Mackie MR6T Parts list

Monitor Series

Compact Full-Range Speaker

MR6T

SPEAKER

■ The MR6T is a compact full-range speaker that

Zcombines excellent intelligibility with high efficiency
and power handling.

■ The single 6.3" driver is an extended range, dual

cone design that achieves wide bandwidth with single
source coherency. The cone is fitted with a durable
foam surround and treated to resist moisture.

■ The speaker enclosure is a vented design, formed

from high density polystyrene that is extremely strong,
lightweight and weather resistant. Threaded metal
sockets are molded into the cabinet to facilitate quick,
safe, deployment of the MR6T, as a single unit or in
clusters, using specially designed accessory mounting
hardware. Available in black or white (MR6WT).

■ The MR6T 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.

Architects’ and Engineers’ Specifications

The loudspeaker system shall be self-contained and
consist of the following components: (1) a dual cone, full
range driver; (2) a constant voltage transformer; (3) a vented
enclosure.

The full-range transducer shall be a dual cone type
loudspeaker having a cone with a diameter of at least 6.3
inches (160mm). It shall present a nominal impedance load

of 4Ω to the constant voltage transformer or power amplifier.

The constant voltage transformer shall have multiple
power taps at 10, 25, and 50 Watts. It shall also have voltage
taps at 25, 50, 70 and 100V. Two detented rotary switches
shall be provided on the input panel to adjust the power and
voltage taps of the transformer. The voltage tap switch shall
have a position to bypass the transformer and allow the

loudspeaker to present a 4Ω load to a directly coupled

power amplifier.

The enclosure shall be a vented design. 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 for attaching optional mounting hardware offered by
the manufacturer shall be provided. The overall dimensions of
the enclosure shall not exceed (HxWxD) 11.82" x 8.39" x

8.96" (300mm x 213mm x 227.6mm). The total weight of the
loudspeaker shall not exceed 15lbs. (6.8kg). Connections to
the loudspeaker shall be two color-coded, spring-loaded
push connectors.

The loudspeaker system shall have an overall frequency
response of at least 70Hz–18kHz when measured to –10dB
and at least 200Hz–15kHz when measured to –3dB. It shall
have a nominal average coverage pattern of at least 90° hori­zontal by 90° vertical to –6dB when measured between
800Hz and 16kHz. Calculated 1W/1m sensitivity shall be at
least 95dB when measured in the far field between 300Hz
and 3kHz. Maximum SPL shall be at least 118dB at 1m. The
loudspeaker shall be rated for continuous operation at 50W
IEC with 200W peaks.

The two-way loudspeaker system shall be a model MR6T
(MR6WT - white) manufactured by Mackie Industrial.
