power Amplifier, even our smallest, will provide satisfying room filling sound.

• Automatic Overload Protection

The XLS320, XLS340, XLS360 and XCS350 have built-in Loudspeaker Element Protection in the form of automatic resetting solid-state devices as a part of the crossover network.

• Gold Plated Input Connectors

The XLS320, XLS340, XLS360 and XCS350 input connectors are gold plated for superior corrosion resistance and high electrical conductivity.

• Rigid Column Structure

The enclosures are an important part of the XLS320, XLS340, XLS360 and XCS350 Loudspeaker Systems. The Systems utilize a dampened rigid enclosure made from extruded aluminum and houses the Loudspeaker Drivers and Crossover. The XLS340 and XLS360 Columns, due to their height, have additional front to back internal bracing to form a dampened rigid Column Structure. The Column's small footprint allows for a variety of different placements in a room.

location. Also, be sure to orient the bracket as illustrated in figure 30.

1. Determine the Loudspeaker Mounting Location on the wall, making sure the Mounting Bracket will be anchored to a stud located inside the wall.

Note: Use extreme caution to avoid any existing electrical wiring, plumbing, etc., located inside the wall.

1. Refer to figures 31 thru 34 to install the appropriate Wall Bracket on the wall (orient the bracket as illustrated) using the supplied Mounting Screws. If the Flush Mount Bracket is used, attach the two cone shaped rubber

bumpers to the rear of the Loudspeaker, near the bottom.

Note: If the wall covering material and/or thickness is different from the illustration, the two supplied Mounting Screws need to be replaced with screws of the appropriate type and length.

Locating the Loudspeaker System for the XLS320

Loudspeaker placement in a room can greatly affect performance. The XLS320, XLS340, XLS360 and XCS350 are designed for use as a Left and Right Loudspeaker in a Music System, or as a Front and Surround Loudspeakers in a Home Theater System.

The optimal method for selecting speaker locations includes the use of a real time spectrum analyzer operated by the Professionals at your McIntosh Dealer. 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.

Locating Loudspeakers for use in Home Theater

In a Home Theater application, the placement of 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. Side Surround Loudspeakers work best located to either side of and above the listening position, the same distance from the monitor. Back Surround Loudspeakers work best on the back wall. Refer to figure 35.

Locating Loudspeakers for use in a Music System

When used in a Music System, the distance between the loudspeakers should not exceed the distance between the listener and either loudspeaker for the best sound imaging. Refer to figure 36. The Loudspeaker System's Tweeter Array should be inline with the listeners' ears. 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 articulate the bass notes are. Experiment with various loudspeaker positions until the locations that sound best are found.

Tweeter Array Optimization

The XLS320 Loudspeaker System incorporates a special feature in the Crossover Network for optimization of the sound coming from the five tweeter array, refer to figure 37A. The three different settings in the crossover network

have to do with the physical location of the Loudspeaker in the Home Theater and/or Music System.

Figure 37A

On the rear panel of the Loudspeaker System, there is a recessed connection plate with binding posts for connection

of hookup cables. Adjacent to the binding posts on the same recessed connection plate, are two rows of jacks with two McIntosh Jumpers already inserted, refer to figure 38A. The default position of the jumpers for the XLS320 Loudspeaker System is C, refer to figure 39A.

For the best sound performance, it is important to make sure the jumpers are set according to the Loudspeaker System loca-

Figure 38A

tion in the room. Refer to the chart below for the correct Jumper positions; if necessary, remove the two jumpers and reinsert them for the Loudspeaker location.

How to Connect the XLS320 Loudspeakers

Preparing Hookup Cables

The McIntosh Loudspeaker Systems utilize binding posts for speaker wire connections. Prepare the Loudspeaker Hookup Cables that attach to the Power Amplifier Output Terminals:

Bare wire cable ends:

Carefully remove sufficient insulation from the cable ends, refer to figures 43, 44 and 45. If the cable is

stranded, carefully twist the strands together as tightly as possible.

Note: If desired, the twisted ends can be tinned with solder to keep the strands together and/or attach a spade lug.

Spade lug or prepared wire connection:

Insert the spade lug connector or prepared section of the cable end into the terminal side access hole, and

tighten the terminal cap until the cable is firmly clamped

into the terminal so the wires cannot slip out. Refer to figures 46, 47 and 48.
