INTRODUCTION
About the MP41 Multi Purpose Speaker
Frequency Response
102-20kHz
The MTX MP41 may be the most comprehensive
loudspeaker design ever conceived. The unparalleled
application flexibility afforded by this design gives you the
freedom to listen to music almost anywhere and in just
about any possible configuration.

Features
•Balanced Dome Tweeter
Extended high frequency response is achieved through the
use of an integrated balanced dome tweeter. This particular
design offers the efficiency of a cone type tweeter with the
wide dispersion pattern of a dome. The tweeter is also
magnetically shielded to minimize color distortion of your TV
when used as a home theater system center channel or
front main speaker.

The mineral filled polypropylene cone and butyl rubber
surround of the MP41 are combined with a computer
optimized magnetically shielded motor structure and a long
wind voice coil to provide extended low bass response. The
woofer and tweeter have been designed to provide excellent
frequency response characteristics, both on and off axis,
across the majority of the audible frequency spectrum.
Specifications subject to change without notice.
•Weather Resistant Design
All of the material used in the construction of the Model
MP41 were chosen for their environmental stability as well
as their sonic characteristics.

Left/Center/Right Front Speaker Height

One of the most Important parameters for the
left/center/right/front speakers in a home theater system is
height. Figure 2 shows the ideal arrangement of the
speakers in relation to the viewing screen: all three
speakers are aligned on the same horizontal plane. This
establishes a firm image height when special audio effects
are panned from one side to the other, such as a speeding
car moving across the screen. When a large discontinuity
occurs between the heights of the center front channel and
the left/right front speakers, as depicted in Figure 3, the
visual image of the moving object becomes confused and
somewhat unnatural due to shifts in image height.

CENTER CHANNEL
Remove the B-Type end caps, brass thumb screws, and
aluminum mounting bracket. Replace the brass thumb
screws in each end of the cabinet and snap A-Type end
caps into place. Then simply place the self adhesive cabinet
feet in the appropriate locations to protect the MP41 cabinet
and whatever surface that it will sit on.
Typical Loudspeaker Placement
Figure 1 illustrates the most generally accepted speaker
locations for a home theater system. Although there are an
infinite number of set up options using Figure 1 as a
template will certainly provide a great starting point.
Experimentation with slightly different speaker locations may
provide improved performance in your specific listening
environment.
The front left and right speakers should form a 45 degree
triangle using the center seating position as the apex.
The surround speakers should be placed beside the
listening area, and pointed towards each other. It is also
recommended that the speakers be 2-3 feet above the
listeners head.

WIRING
Connecting the Speakers to Your System
Remove the B-Style end caps, brass thumb screws, and
aluminum mounting bracket. Replace the brass thumb
screws in each end of the cabinet and snap A-Type end
caps into place. Then simply place the self adhesive cabinet
feet in the appropriate locations to protect the MP41 cabinet
and whatever surface that it will sit on.
Though there are many sizes of speaker wire available.
MTX recommends using 18 gauge or heavier wire to
connect your loudspeakers to your amplifier or receiver.
Before cutting the speaker wire to the proper lengths, be
sure to leave an extra two or three feet of surplus wire, just
in case you have to move the components around. Using a
wire cutter or sharp knife, strip off about half an inch of
insulation from both ends. Twist the exposed wires to make
them easier to insert in the speaker terminals. Make sure
that you unplug your amplifier or receiver before proceeding
any further.
A-TYPE
CAP
When using the MP41 as a center channel or surround
speaker follow the hook-up directions included with your
surround processor.
It is essential that you connect your two speakers “in
phase”. To do so, first take note of the code used on the
speaker wire to differentiate between the two wires that run
through it.
To wire your speakers in phase, make sure the positive (+)
terminals on the back of your receiver are connected with
the red terminals on the back of your loudspeakers, and the
negative (-) terminals on the receiver are connected with
the black terminals on the speakers (see diagram). Note
that negative (-) terminals on the receiver may also be
marked “common” or “ground” (GND).
Be certain that no stray strands of wire cross from one
terminal to another on either speaker or receiver. This could
result in a damaging short.

PAINTING
MP41 CONFIGURATION GUIDE
FLOOR STAND
Carefully remove the spring clip on the back of the grill logo
and remove the logo. Mask the baffle area of the speaker
cabinet out to the grill mounting groove. If you are going to
mount the MP41 using the supplied wall bracket it is best to
also mask off the foam rubber bracket gaskets at the top
and bottom of the speaker cabinet. Almost any type of paint
can be used but best results will be had using a quick
drying enamel or lacquer spray paint. For best results
always follow the paint manufacturers recommendations for
proper application. After painting the cabinet, grill and
applicable end caps allow the paint to dry thoroughly.
Remove the B-Type end caps, brass thumb screws, and
aluminum mounting bracket. Replace the brass thumb
screws in the top of the cabinet and snap an A-Type end
cap into place. Then simply mount the MP52 to the
recommended Studio Tech S1 stands using a 1/4-20 1” long
hex head bolt. (Not Included)
