Congratulations on choosing NuTone loudspeakers! Great
care has been taken in their design, choice of material and
manufacture to maximize their performance at affordable
cost. When used individually with other 8 Ohm stereo
speakers in any 8 Ohm stereo amplifier system or in
combination with other NuTone 8 Ohm stereo speakers in
the “MS” series, they will provide years of excellent,
balanced and distortion-free listening pleasure.
INTRODUCTION
The MS-625 and MS-626 are two-way ceiling speakers.
MS-625 consists of a 5

MS-626 consists of a 6
1

2
" woofer with polymica cone with
butyl rubber surround and a
3

4
" Titanium dome tweeter with
Neodymium magnet and is the premium product in this
series, specifically designed to reproduce music and speech
in an exceptionally clear, crisp manner.
Two of these speakers can be used as front or rear channel
speakers in a surround sound system. Multiple speakers can
also be used for providing background or secondary music.
These speakers are designed for wall or ceiling mounting.
When mounted on ceilings, their round shape makes them
unobtrusive since they blend easily with other electrical
fixtures, which are normally round in shape. They are also
ideally suited for mounting on irregularly shaped walls or
cathedral type ceilings.
NuTone SENSONIC™ SURROUND SOUND Ceiling
Speakers are acoustically matched to other stereo speakers
in the “MS” series. A well-balanced home theater system can
be built using the optimally-engineered speaker components.
The “MS” series includes a variety of two-way and three-way
in-wall speakers, center channel speaker, sub-woofer, and
two-way indoor/outdoor speakers to complete a system.
SWIVEL DOME TWEETER
Unlike low frequencies, high frequencies are highly
directional. This means that you should be almost directly in
front of the tweeter that reproduces the high frequencies to
hear them well. Since in practice the ceiling speaker is likely
to be installed in an area not directly overlooking the
listening area, NuTone ceiling speakers have a tweeter
which can be swiveled 360° on its axis at an angle of 15° up
or down with respect to its surface. This ensures that every
tone in the music is heard clearly no matter where the
speaker is installed.
INSTALLATION
You can mount the ceiling speaker MS-625 or MS-626 easily
since they do not require rough-ins. Refer to Figure 1. Using
the template provided, cut a hole in the ceiling. Make sure
the tabs on the mounting bosses are facing inward. Remove
the grille carefully using a screwdriver, taking care to ensure
that it is not damaged, and place it aside. Unscrew the four
screws on the face of the speaker until they are about
3
⁄
4
of
the way out.
If the grille vibrates, you may apply a small amount of the
black acoustic damping material (packed with the speaker in
a small plastic bag).
Connecting the ceiling speaker to your amplifier or A/V
receiver is simple. Make sure the system is off. Refer to
Table 1 for choosing proper gauge wire, which depends on
the distance between the speaker and the amplifier/receiver.
The lower the gauge, the thicker the wire:
Use oxygen-free speaker cable. Strip about
1
⁄
2
" of insulation
from the wire at each end. Connect the wire to “RED” (+)
terminals of the speaker and the amplifier/receiver. Make sure
that the same wire goes from the “RED” (+) terminal on your
TV or amplifier/receiver to the “RED” (+) terminal on the
speaker. The “BLACK” (-) terminal of the speaker is connected
to the “BLACK” (-) terminal of the amplifier/receiver.
For making connection, simply press the lever on the terminal.
Push the wire in the slot and release the lever.
