Lend Me Your Ears
Exposure to extremely high noise
levels may cause permanent hearing
loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss, but nearly everyone will lose
some hearing if exposed to sufficiently
intense noise for a period of time. The U.S.
Government’s Occupational Safety and Health Administration (OSHA) has specified the permissible
noise level exposures shown in this chart.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club
692
4 95 Subway Train
397
2 100 Very loud classical music
1.5 102
1 105 Patrice screaming at Ron about deadlines
0.5 110
0.25 or less 115 Loudest parts at a rock concert
According to OSHA, any exposure in excess of
these permissible limits could result in some hearing loss. To ensure against potentially dangerous
exposure to high sound-pressure levels, it is recommended that all persons exposed to equipment
capable of producing these levels use hearing protectors while this unit is in operation. Ear plugs or
protectors in the ear canals or over the ears must
be worn when operating this amplification system
in order to prevent a permanent hearing loss if
exposure is in excess of the limits set forth here.

INTRODUCTION
Thank you for choosing Mackie Designs’
HRS150 Powered Subwoofer. We realize that
monitors are a critically important tool whether
your application is studio recording, audio/video
post production, hi-fi, or home theater, and the use
of a subwoofer not only improves low-frequency
accuracy for stereo monitoring and playback, but is
absolutely necessary for surround sound applications.
The HRS150 complements our line of studio
reference monitors and, like our HR824 and HR624,
meets all THX™ requirements for mixing and
monitoring multi-channel programs.
In order to achieve a seamless integration between
the subwoofer and the main speakers in the system,
speaker placement is very important. The characteristics of the room and the location of the speakers,
including the subwoofer, relative to the walls and
your listening position can have a drastic effect on
the accuracy of the sound. We’ve provided a section
on positioning the subwoofers, offering tips on how to
find the best placement for your particular application.
What is it? The Advantages...
The HRS150 is a high-resolution powered
subwoofer employing an internal variable 4th-order
Linkwitz-Riley crossover system with a down-firing
RCF Precision 15“ woofer and two side-firing massloaded passive radiators. Whew! There are many
benefits to integrating an active crossover, power
amplifier, and drivers into a single cabinet, and
we’ve taken full advantage of these benefits in the
design of the HRS150.
• The crossover point is variable so that the high-
pass output can be programmed to match the
frequencies the main speakers are best able to
reproduce.
Part No. 0006805 Rev. B 5/03
©2003 Mackie Designs Inc. All Rights Reserved.
• The amplifier is designed to provide maximum
acoustic output from the speaker, yet minimize
the danger of speaker damage due to overdriving.
• The connecting wire between the amplifier
output and the low-frequency driver is kept to an
absolute minimum, so the damping factor of the
amplifier isn’t compromised by the resistance of
long speaker cables.
In short, all the complex interconnected components in the system are designed to work in harmony
with each other to produce the best possible sound.
The Transducers...
The subwoofer features a bottom-firing 15-inch
die-cast frame woofer and a 15-inch passive radiator
in the front.
The unique passive radiator design provides a
smooth response down to 19 Hz—an astounding
accomplishment for a cabinet of this size! And since
the radiator is complementing and adding to the output at the lowest frequencies, there is very little
distortion generated from the woofer because its cone
movement stays well within its maximum excursion.
The Cabinet...
The cabinet is made of black oak veneered MDF
wood. Extensive internal bracing further increases
the strength and rigidity (stiffness) of the box.
The box is packed with an adiabatic polyester-fill
material to absorb internal reflections and dampen
standing waves.
FR Series Power Amplifiers...
What better way to power the subwoofer than
with our acclaimed FR Series “Fast Recovery” power
amplifiers. Our Fast Recovery design uses low negative feedback, yet allows the amplifier to maintain low
distortion and stability even when driven into clipping.
The low-frequency amplifier produces up to 950
watts continuous (1050 watts peak) before clipping.

QUICK START
We realize that you can’t
wait to hook up your new
Mackie Designs HRS150
High Resolution Powered
Subwoofer and try it out.
Nevertheless, please take the time to read this
page NOW, and the rest can wait until you’re
good and ready.
The HRS150 has its own built-in power am-
plifier. You should turn the
control on the back of the cabinet down
(fully counterclockwise) before turning on the
HRS150 for the first time. Also be sure to set
the power switch
(down). This will prevent you from accidentally
connecting a hot signal source to the subwoofer
and getting a rude surprise.
There are a number of other settings you
can make on the back of the HRS150, and you
can read about them later on in this manual so
you really know what they do. For now, just
leave all the switches out, and the
controls set to the center position (

PLACEMENT
AN IMPORTANT NOTE
ON HRS150 BASS
RESPONSE AND YOUR
CONTROL ROOM OR
LISTENING ROOM
You’ve heard it before. “Low-frequencies are
non-directional, so it doesn’t matter where you
place the subwoofer.” Although it is true that frequencies below about 100 Hz are
non-directional, it is also true that a lot of factors can conspire to thwart the HRS150’s
extended low frequency — including room
shape, room volume, and acoustical treatment.
This is not a cop-out or an apology. It’s plain
old physics in action. Here are some tips to help
you find the best placement for your HRS150
and optimize the low-frequency response in
your particular room. Consider the following:
Room acoustics and bass-handling ability
Nobody likes to buy a subwoofer and a new
set of speakers and then be told that they
should spend extra bucks on bass traps or a remodeling job. But the simple fact is, “standard”
rooms, i.e., rectangular rooms in conventional
business or residential structures, are rarely if
ever conducive to optimal low bass reproduction without some modifications.
However, understanding what can cause
degradation of the low-frequency response in
a room can help in choosing a location that
can minimize the problems associated with
poor bass response most notably interference
and resonance.
Interference is caused when the reflected
wave from the surrounding walls arrive out-ofphase with the direct sound. This can weaken
or even cancel the sound. Keeping the distance
between the subwoofer driver and any adjacent
walls no longer than 1/8 of a wavelength (20 in.
or 51 cm at 80 Hz) can minimize interference.
Room resonance is caused by the reinforcement of certain frequencies between 20 Hz and
200 Hz, which creates “standing waves” or
room modes. These resonant frequencies are
determined by the dimensions of the room.
The bass response is sharply boosted for a narrow band near resonance, and then appears to
be attenuated between resonances.
Corner or Center Placement
Placing the subwoofer in a corner (corner
loading) excites the most room modes in the
room, which tends to smooth the individual
peaks and dips caused by each standing wave.
Moving the subwoofer outward from the corner
along the wall results in fewer standing waves,
but may result in noticeable peaks at
certain frequencies.
Some people prefer to place the subwoofer
between the left and right main speakers, so
that all the sound is coming from the same
plane. Some prefer to use two subwoofers and
place one with the left speaker and the other
with the right speaker. The Master Out/Slave
In connections on the HRS150 allow you to do
this quite easily.
Another benefit of corner placement is increased efficiency and lower distortion. The
energy that is reflected off the walls reinforces
the direct sound, putting less of a demand on
the power amplifier to reach higher sound
pressure levels.
It is important that the corner has good
structural strength, or the low-frequency energy
can cause rattling and other distracting vibrations.
Experiment with the orientation of the
subwoofer. The driver in the HRS150 faces
downward toward the floor while the passive
radiators face out the sides. It may be helpful
to play steady-state tones or pink noise while a
partner moves the subwoofer (perhaps on a
small wheeled cart), to make it easier to hear
the differences in the sound as the changes in
placement and orientation are made.
Principle of Reciprocity
One trick that has been used successfully to
find the best location for a subwoofer is placing
the subwoofer in your listening position. The
principle of reciprocity says that you can find
the best location for the subwoofer by switching
places between the listening position and the
subwoofer position. It is important that the cabinet be raised off the ground and at the same level
as your ears. If that’s not possible, at least put the
subwoofer in the same location as your listening
position to achieve a close approximation.
