Enclosure Talk
Right on! You got yourself a shiny new AudioControl subwoofer, or maybe
two. After you're done admiring the quality workmanship and attention to
detail, you need to get 'er in a proper enclosure. Enclosure is just a fancy
name for a speaker box. Below are some tips you should consider before
buying or building an enclosure. If you're not into math, or have trouble
plugging in power tools, your best bet is to seek out a qualied AudioControl
dealer. They have the skills, experience and specialized tools to get the bass
bumpin' and they usually smell alright, too.
Sealed vs. Ported Enclosure
Aaahh... the age old question: Which is better, a sealed or ported enclosure?
The answer usually boils down to a few things; available space in the vehicle,
music listening preference and the speaker manufacturer's recommendation
for enclosure type. Below are a few characteristics of sealed and ported
enclosures:
Sealed Enclosures
Smaller enclosure size
Excellent transient response
Less output per watt, but punchier, tighter sound
Lower dynamic output
Ported/Vented Enclosure
Larger enclosure size
Extended low frequency response
More bass output per watt
Better dynamic output
If you have the space, we recommend a slot vented enclosure for the best
all-around bass experience.
Enclosure Size... It Matters
Once you decide on a sealed or ported enclosure, you can ne-tune the size
of the enclosure to t your vehicle space and listening habits. For both sealed
and ported enclosures, we list recommended size ranges, (MIN - IDEAL - MAX)
for each subwoofer size in the following pages. Whether buying pre-made
or designing and building a custom enclosure, try to stay within these
parameters for the best overall performance. Below is the eect enclosure size
has on the overall sound.
The MIN value is the smallest recommended enclosure
size. It provides the most compact size, but sacrices
some low bass response. It generally provides punchy, tight bass that is great
for Rock and Country music.
The IDEAL value is recommended for most listeners.
Excellent blend of low bass, with accurate and strong
overall output. Suited well for Pop and R&B music.
The MAX value is the largest recommended enclosure
size. It's big, but provides exceptional bass output.
Perfect for all you Hip Hop and EDM fans.

The Warranty
In just the same way as being covered in honey and thrown into a dark pit
full of hungry woodchucks, people are scared of warranties. Lots of ne print.
Months of waiting around. Well, fear no more. This warranty is designed to
make you rave about AudioControl. It’s a warranty that looks out for you and
your client, plus helps you resist the temptation to have your friend Sparky,
who’s “good with electronics,” try to repair your AudioControl product. So go
ahead, read this warranty, then register the information at www.audiocontrol.
com/product-registration and include your comments.
Our warranty has conditional conditions! “Conditional”doesn’t mean
anything ominous. The Federal Trade Commission tells all manufacturers to
use the term to indicate that certain conditions have to be met before they’ll
honor the warranty. If you meet all of these conditions, AudioControl will,
at its discretion, repair or replace any AudioControl speaker products that
exhibit defects in materials and/or workmanship for one (1) year from the
date you bought it. We will repair or replace it, at our option, during that time.
Here are the conditional conditions:
1. You must fully register your purchase within 15 days of the purchase date
by going to the AudioControl product registration page at:
www.audiocontrol.com/product-registration
Failure to register your product will negate the warranty.
2. You need to hold on to your sales receipt! All warranty service requires
original sales receipt documentation. The warranty only applies to
the original purchaser from an authorized AudioControl dealer. Note:
Products purchased from unauthorized dealers are not covered under
warranty.
3. The AudioControl speaker products must have originally been purchased
from an authorized AudioControl dealer. If an authorized AudioControl
dealer installs your AudioControl product, the warranty is extended to
two (2) years.
4. Our warranty covers AudioControl products that have been installed
according to the instructions in this manual.
5. You cannot let anyone who isn’t: (A) the AudioControl factory; or
(B) someone authorized in writing by AudioControl, service your
AudioControl product. If anyone other than (A), or (B) messes with your
AudioControl product, the warranty is void.
6. The warranty is void if the serial number is altered, defaced or removed,
or if your product has been used improperly. Now that may sound like a
big loophole, but here is what we mean by this: Unwarranted abuse is:
(A) physical damage (don’t use your product to pound in fence posts);
(B) improper connections (120 volts into the speaker terminals can fry
the poor thing). This is the best product we know how to build, but for
example, if you mount it to the front bumper of your car, drop it over
Niagara Falls, or use it for anchoring your boat, something will go wrong.
Assuming you conform to 1 through 6, and it really isn’t all that hard to do,
we get the option of xing your product, or replacing it with a new one, at our
discretion.
In the event that your product is out of warranty or not covered under our
warranty you may request to have any damage repaired at our normal“Out of
Warranty” repair cost.
Peace of Mind

Legalese
The warranty above is the only warranty issued by AudioControl. This
warranty gives you specic legal rights, and you may also have rights that
vary from state to state.
Promises of how well your AudioControl product will work are not implied by
this warranty. Other than what we’ve said we’ll do in this warranty, we have
no obligation, express or implied. We make no warranty of merchantability or
tness for any particular purpose. Also neither we nor anyone else who has
been involved in the development or manufacture of the unit will have any
liability of any incidental, consequential, special or punitive damages,
including but not limited to any lost prots or damage to other parts of your
system by hooking up to the unit (whether the claim is one for breach of
warranty, negligence of other tort, or any other kind of claim). Some states do
not allow limitations of consequential damages.
