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

long speaker cables.  
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 charac-  
teristics 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.  
In short, all the complex interconnected compo-  
nents 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 out-  
put 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...  
What is it? The Advantages...  
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.  
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 mass-  
loaded 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.  
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 nega-  
tive 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.  
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.

in the system.  
6. Start your signal source (tape deck, CD, DAW,  
or whatever), but leave the master volume  
control on your mixer or preamp down.  
7. Adjust the master volume on your mixer or  
preamp to a comfortably loud  
listening level.  
8. Slowly turn up the INPUT SENSITIVITY  
control on the back of the HRS150 to its  
fully clockwise position (NORMAL), or until  
you achieve a balance between the  
subwoofer and the other speakers in  
the system.  
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 INPUT SENSITIVITY  
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  
on the rear panel off  
(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 CROSS-  
OVER controls set to the center position (80 Hz).  
9. Enjoy the authoritative, commanding lows  
of the HRS150.

PLACEMENT  
Corner or Center Placement  
AN IMPORTANT NOTE  
ON HRS150 BASS  
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  
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 fre-  
quencies below about 100 Hz are  
certain frequencies.  
non-directional, it is also true that a lot of fac-  
tors 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:  
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 in-  
creased 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.  
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 re-  
modeling 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 reproduc-  
tion 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-of-  
phase 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 reinforce-  
ment 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 nar-  
row band near resonance, and then appears to  
be attenuated between resonances.  
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 cabi-  
net 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.

Play music with a good strong bass line and • Save the shipping box! You may need it  
crawl on the floor on your hands and knees until  
you find a spot where the bass sounds the best,  
with a smooth, tight response. Your ears need  
to be at the same height that the subwoofer’s  
driver will be when it is sitting on the floor. If  
you have access to a real-time analyzer (RTA),  
play pink noise over the system and use the  
RTA to find a location that exhibits the flatest  
bass response. Once you’ve found the place  
where the bass sounds the best, put the  
someday, and you don’t want to have to pay  
for another one.

A Few Words About THX™ pm3™  
Certification  
Nearly two decades ago, George Lucas  
turned a passion for great sound into the  
world’s most accepted and trusted solution for  
achieving it. The standard was named THX  
(for Tomlinson Holman, who developed the  
THX Sound System when he was the research  
and technical director at Lucasfilm Ltd.™ in  
the early 80s), and today, with hundreds of  
thousands of home theater customers and  
more than 3000 THX Certified movie theaters  
enjoying its benefits, the THX name has be-  
come nothing short of legendary. Simply put:  
when it comes to premium sound, no other  
name so closely defines ‘quality’ for millions of  
movie-goers and home theater enthusiasts alike.  
Today, a new landscape is emerging. A land-  
scape comprised of hundreds of small,  
professional multi-channel facilities, whose  
need for differentiation, expert technical and  
marketing support, and a true, multi-channel  
standard is becoming a competitive fact of life.  
Again, THX has a singular solution and this  
time it’s called THX pm3 Certification.  
All facilities involved with mixing and/or moni-  
toring of multi-channel material should have the  
option to use pm3. THX pm3 Certification is ideal  
for DVD mastering, sweetening, and mixing; and  
is also perfect for facilities doing work in broad-  
cast, music, or multi-media applications.  
subwoofer there and it should sound just as  
good from your listening position.  
Polarity  
The setting of the polarity switch can affect  
how the low frequencies sound in relation to the  
main speakers. Listen to bass-heavy music with  
the polarity switch in and out. In one position  
the low frequencies should sound full, while in  
the other position they may sound hollow and  
thin. Choose the position that yields the fullest  
low-frequency sound.  
Feel free to experiment  
In many respects, every room is unique in  
terms of its acoustics. Even after you’ve placed  
your subwoofer where you think it’ll sound  
best, try moving it around. You might be pleas-  
antly surprised.  
Additional Tidbits of Wisdom  
• Avoid using EQ to compensate for dips in  
the frequency response caused by room  
modes. It is better to place the subwoofer in  
a position where dips are minimized and  
use the EQ to smooth out any peaks.  
• Provide at least six inches clearance  
around the heatsink to allow air to get at it.  
• Provide at least three feet clearance from a  
TV, computer monitor, or any form of  
HRS150 THX pm3 Certification  
Anyone seeking THX Certification for their  
studio, or striving to maintain THX standards,  
can use the HRS150s and rest assured that  
their facility is in full compliance.  
magnetic media (video and audio recording  
tapes, computer disks, etc.), to prevent the  
HR150’s powerful magnet from distorting the  
video screen or erasing the magnetic media.  
• When you shut down your equipment, turn  
off the HRS150 powered subwoofer first  
(and any other powered speakers in the  
system) to prevent thumps and other  
noises generated by any upstream equip-  
ment from coming out the speakers. When  
powering up, turn on the powered speakers  
and subwoofer last.

PROTECTION CIRCUITS CONNECTIONS  
There are several protection mechanisms  
designed into the HRS150 to safeguard the  
loudspeaker and amplifier from inadvertent  
damage.  
Input and Output Signal Wiring  
You should use high-quality, shielded cable  
to connect the signal source to the LEFT and  
RIGHT IN  
and OUT  
jacks on the HRS150.  
• Foil shielded cables, such as Belden 8451,  
8761, or 9501 are commonly used for  
studio wiring.  
Peak Limiter  
A peak limiter is located at the input to the  
power amplifier section. It monitors both the  
amplifier output signal and the power supply  
voltages to guard against clipping and over-  
loading the amplifier. This allows for loud and  
punchy bass performance without distortion,  
ensuring long-term reliability.  
• Microphone cables work well.  
• The better the shield, the better the  
immunity from externally induced noise  
(like EMI and RFI). Route the cable away  
from AC power cords and outlets. These are  
common sources for hum in an audio signal.  
Wall warts and line lumps are especially  
insidious hum inducers!  
Thermal Protect  
You can purchase quality cables from your  
Mackie dealer.  
All amplifiers produce heat. The HRS150  
is designed to be efficient both electrically  
and thermally.  
• If for some reason the heatsink or power  
transformer gets too hot, a thermal switch  
activates, placing the HRS150 into Standby  
mode.  
• Should this happen, make sure that airflow  
to the rear of the cabinet is not restricted.  
• When the heatsink or power transformer  
cools down to a safe temperature, the switch  
resets and normal operation resumes.  
• In certain home theater applications, it  
may be necessary to connect the speaker  
outputs from a stereo receiver to the inputs  
of the HRS150s, if the receiver doesn’t have  
preamp outputs or other line-level output  
connections.  
CAUTION: Do not attempt  
to connect a speaker output  
directly to the input of the  
HRS150! Speaker levels are  
much higher than line  
Note: The POWER LED remains lit if the ther-  
mal protection circuit is activated.  
levels and can damage the input circuitry  
in the HRS150.  
You can, however, insert a speaker-level to  
line-level signal attenuator between the  
receiver’s speaker output and the HRS150’s  
input. Your Mackie dealer may be able to  
help you find one, or you can build your  
own. Contact our tech support department  
for more information.

SERVICE INFO  
Bad Sound  
Details concerning Warranty Service are  
spelled out on the Warranty Card included with  
your subwoofer (if it’s missing, let us know and  
we’ll rush one to you).  
If you think your subwoofer has a problem,  
please do everything you can to confirm it before  
calling for service, including reading through  
the following Troubleshooting section. Doing  
so might save you from deprivation of your  
monitor and the associated suffering.  
Of all Mackie products returned for service  
(which is hardly any at all), roughly 50% are  
coded “CND” — Could Not Duplicate, which  
usually means the problem lay somewhere else  
in the system. These may sound obvious to you,  
but here are some things you can check:  
• Is the input connector plugged completely  
into the jack?  
• Is it loud and distorted? Reduce the signal  
level at the mixer.  
• If possible, listen to the signal source with  
headphones plugged into the preamp stage.  
If it sounds bad there, it’s not the subwoofer.  
• Too much bass or not enough bass? Move  
around the room and see if the bass  
response changes. It’s possible your  
listening position coincides with a room  
mode where the low frequencies either  
become exaggerated or nulled. If so, try  
moving the subwoofer to a different  
position, or moving your listening position.  
• If the signal source is an LFE or subwoofer  
output from a home theater preamplier,  
make sure the signal level for the low-  
frequency output is turned up in the  
preamp. If you have connected the low-  
frequency signal to the LEFT (and RIGHT)  
INput, make sure the FILTER BYPASSED  
switch is pushed in.  
Troubleshooting  
No Power  
• Our favorite question: Is it plugged in?  
• Make sure the power cord is securely  
seated in the IEC socket  
all the way into the AC outlet.  
and plugged  
• Make sure the AC outlet is live (check with  
a tester or lamp).  
Noise/Hum/Buzz  
• Check the signal cable between the mixer/  
preamp and the subwoofer. Make sure all  
connections are secure. These problems  
usually produce crackling noises, hum, or buzz.  
• If connecting an unbalanced output to the  
HRS150 balanced input, make sure the  
shield is connected to both pins 1 and 3 on  
the XLR.  
• If a CATV cable is connected to the system,  
try disconnecting it. If the hum goes away,  
call your cable carrier to check for proper  
grounding of the cable.  
• Make sure the signal cable is not routed  
near AC cables, power transformers, or  
other EMI sources (including wall warts  
and line lumps!). These sources usually  
produce hum.  
• Is there a light dimmer or other triac-based  
device on the same AC circuit as the  
monitor? Dimmers cause buzzing noises.  
Use an AC line filter or plug the subwoofer  
into a different AC circuit.  
• If possible, listen to the signal source with  
headphones plugged in. If it sounds noisy  
there, it’s not the subwoofer.  
• Is the POWER  
switch on the rear panel  
in the ON position?  
• Is the POWER  
LED or BYPASSED  
LED on the rear panel illuminated? If not,  
make sure the AC outlet is live. If so, refer  
to “No Sound” below.  
• If the POWER LED or BYPASSED  
LED  
is not illuminated, and you are certain that  
the AC outlet is live, it will be necessary to  
have the HRS150 serviced. There are no  
user-serviceable parts inside. Refer to  
“Repair” at the end of this section to find  
out how to proceed.  
No Sound  
• Is the POWER  
LED or BYPASSED  
LED on the rear panel illuminated? If not,  
refer to “No Power” above.  
• Is the INPUT SENSITIVITY control  
turned up?  
• Is the signal source turned up? Make sure  
the signal level from the mixing console (or  
whatever device immediately precedes the  
subwoofer) is high enough to produce sound.

The text is a compilation based on input  
from a number of sources including Cam Jones,  
Terry Wetherbee, Marcelo Vercelli, and Keith  
Olsen. Dave Franzwa and Jayney Wallick pro-  
duced this manual using the following tools:  
Initially written in Microsoft® Word 98 for  
the Macintosh, the text was imported into  
Adobe PageMaker® 6.5. Illustrations were pro-  
duced in Adobe Illustrator® 9.0. Most of the  
work was done on two Power Macintosh® G4  
computers with Mac OS 9.1 installed. These  
machines have PowerPC G4 processors; 384MB  
of RAM; a 10GB, and a 28.62GB internal hard  
drive, respectively; an internal Matshita DVD-  
ROM drive, and an internal Sony CD-RW drive,  
respectively; and one internal Iomega Zip™  
Drive for backup and transfer of files. A  
Hewlett-Packard LaserJet 5000N with a duplex  
tray installed (to save trees) was used to print  
out laser proofs. PDF files were created with  
Acrobat™ Distiller 4.0 and 5.0, respectively. A  
wind-driven open window provided much-  
needed relief as the production deadline  
approached. This entire manual was written  
and produced while sitting in a comfy chair,  
which was actually more comfy than the one  
used while producing the HR824 manual.

D. To obtain factory service:  
1. Call Mackie at 800/258-6883, 8AM to 5PM  
Monday through Friday (Pacific Time) to get a  
Return Authorization (RA). Products returned  
without an RA number will be refused.  
2. Pack the product in its original shipping car-  
ton. If you do not have the carton, just ask for  
one when you get your RA number, and we’ll  
send a shipping carton out promptly. More infor-  
mation on packing can be found in the Service  
section of this manual. Do not use “packing pea-  
nuts,” shredded newspapers, or other material  
with small particles, old underwear, or socks.  
Please seal the Mackie product in a plastic bag.  
3. Also include a note explaining exactly how to  
duplicate the problem, a copy of the sales receipt  
with price and date showing, and your return  
street address (no P.O. boxes or route numbers,  
please!). If we cannot duplicate the problem at  
the Mackie Factory or establish the starting date  
of your Limited Warranty, we may, at our option,  
charge for service time.  
4. Ship the product in its original shipping car-  
ton, freight prepaid to:  
Mackie Designs  
Service Department

IMPORTANT: Make sure that the RA number is  
plainly written on the shipping carton.  
F. Mackie reserves the right to inspect any products  
that may be the subject of any warranty claims be-  
fore repair or replacement is carried out. Mackie and

tion, require proof of the original date of purchase in  
the form of a dated copy of the original dealer’s in-  
voice or sales receipt. Final determination of
