APPENDIX - XLT41E and XLT48E

The XLT41E and XLT48E, in addition to being part of the XLTE Series, are available to Community Contractors and Distributors as part of Community’s CPL Loudspeaker Series. Their function as part of this series is to provide portable monitor systems compatible with permanent installations using CPL full-range loudspeakers and subwoofers. Because of certain more demanding requirements for permanent installations, additional XLT41E and XLT48E models are offered in the CPL Series with features that match those of other CPL products.

A. XLT41E and XLT48E Additional Models

The additional models are identical to the base model XLT41E-94B and XLT48E-94B in all respects, except for the availability of a 60° x 40° degree horn option, different enclosure finishes, and cloth covering on the grille, depending on enclosure finish.

Each XLT41E and XLT48E model has a suffix that defines the configuration of these features as listed in TABLE 8.
