Page 6: Introduction And Safety Information
MODEL NUMBER USAGE IN THIS MANUAL Within this manual XLT and XLTE models are generally referred to only by their numerical suffixes. For example, model ‘43’ refers to both the XLT43 and XLT43E. Where information applies only to a specific model, such as only to the XLT46 but not the XLT46E, the complete model number is used. -
Page 7: Unpacking And Inspection
UNPACKING AND INSPECTION The Community XLT and XLTE loudspeakers are inherently rugged and are carefully packed in well-designed cartons. It is a good idea to inspect the unit carefully after it has been removed from the packaging, as sometimes there is hidden damage due to some unfortunate incident in shipment. -

Page 13: Community Xlt And Xlte Series General Description
COMMUNITY XLT™ AND XLTE™ SERIES GENERAL DESCRIPTION The XLT loudspeaker systems have features and functions designed primarily for portable applications. The XLTE systems are suitable for both heavier-duty portable use and for permanent installation. From the smallest to the largest model, these loudspeakers represent Community’s commitment to meeting the audio requirements for sound reinforcement with performance, quality, and reliability at affordable prices. - Page 14 Ferrofluid Cooling All XLT and XLTE low frequency drivers and the 46 mid frequency driver are specifically designed to be Ferrofluid- cooled. Ferrofluid is a viscous liquid that is attracted by magnetic fields. The liquid is injected into the voice coil gap during manufacturing and is permanently retained by the magnetism in the gap.

ENCLOSURES XLT: These enclosures are constructed of OSB (Oriented Strand Board). This wood is a type of composite board specially constructed with the wood grains oriented in one direction. This results in a much stronger material for a given weight than other types of composite wood materials. - Page 16 Each enclosure has provisions for permanently installing it. XLT: These models have four 5/16-18 threaded T-nuts - one each in the top, sides, and bottom. The XLT48 has two mounting points - one on each of the two sides. These points are designed to be used with Community’s optional CSSUPKIT or WB1 mounting kits for permanent installations.
- Page 17 The straps have a series of 3/8 in. / 9.5 mm diameter holes for attachment to rigging. WB1 – Two steel brackets that can be attached to the T-nuts on XLT and XLT48E models. Used for mounting to walls or ceilings.

Recommended Amplifier Power for Specific Models TABLES 3, 4, and 5 list the recommended amplifier power for all of the XLT and XLTE models. The power figures listed indicate amplifier RMS ratings and assume this a 20 Hz – 20 kHz power rating per amplifier channel. -

Table 5: Recommended Amplifier Power for Subwoofer SYSTEM CONFIGURATIONS FIGURE 2 and FIGURE 3 show the possible configurations for the XLT and XLTE loudspeakers and subwoofers. FIGURE 2 shows the possible configurations when your full-range system is operated in PASSIVE mode both with and without an XLT or XLTE subwoofer. -

If you have a choice of filter types, the Butterworth type should work well. Adjust the acoustical balance between the full-range loudspeaker and the subwoofer by using the amplifier input level controls or the crossover output level controls.

The grille is purposely tight fitting to prevent the metal from resonating so it may require some force to pull it away. Be careful not to catch the carpet pile with the edges on the XLT models. Do not loose any of the grille standsoffs To reinstall the grille, make sure that the grille is correctly oriented so that holes in the grille line up with all of the standoffs that should be positioned in their recesses. -
Page 27: Mounting And Rigging
IMPORTANT NOTE: Mounting/Rigging Point Holes All mounting/rigging points, T-nut mounting points, and stand adapter points for all XLT and XLTE loudspeakers must either be used for mounting hardware or remain plugged with the supplied screws. If they are not plugged up, these points can create air leaks in the enclosure that will compromise the LF performance with reduced output and/or distortion. -

Stand Bracket Inserts (46 and 48 only) For pole or stand mounting, XLT and XLTE models 46 and 48 have two 5/16-18 threaded inserts (T-nuts) on the bottom of the 46 and top of the 48. They are spaced 5.5 in. / 140 mm apart to mate with an Ultimate Support BMB- 200K stand bracket or similar hardware. -

This can put the full-range loudspeaker at or above the audience’s ear level to provide greater projection of sound to the rear of the audience. Both the XLT and XLTE enclosures have provisions to help prevent the top enclosure from moving around due to sound vibrations or from sliding off if accidentally bumped. -

Ohms or higher) or a piezo-electric tweeter and listen for noticeable distortion at the output of each piece of equipment. This point will be just above the maximum output. Without some method of determining the maximum output on each piece of equipment, you cannot expect to optimize the gain structure. PAGE Community XLT / XLTE Series Owner’s Manual... - Page 32 8.2.2 Residual Noise XLT and XLTE loudspeakers have high sensitivities. This means that they produce a relatively high volume of sound for a given electrical input. This also includes the residual electronic noise of an audio system. By setting gain structure properly and using high quality, professional electronics with balanced connections, this noise should be at or near inaudibility.

RMS rating and do not test at this 25% level for more than a few moments. If test signals must be used for extended periods of time, the power input to the loudspeaker should be kept below 10% of the loudspeaker’s RMS rating to ensure the loudspeaker will not be damaged.
