Performance Features
• High Performance Drivers
Each HT30 enclosure contains one 5-5/8 inch Low Frequency Driver and two 2-3/4 inch Midrange/Tweeter
Drivers arranged in an Antiphase Dipole, Mirror Image
configuration.
• Special Crossover
At frequencies below 1000Hz the Low Frequency Driver
operates in-phase; above 1000Hz the Midrange/Tweeters
operate out-of-phase thus providing the desired diffused
surround effect. The Low Frequency Driver crosses over at
a 12dB per octave rate and the Midrange/Tweeter Drivers
cross over at a 12dB per octave rate.
Important Information
1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected to
the HT30 Loudspeaker System.
2. The HT30’s built-in speaker protection incorporates
an automatic resetting solid-state device in the crossover network. If there is a reduction in output volume
the Protection Device may have activated. This device
will automatically reset when the volume level of the
amplifier is reduced significantly and kept low until the
output of the Loudspeaker returns to normal.
3. When discarding the unit, comply with local rules or
regulations. Batteries should never be thrown
away or incinerated but disposed of in accordance with the local regulations concerning
battery disposal.
4. For additional information on the HT30 and
other McIntosh Products please visit the McIntosh Web Site at www.mcintoshlabs.com.
• High Efficiency
The Loudspeaker Elements used in the HT30 Loudspeaker
System have also been designed for high efficiency. As a
result any McIntosh Power Amplifier, even our smallest,
will provide satisfying room filling sound, yet they can be
used with amplifiers up to 200 watts.
• Minimum Visual Impact
The HT30s offer a unique solution to the problem of integrating superb surround sound into a room without drawing attention to the Loudspeakers. The removable metal
grilles can be custom painted or wallpapered to perfectly
match your decor.
• High Power Handling
The Loudspeaker Elements and Crossover Components of
the HT30 are all chosen for use with amplifiers up to 200
watts. The automatic resetting solid-state device protects
the Loudspeaker from possible damage.
• Sealed Enclosure
A sealed solidly braced enclosure is used for superior
sound and freedom from bleeding into adjacent rooms.
• Gold Plated Input Connectors
The HT30 input connectors are gold plated for superior
corrosion resistance and high electrical conductivity.

Installation
Location in the Room
The McIntosh HT30 Loudspeaker is specifically optimized
for Surround Sound Applications. The Loudspeakers are
intentionally designed to create a very diffused sound
field. The HT30 uses a dipolar radiation pattern to achieve
this performance. A dipole Loudspeaker radiates sound
both forward and backward, with an acoustic null located
at the horizontal center of the enclosure. If a dipole Loudspeaker is placed such that the listeners are seated within
the null, they will hear surround sound only after it has
been randomly reflected off the walls of the room. The
listener will perceive no specific direction for Surround
Sound. Refer to figure 1.
This is perfectly acceptable and can be achieved by mounting the HT30 Loudspeakers so that the listener is not in the
null of the system but 30 degrees forward or backward of
the null. The selected volume level of the surround speakers will also play a major role in determining whether the
surround effects are obvious or subtle.
In very large installations, more than one pair of HT30
Loudspeakers can be used. This would apply in home
installations with two, three or more rows of theater style
seating. For such installations install a pair of HT30 systems in the normal way adjacent to the first seating row.
For every third or fourth row behind, install an additional
pair. Refer to figure 2.
The HT30 achieves this dipolar radiation via indepen-
Figure 1
dent forward and rearward firing Loudspeaker Drivers
connected in antiphase to assure a cancellation null at
right angles. Complete mirror symmetry of forward and
rearward firing faces of the HT30 assure a deep broadband
null of all directional frequencies for any position on the
dividing plane of the system. This includes upward and
downward elevation angles and allows the HT30 to be
mounted in a variety of heights on the side wall (or even on
the ceiling), as long as the listener is on the dividing plane
between left and right halves of the HT30.
Varying the Sound Field
Some listeners will want a less diffused and more directional effect from their surround Loudspeakers. To them,
sound panning off screen, such as jets flying overhead, are
more important than the creation of a diffused sound field.

Installation
The HT30 Loudspeaker System may be installed by one
person, however two people will add to the safe handling during installation. Follow the instructions below
for unpacking and assembly. It is recommended that the
Professionals at your McIntosh Dealer, who are skilled in
all aspects of installation and operation, install the HT30
Loudspeaker System and any associated audio equipment.
The HT30 Loudspeaker System is a mirror-image, dipole
design with the system connected out of phase with each
other and identified as HT30 Left and HT30 Right Louspeakers. The pair facing forward toward the viewing
screen must be in phase with the front Loudspeakers. Refer
to page 5 for additional information as to which HT30
(Left Loudspeaker or Right Loudspeaker) to use at a given
location in the room. Also refer to page 7 for connection
information.
HT30-OW On Wall Mount
1. Remove the front grille from the HT30-OW by gently
pulling it forward. Refer to figure 3.
2. Position the HT30-OW on the wall where you wish to
Figure 3
mount it. Using the supplied template, mark on the wall
the locations for the four mounting screws.
3. Install using four suitable wall mounting fasteners and
insert the screws partially so they extend out far enough
to clear the thickness of the HT30-OW back panel.
Note: Each fastener must have a total of 20 pounds or more
of load capacity.
4. Position the HT30-OW over the screws and slide it
down so the screws fit in the mounting slots. Tighten the
screws.
5. Replace the HT30-OW grille.
Note: If the HT30-OW is ceiling mounted, additional
fasteners may be required to secure the grille to the
Loudspeaker.
6
HT30-IW In Wall Mount
1. Determine the location where you wish the HT30-IW
Loudspeakers to be installed in the wall using the supplied template. Refer to figure 4.
Installation, con’t
7. Place the trim frame in position over the HT30-IW and
secure it to the Loudspeaker system using the supplied
flat head screws. Use the mounting holes at the top and
bottom edges of the frame.
Notes: 1. The holes on the sides of the frame are not used.
2. If the wall thickness is greater than 1/2 inch (1.27
cm), longer screws might be required to secure the
trim frame.
8. Carefully press the grille into the trim frame, so the
foam gasket holds the grille in position.
Note: If the HT30-IW is ceiling mounted, additional
fasteners may be required to secure the grille to the
Loudspeaker.
Figure 4
2. Cut a 13-5/8 inch (34.61 cm) square hole centered in the
desired position. The location should be centered between the wall studs since the HT30-IW will take most
of the space, with just a small clearance on each side.
Note: There must be no obstructions within 1 inch (2.54cm)
of the cutout on the top and bottom. This is to provide
clearance for the slide fasteners to fit behind the wall
panel. The area behind the HT30-IW must be free
of any wires, cables or other obstructions since the
speaker depth is 3-15/16 inches (10.0cm), and may fill
the entire space between the walls.
3. Remove the front trim frame and grille.
Note: If the wall studs are 2 x 6, it may be desirable to have
the trim frame installed loosely on the HT30-IW at
this time to prevent the HT30-IW from falling down
inside the wall.
4. Proceed to page 7 for connection information and then
perform step 5 below.
5. Carefully slide the HT30-IW into the wall cutout.
6. Loosen the round head screws on the four slide wall
fasteners. Slide the fasteners up and down so they fit
behind the wall to hold the HT30-IW in place and then
tighten the screws.

How to Connect the Loudspeaker
Caution: The AC Power Cord should not be connected to the
Power Amplifier until after the Loudspeaker Connections have been made. Failure to observe this
could result in Electric Shock.
When connecting HT30 Loudspeakers to an amplifier
it is very important to use cables of adequate size, so there
is little to no power loss in the cables. The size is specified
in Gauge Numbers or AWG (American Wire Gauge). The
smaller the Gauge number, the larger the wire size:

1. Prepare Loudspeaker cables by choosing one of the
methods below:
Bare wire cable ends:
Carefully remove sufficient insulation from the cable
ends, refer to figures 5, 6 & 7. If the cable is stranded, carefully twist the strands together as tightly as
possible.

How to Connect the Loudspeaker
3. Connect a Loudspeaker cable from the HT30 (-) Bind-
ing Post to the (-) (4Ω) Binding Post of the Power
Amplifier.
Note: It is important to maintain the correct polarity at
both ends of the Loudspeaker cables.
4. Connect a Loudspeaker cable from the HT30 (+) Bind-
ing Post to the (+) (4Ω) Binding Post of the Power
Amplifier.
5. Tighten all of the Loudspeaker and Amplifier Binding
Posts.

Note: If desired, the twisted ends can be tinned with
solder to keep the strands together or attach
spade lugs.
Spade lug or prepared wire connection:
Insert the spade lug connector or prepared section
of the cable end into the terminal side access hole,
and tighten the terminal cap until the cable is firmly
clamped into the terminal so the wires cannot slip
out. Refer to figures 8, 9 & 10.
2. Based on the information contained in “Installing the
Loudspeaker” on page 5 and the Identification Label
located on the HT30 Loudspeaker (Left or Right),
determine the correct Loudspeaker to use for the given
location in the room.
