Mackie MR8 Parts list
MR8
Monitor Series
The MR8 is the result of extensive research in
the development of new transducers and crossover
design. The result is a product with exceptional
del-ity, the ability to produce deep controlled bass
and extended high frequencies without sacricing
efciency.
The low-frequency 8" driver's low-mass, carbon
ber diaphragm remains extremely rigid at high power
levels, producing a more linear response and lower
distortion. The cone is tted with a durable foam
surround and treated to resist moisture. The highfrequency section features a constant directivity horn
with a built-in mechanical phase equalizer. The horn
is driven by a Ferrouid® cooled, 1" titanium dome
tweeter.
The system is nominally crossed over at 1.6kHz by
a 12 dB/octave network, which uses markedly lower
(than conventional) inductance values in series with
the woofer. This design reduces sound delays associated with high inductance values and provides excellent low frequency transient response.
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 MR8, as
a single unit or in arrays, using specially designed
accessory mounting hardware. The speaker system
is available in black or white (MR8W).
The MR8 is a part of Mackie Industrial’s Monitor
Series, which includes two-way constant directivity,
compact speakers in easily installed enclosures.

exclusive, one-time, NO FAULT repair policy in addition
