User manual MACKIE MSW8 DATASHEET

[. . . ] MONITOR Series The Monitor MSW8 subwoofer was expressly designed to complement the Monitor MR8. Alternate satellite speakers, differing from the MR8 in sensitivity and/or impedance, may be used with the MSW8, by making use of a switch located on the terminal plate. [. . . ] It is coated with scratch resistant, matte black PVC with the exception of the attractively contoured baffle that is paint coated to facilitate repainting.

The low frequency transducer shall be a cone type loudspeaker having a diameter of at least 12 inches (300mm). The cone shall be fitted with a high compliance foam surround and treated to resist moisture. It shall have a voice coil that is at least 3 inches in diameter and present a nominal impedance load of 8 to the crossover networks. The system shall be crossed over by an internal, high-level, passive network having a response of 12dB/octave. The crossover network shall present, at the connectors, a high-pass output at 120Hz for the purpose of connecting a full range satellite loudspeaker. It shall be constructed using high density particle board and finished with black, scratch resistant PVC. The overall dimensions of the enclosure shall not exceed (HxWxD) 31. 52" x 11. 74" x 20. 01" (800mm x 298mm x 508mm). [. . . ] New material, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current Mackie Industrial product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
