Mackie Monitor Series MR4 Specifications

Monitor Series
Careful acoustic design and the use of advanced
materials contribute to the exceptional music fidelity
and speech intelligibility exhibited by the Mackie
Industrial MR4/4T (black) and MR4W/4WT (white)
two-way speaker systems.
The low-frequency driver's carbon fiber diaphragm
remains extremely rigid at high power levels, produc-
ing a more linear response and lower distortion. The
cone is fitted with a durable foam surround and treated
to resist moisture. The high-frequency section features
a constant directivity horn with a built-in mechanical
phase equalizer. The horn is driven by a Ferrofluid
®
cooled, 0.5" Mylar dome tweeter.
The system is nominally crossed over at 4kHz by
a 12 dB/octave network, which uses markedly lower
(than conventional) inductance values in series with
the woofer. This design reduces sound delays associ-
ated with high inductance values and provides excel-
lent low frequency transient response. The high-pass
section is corrected for optimum performance of the
CD horn and is protected with a circuit based on a low-
value/low-mass filament resistor that smoothly limits
the power sent to the tweeter driver.
All components are housed in a vented enclosure
formed from semi-expanded polystyrene foam that is
extremely strong, lightweight and weather resistant.
Threaded metal sockets are molded into the cabinet to
facilitate quick, safe deployment of the MR4/4T, as a
single unit or in arrays, using specially designed acces-
sory mounting hardware.
The MR4/4T is a part of Mackie Industrial's Monitor
Series, which includes two-way constant directivity,
compact speakers in easily installed enclosures.
This Mackie Industrial product is covered by an
exclusive, one-time, NO FAULT repair policy in addition
to a five year limited warranty.
