4 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.

4.1ABBREVIATED OPERATING INSTRUCTIONS

This General Description Chapter about the features and functions can serve as abbreviated operating instructions on how to use your new product. More detailed information can be found in the chapters that follow.

4.2MODELS (See Appendix for details about XLT41E and XLT48E model variations)

The full-range loudspeakers reproduce all but the very deepest bass frequencies. The HF drivers (and MF driver in the 46) are horn-loaded for maximum efficiency and for directional control of the sound. For additional bass output at the extreme low end of the audio frequency range, model 51 or 55 subwoofers can be used with the full-range loudspeakers to produce added depth and impact. The 51 and 55 subwoofers are ported (bass reflex) designs, engineered to match the enclosure sizes and acoustic performance of the full-range loudspeakers.

4.3DRIVERS

All systems use proprietary drivers built to precise Community designs and specifications using the latest in materials technology and design philosophy.

4.3.1High Frequency Driver

The high frequency driver for all full-range systems is a 1 in. / 25 mm exit compression driver with a 2 in. / 51 mm diameter titanium diaphragm. It provides high power handling capabilities while retaining the small diaphragm area necessary to reproduce the small wavelengths of the highest audible frequencies.

4.3.2Mid Frequency Driver (46 models only)

The midrange driver in the 46 models is a Ferrofluid cooled 6.5 in. / 165 mm horn loaded cone driver. Its long excursion, low compression ratio design results in exceptionally low distortion. The large magnetic structure provides high sensitivity along with high power handling that extends well below its 500 Hz crossover point.

4.3.3Low Frequency Drivers

The low frequency drivers in all models are high sensitivity cone-type transducers. Their characteristics vary depending on the particular loudspeaker model. Large magnetic structures, edge-wound voice coils, and high stiffness-to-mass cones enhance power handling and clean reproduction. The enclosures are ported designs (also called bass-reflex or vented) to improve low frequency efficiency and extend the low frequency response.
