IntroductionImportant Information

1LD/HP Pat. No. 5,151,943

The McIntosh XLS320, XLS340, XLS360 and XCS350Loudspeaker Systems are designed for Home Theater andMusic Reproduction. Many of today’s Loudspeakers aredesigned only for Home Theater applications, not so withthese Loudspeaker Systems. They are also designed for theaccurate reproduction of music.

Motion picture sound effects, explosions, screams, andvehicle crashes require a wide dynamic range and highsound levels. These sounds are such that a speaker systemhaving moderate distortion would reproduce them withlittle audible difference. This is not true with the reproduc-tion of music. Music is by nature and definition harmoni-ous. To reproduce it accurately, all forms of distortion, bothharmonic and intermodulation, must be kept to a minimum.This has been the result of the design of the new McIntoshXLS320, XLS340, XLS360 and XCS350 LoudspeakerSystems. Each loudspeaker element and crossover compo-nent has been carefully designed for low distortion, dura-bility and efficiency. The McIntosh XLS320, XLS340,XLS360 and XCS350 Loudspeaker System will reproducemusic accurately and function as an excellent Home The-ater Loudspeaker.

The XLS320 is a two-way system with a 6-1/2 inch LD/HP1 woofer/midrange driver and five 1 inch dome tweetersin a Bessel Function Array. The XLS340 is a three-waysystem consisting of two 8 inch LD/HP woofers, one 6-1/2inch LD/HP midrange driver and five 1 inch dome tweetersin a Bessel Function Array. The XLS360 is also a three-way system with two 10 inch LD/HP woofers, one 6-1/2inch LD/HP midrange driver and five 1 inch dome tweetersin a Bessel Function Array. The XCS350 Center ChannelLoudspeaker utilizes two 8 inch LD/HP woofers, one 6-1/2inch LD/HP midrange driver and five 1 inch dome tweetersin a Bessel Function Array.

The XLS320, XLS340, XLS360 and XCS350 Loud-speaker performance is designed to complement the capa-bilities of McIntosh’s legendary line of Preamplifiers/Con-trol Centers, Signal Sources Devices and Power Amplifi-ers, without imparting distortion or coloration.

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

1. Loudspeaker Cables of adequate size are important to ensurethat there will be no significant power loss or heating. Cablesize is specified in Gauge numbers or AWG (American WireGauge). The smaller the Gauge number, the larger the wiresize:

If the Loudspeaker Cables are 25 feet (7.62m) or less, use atleast 16 Gauge (AWG) wire size or larger.If the Loudspeaker Cables are 50 feet (15.24m) or less, use atleast 14 Gauge (AWG) wire size or larger.If the Loudspeaker Cables are 100 feet (30.48m) or less, useat least 12 Gauge (AWG) wire size or larger.The Loudspeaker Connection Terminals can accept up to 12Gauge (AWG) wire.

2. For additional connection information, refer to the owner’smanual(s) for any component(s) connected to the XLS320,XLS340, XLS360 or XCS350 Loudspeaker.

3. The XLS and XCS Loudspeaker Systems have built-inautomatic resetting solid-state devices in the crossovernetworks for protection. The protection allows a certainamount of overdrive, however extended periods of overdrivewill trigger protection. If an obvious lack of high, mid or lowfrequencies is noticed, the Protection Device may haveactivated. These devices will automatically reset when thevolume level is reduced significantly and kept low until theoutput of the affected Loudspeaker Element returns to normal.

4. When the XLS340, XLS360 or XCS350 Loudspeaker Systemsare driven by more than one amplifier, the output levels of thedifferent amplifiers connected to the Loudspeaker Systemmust be adjusted to achieve a proper balance between thelow, midrange/high frequencies reproduced. This adjustmentis best achieved through the use of audio test equipmentoperated by a qualified installer.

Performance Features

Important Information, Connector Information, Introduction and Performance Features

• Patented LD/HP TechnologyThe McIntosh Low Frequency and Midrange LoudspeakerElements feature the patented LD/HP motor structure. Thisdesign, when compared to conventional LoudspeakerElements, reduces distortion significantly. It also increasespower handling and efficiency.

• Five Tweeter Bessel Function ArrayThe XLS320, XLS340, XLS360 and XCS350 utilizes fivetweeters connected to produce a Bessel Function Array.The individual tweeter amplitudes and phase relationshipsare adjusted so the array acts as a high frequency pointsource. One advantage of such an arrangement is a verysmooth and even acoustic polar response. This allows thelistener to move off axis without suffering a change in highfrequency output. The use of multiple tweeters, combinedwith a mechanical heat sink, also provides greatlyincreased power handling at high frequencies.

• Mirror Image Phasing High Frequency ArrayThe five tweeter Bessel Function Array utilizes a uniquecircuit design permitting the optimization of highfrequency dispersion for Mirror Imaging. This allows forLoudspeaker placement in a room as the Left Channel,Center Channel or Right Channel for use in a multi-channel system.

• Shielded Magnetic FieldThe XLS320, XLS340, XLS360 and XCS350 may be usedin Home Theater Installations near a television receiver ormonitor without causing the television image to degrade.McIntosh has designed special shielding around themagnetic structure of the XLS320, XLS340, XLS360 andXCS350 Loudspeaker Elements to prevent interference.

• Special Crossover NetworkThe Crossover Networks used in the XLS320, XLS340,XLS360 and XCS350 Loudspeaker Systems are designedto ensure an even frequency response over the entire au-dible range. The Network utilizes First, Second and ThirdOrder design for optimal response.

• High Power HandlingThe Loudspeaker Elements and crossover components ofthe XLS320, XLS340, XLS360 and XCS350 are all chosenfor use with powerful amplifiers up to 600 watts.

• High EfficiencyThe Loudspeaker Elements used in the XLS320, XLS340,XLS360 and XCS350 Loudspeaker Systems have alsobeen designed for high efficiency. As a result any McIntoshPower Amplifier, even our smallest, will provide satisfyingroom filling sound.

• Automatic Overload ProtectionThe XLS320, XLS340, XLS360 and XCS350 have built-inLoudspeaker Element Protection in the form of automaticresetting solid-state devices as a part of the crossover net-work.

• Gold Plated Input ConnectorsThe XLS320, XLS340, XLS360 and XCS350 inputconnectors are gold plated for superior corrosion resistanceand high electrical conductivity.

• Rigid Column StructureThe enclosures are an important part of the XLS320,XLS340, XLS360 and XCS350 Loudspeaker Systems. TheSystems utilize a dampened rigid enclosure made from ex-truded aluminum and houses the Loudspeaker Drivers andCrossover. The XLS340 and XLS360 Columns, due totheir height, have additional front to back internal bracingto form a dampened rigid Column Structure. The Column’ssmall footprint allows for a variety of different placementsin a room.

1. Using the supplied Allen Wrench, remove the threescrews securing the Stabilizer Bar to the back of theXCS350. Refer to figure 26. Replace the just removedcenter screw with a supplied one of the same type, butshorter length. Refer to figure 28.

Note: Retain the three removed screws and Stabilizer Barfor possible future use.

2. Attach either the flush mount or angle mount bracketsto the rear of the Loudspeaker using the suppliedscrews. Refer to figures 27, 28 and 29 for the screwlocation. Also, be sure to orient the bracket as illus-trated in figure 30.

3. Determine the LoudspeakerMounting Location on the wall,making sure the Mounting Bracketwill be anchored to a stud locatedinside the wall.

Note: Use extreme caution to avoidany existing electricalwiring, plumbing, etc.,located inside the wall.

4. Refer to figures 31 thru 34 to in-stall the appropriate Wall Bracketon the wall (orient the bracket asillustrated) using the suppliedMounting Screws. If the FlushMount Bracket is used, attach thetwo cone shaped rubber

bumpers to the rear of the Loudspeaker, near the bot-tom.

Note: If the wall covering material and/or thickness isdifferent from the illustration, the two suppliedMounting Screws need to be replaced with screwsof the appropriate type and length.

5. Orient the Loudspeaker to line up with the Wall Brack-ets and attach them together. If the angle mount isused, install the Lock-ing Screw to securethe Loudspeaker atthe desired angle.

Installation, con’tLocating the Loudspeaker SystemLoudspeaker placement in a room can greatly affectperformance. The XLS320, XLS340, XLS360 and XCS350are designed for use as a Left and Right Loudspeaker in aMusic System, or as a Front and Surround Loudspeakers ina Home Theater System.

The optimal method for selecting speaker locations in-cludes the use of a real time spectrum analyzer operated bythe Professionals at your McIntosh Dealer. An uncompro-mising installation would take into consideration the floor,wall and ceiling coverings, the type and placement of furni-ture and can even include the architectural design of theroom and its construction materials.

Locating Loudspeakers for use in Home TheaterIn a Home Theater application, the placement of FrontLoudspeakers can be limited by such considerations as thesize and location of the video monitor. The locatingsuggestions in the “for use in a Music System” sectionbelow can still be helpful. Side Surround Loudspeakerswork best located to either side of and above the listeningposition, the same distance from the monitor. BackSurround Loudspeakers work best on the back wall. Referto figure 35.

Locating Loudspeakers for use in a Music SystemWhen used in a Music System, the distance between theloudspeakers should not exceed the distance between thelistener and either loudspeaker for the best sound imaging.Refer to figure 36. The Loudspeaker System’s TweeterArray should be inline with the listeners’ ears. Placementnear a wall, corner, floor, ceiling or any intersectingsurfaces will reinforce some bass frequencies. Which bassfrequencies are boosted by placement in a particularlocation is dependent on the dimensions of the room. Testthe various loudspeaker locations by playing music withcontinuous bass, setting up the speakers and listening tothem from the main listening spot. Move the loudspeakersto an alternate location and repeat the listening, payingattention to how articulate the bass notes are. Experimentwith various loudspeaker positions until the locations thatsound best are found.

Tweeter Array OptimizationThe XLS320, XLS340, XLS360 and XCS350 LoudspeakerSystems incorporate a special feature in the CrossoverNetwork for optimization of the sound coming from thefive tweeter array, refer to figure 37. The three differentsettings in thecrossover networkhave to do with thephysical location ofthe Loudspeaker inthe Home Theaterand/or Music System.

On the rear panel of the Loudspeaker System there is arecessed connectionplate with bindingposts for connection ofhookup cables. Adja-cent to the bindingposts on the same re-cessed connectionplate, are two rows ofjacks with two McIn-tosh Jumpers alreadyinserted, refer to figure38. The default postionof the jumpers for theXLS320, XLS340, andXLS360 LoudspeakerSystems, is RIGHT,refer to figure 39. TheXCS350’s defaultpostion of the jumpersis CENTER, refer to figure 40.

For the best sound performance, it is important to makesure the jumpers are set according to the Loudspeaker Sys-tem location in the room. Refer to the chart below for thecorrect Jumper positions; if necessary, remove the twojumpers and reinsert them for the Loudspeaker location.

Preparing Hookup CablesThe McIntosh Loudspeaker Systems utilize binding postsfor speaker wire connections. Prepare the LoudspeakerHookup Cables that attach to the Power Amplifier OutputTerminals:

Bare wire cable ends:Carefully remove sufficient insulation from the cableends, refer to figures 43, 44 and 45. If the cable isstranded, care-fully twist thestrands to-gether astightly as pos-sible.

Note: If desired, the twisted ends can be tinned withsolder to keep the strands together and/or attach aspade lug.

Spade lug or prepared wire connection:Insert the spade lug connector or prepared section ofthe cable end into the terminal side access hole, andtighten theterminalcap untilthe cableis firmlyclampedinto the terminal so the wires cannot slip out. Refer tofigures 46, 47 and 48.
