Set-Up
Avoid placing the subwoofer
halfway between the front
and back walls. Avoid sitting
there as well.
Corner and nearfield
placement usually sound best.

Step 1: Unpacking
Before unpacking, inspect the carton for puncture holes, crushed corners, etc. Take photos of any potential
shipping damage before proceeding to unpack. Take note of which corner or wall the damage is on so you
can check the corner/side of the subwoofer nearest the external damage.
This subwoofer is very heavy. Be sure to get someone to help you unpack. If you have a hard floor, unpack
the subwoofer on a throw rug or blanket to avoid unwanted scuffing or scratching. Find the top of the box
and open it. Holding the flaps open, roll the box over until it is upside-down. Lift the box off.
Lift the subwoofer off the foam corners and place it on the carpet/blanket. Remove the protective bag and
inspect for damage. If all looks fine, turn the subwoofer so the bottom faces up (the face with the four screw
holes). Screw in the feet. If the subwoofer has a protective stick-on plastic, leave it on until you decided to
keep the subwoofer for good. Any returned product with scratches, etc. will be subject to a restocking fee.
Upright the subwoofer and move it to the desired location.
Step 2: Placement
Contrary to popular belief, placement is extremely important. It can dramatically affect the bass
quality and quantity. An optimally placed subwoofer is much more powerful and better sounding
than a poorly placed one.
Important Guidelines
• This subwoofer does
not
have magnetic shielding and has a HUGE magnet (35 lbs!). Keep the sub-
woofer at least 5 ft away from CRT TVs or video displays. LCD, plasma, and DLP TVs are not
affected, and the subwoofer can be placed next to these items with no magnetic interference. Keep
the subwoofer at least 2 ft away from computers in order to prevent the hard drive from being erased.
Rules of thumb for placement
•
Avoid the center of the room:
In general, avoid placing the subwoofer half way between the front
and back walls. You should avoid sitting in the middle as well.
•
Use near-field placement:
You get the tightest upper bass and the most punch if you can place the
subwoofer close to you. By being close to the subwoofer, you get high SPL without requiring a lot
of power. This helps to minimize annoyance to your neighbors as well. The direct- to- reflected ratio
is also higher, helping to reduce room effects. One situation where near-field placement may not work
best is when your room is very shallow. In a shallow room (less than 15 ft front to back), placing the
sub close to you will lead to a dip in the low bass response.
•
Corner placement:
If near-field placement is not optimal, then corner placement is a great alternative.
A front corner furthest from openings is generally optimal for deep bass reproduction.
•
Placement in entertainment centers:
This is acceptable as long as you can fire the woofer straight
into the room, and you have at least 1˝ spacing on the sides, top and back (measured from the heat
sink). The air in the cavity must be able to circulate with the outside air to get proper cooling. Make
sure the entertainment center will not vibrate and rattle. Use the rubber feet if placing the subwoofer
in an entertainment center.
•
Direct line of sight between subwoofer and wireless transmitter:
If you are using the wireless
connection, the signal is most reliable if there is nothing blocking the subwoofer from the wireless
transmitter. Also, the transmitter should not be too close to the ground, preferably 18˝ or higher. Do not
worry too much if these criteria cannot be met. We have tested thise subwoofer with the transmitter on
the ground, and in a room with four walls between the transmitter and the subwoofer, and the wireless
technology still works fine.
