User manual MACKIE MR5S DATASHEET

[. . . ] The high-frequency section features a 105° x 105° constant directivity horn with a built-in mechanical phase equalizer. The horn is driven by a Ferrofluid® cooled, 0. 75" soft dome tweeter. The system is nominally crossed over at 2. 5kHz by a 12 dB/octave network, which uses markedly lower (than conventional) inductance values in series with the woofer.

The low-frequency transducer shall be a cone type loudspeaker having a carbon fiber cone with a diameter of at least 5 inches (130mm). 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 1 inch in diameter and present a nominal 8-ohm load impedance to the crossover network. The high-frequency section shall consist of a constant directivity horn driven by a soft dome tweeter having a diameter of at least 0. 75 inches (19mm). Its voice coil shall be treated with Ferrofluid® to aid in cooling. It shall present a nominal 8-ohm load impedance to the crossover network. The constant directivity horn shall have an integral phase correcting mechanical equalizer. The system shall be crossed over by an internal, highlevel, passive network having a response of 12 dB/octave and equalization for the constant directivity horn. The nominal crossover frequency shall be 2. 5kHz. The low-pass section of the network shall have minimum inductance in series with the low-frequency driver. A dynamic high-frequency protection circuit based on a low-value, low-mass filament resistor shall limit the current available to the high-frequency driver. The crossover network shall present a nominal 4-ohm load impedance to the power amplifier. It shall be constructed using high density polystyrene and finished with black (or white), scratch resistant paint. It shall be trapezoidal in shape with 45° angled sides. A full size, detachable, perforated steel grille, finished in black (or white) scratch resistant paint shall be provided. At least 4 reinforced threaded metal sockets (3/8" and M6) for attaching optional mounting hardware shall be provided. [. . . ] 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.
