Subwoofer Installation

Your new ForceField subwoofer contains a built-in amplifi er and electronic crossover. Of the several ways to install your subwoofer, none is considered “better” than another; rather, each is best depending on what type of entertainment system you own and how you plan to integrate your subwoofer. Read these installation suggestions below to determine which options best suit your needs. Please take care to perform all wiring procedures with your system completely off.
Power Requirements
The ‘Watts’ (W) rating indicated on the rear panel of your GoldenEar Technology ForceField subwoofer is the maximum a/c power the subwoofer will draw when producing its maximum power output. However, the actual wattage draw will vary with the bass content of the program material and is typically MUCH less (below 100 watts in normal audio playback use).
Subwoofer Placement
Bass is less and less directional as it goes down in frequency, so your subwoofer can be located almost anywhere in your listening room. (Your GoldenEar Technology subwoofer has been designed to operate at frequencies generally below 150 Hz.) For best sonic integration, locating your subwoofer between your front speakers or beside one of them and close to the front wall will usually provide the best bass performance. If this location is not possible your subwoofer may be placed anywhere in the room without affecting the image and soundstage of your stereo or multichannel speaker system. (See additional notes below about installing your subwoofer in a cabinet.)
Here are some principles to keep in mind when deciding on your subwoofer’s placement:

1. For maximum output, the subwoofer should be placed close to a wall. Corner placement will increase the subwoofer’s output, but may exaggerate room nodes (peaks in frequency) causing muddy, ill-defi ned bass performance in the room.
2. While one GoldenEar Technology subwoofer will always sound great, the use of two subwoofers will definitely enhance your system’s performance by providing a smoother and more consistent room response. With two subs, it is recommended that you locate the subwoofers out of the corners on the same side of the room as the main speaker of the same channel -or- one in the front of the room and one in the rear of the listening room.
3. Always remember that frequency response and output level are greatly influenced by the subwoofer’s placement. A movement of even a foot or two can dramatically change your room’s bass response characteristics. We recommend you experiment with placement in your particular listening room in order to achieve the highest performance from your ForceField subwoofer.
4. This figure highlights how the bass output is generally affected by room placement. When seated in a typical listening area of your room, placing the subwoofer inside the “shaded” areas will typically result in the best bass performance. Corner placement provides the most bass, but at the expense of accuracy.
   A subwoofer placed near a wall usually provides a good balance of quantity and accuracy.
   Controls on the back panel of your subwoofer are provided to align your subwoofer’s output to the other speakers in your system, see the section below on “Fine Tuning.”

Placement Inside a Cabinet Or Cavity
The ForceField subs, because of their unique low-frequency radiation properties, can be placed inside a cabinet or cavity and still provide excellent in-room performance. Just be sure to leave at least 2 inches of clearance on the front of the subwoofer.
The Advantage of Using Two Subwoofers
Although a single GoldenEar Technology ForceField subwoofer provides exceptional performance and substantial output, the quality and quantity of bass can be further improved with the use of two (or even four) subwoofers. This allows you to randomize the standing waves within your listening room so that bass will be distributed in a more uniform manner. Two (or more) subwoofers also provide even lower distortion, especially at high output levels.
The extra care you take in correctly positioning the subwoofer will result in greater listening enjoyment. So, keep the following guidelines in mind when deciding on the best subwoofer placement:
Placing Two Subwoofers in Your Listening Room
GoldenEar’s ForceField subwoofers are engineered to be used singly or in stereo pairs. With a single subwoofer, both left and right signals are combined (either at the subwoofer or at the receiver/processor). With stereo subwoofers, the left and right low-frequency signals can be reproduced by their own individual subwoofers. The use of one subwoofer achieves outstanding performance; however, the addition of a second subwoofer (one for the left and one for the right channel) clearly offers the highest level of performance achievable for both movies and music. Two subwoofers also couple much better to the air in your room (four times better) and of course offer double the power.
In addition to the above-mentioned setup for stereo subwoofers, some state-of- the-art home theater installations have begun to use a separate subwoofer placed in the rear of the room and we recommend this for the absolute ultimate in-movie bass performance. When using two subwoofers, placing one in the front of the room and the other in the rear of the room usually provides the best bass performance and sonic integration. If those locations are not possible or if you want to experiment with placement options using two subwoofers, the following procedure will be a helpful guide to achieving better bass performance. Refer to “Subwoofer Connection” and then proceed as follows:

1. Temporarily turn all speakers off (either by turning your amplifi er off or disconnecting them);
2. Connect and place one subwoofer in the central area of your listening room (follow directions for connection, as outlined in the following section);
3. At a moderately loud level, play music or a video soundtrack with extended bass that is repetitive or continuous;
4. Walk around your room and note where the bass sounds louder and where it sounds quieter;
5. Place the first subwoofer within a louder bass area of your room; then place the second subwoofer within a quieter bass area of your room;
6. Connect both subwoofers and switch all speakers back on; and switch the amplifi er on, or reconnect it;
7. Now follow the “Fine Tuning” instructions after the Subwoofer Connection section to optimize your system’s overall bass performance.

NOTE: The preceding is only a guideline. You may want to use a bass test disc and SPL meter to more accurately determine the bass characteristics of your listening room (see dealer for more information). Remember that room acoustics vary, so it may take some experimenting with placement to achieve the best performance.

Subwoofer Connection

SAFETY PRECAUTION: Before proceeding with this section be sure to read and follow all safety precaution and instruction notices at the beginning of this manual.
Turn all components OFF before connecting the subwoofer.
IMPORTANT: To achieve all the superb bass performance that your ForceField subwoofer is equipped to offer, it is important that you become familiar with its comprehensive Input/Output and Control Facilities. Before connecting your subwoofer, read the following sections carefully.
We recommend the use of high-quality cables and connectors when hooking up your subwoofer (see your dealer).
INPUT/OUTPUT FACILITIES
Line-Level (RCA) Input – Allows connection from the Sub/LFE Output of an A/V receiver, processor, or other suitable low-passed, low-level source. PLEASE NOTE: The low pass crossover control does not function when using this direct-coupled input.
High-Level Input/Output – Allows connection from the Left/Right Main Speaker Terminals of your receiver or amplifi er. Speaker-Level Output sends a high-passed signal to the Left/Right Main speakers.
CONTROL FACILITIES
Your GoldenEar Technology ForceField subwoofer is equipped with operating controls on the back panel to ensure excellent flexibility and maximum performance in any installation. Most of them are the “set and forget” type, although you may occasionally find certain controls require minor adjustments.
Subwoofer Level – This is volume control, use it to balance the subwoofer output level to best blend with your other speakers. For suggestions on setting the Subwoofer Controls once your subwoofer has been connected refer to the section on “Fine Tuning” below.
Crossover Control – Controls the subwoofer’s upper-frequency cut-off. This control (low-pass filter) is continuously variable between 40 and 150 Hz. This low pass filter control is used to obtain the optimum transition between the subwoofer and your main speakers when the subwoofer is connected using the Speaker-Level Inputs. We receive many questions from subwoofer owners asking us where to set the filter controls in a variety of different setups. Although many people think that there is a specifi c frequency at which to set the controls in their system, this can only be determined by you. Experimentation is recommended (due to system placement and subjective variables) to obtain the best sound for you. See the “Fine Tuning” section below for some suggestions.
Auto-On/Standby or Always-On – Your subwoofer will turn on when it receives an input signal — eliminating the need for a power switch. If no signal is sensed for a period of time, the subwoofer will automatically switch off. See the “Powering Up the Subwoofer” section below for more details.
High Pass Filter – Your subwoofer is equipped with a Speaker-Level high pass filter set at approximately 150 Hz (depending on the impedance of the connected speaker) which is used when you wire the Speaker-level inputs of your subwoofer and the Speaker-Level Outputs to your main Left and Right speakers.

Connection Options
Before connecting your subwoofer, please read this section to determine which setup option best suits your needs. (See your dealer if you require additional information or assistance.)
Line-Level Input From Sub/LFE Output – For use with a receiver, processor, or subwoofer control unit that has a Sub-Out/LFE-Out jack – Using an RCA-to-RCA interconnect cable connect the subwoofer as shown. Most a/v receivers, preamps, and processors feature a mono (line level) Sub/LFE output intended to be used with subwoofers. You can feed this Sub/LFE output of you’re a/v receiver or processor to the Sub/LFE input on the subwoofer and achieve full performance. These outputs have their own low-pass filter built into the circuit as part of their bass management setup. The Sub/LFE inputs on your ForceField subwoofer are direct coupled inputs that are not affected by the subwoofer’s crossover control (low-pass filter).
If the sub output on your receiver is full range (does not have a lowpass crossover – or you wish to use the ForceField subwoofer’s lowpass crossover), then you must hook up using the Speaker-Level Inputs and Outputs.

High-Level (Speaker Wire) Input From L/R Main Speaker terminals of Receiver or Amplifi er – When your GoldenEar Technology ForceField subwoofer is hooked up via high-level connections, you have the option of running your main speakers “full range” or rolling off the low-end by using the high-pass filter built into the subwoofer. To hook up your ForceField subwoofer via the high- level connections simply run the speaker cable from the right channel high- level input connector on the subwoofer to the right channel speaker connector of your receiver or amplifi er, repeating this process for the left channel. (See figure below). Using appropriate quality speaker wire, hook up the left main/front channel red(+) terminal of your receiver or amplifi er to the Left High-Level Input red(+) terminal of your Subwoofer and the left main/front channel black(-) terminal of your receiver or amplifi er to the Left High-Level Input black(-) terminal of your Subwoofer. Connect the right channel main/front channel red(+) terminal of your amplifi er or receiver to the right High-Level Input red(+) terminal of your Subwoofer and the black(-) terminal of the right main/front channel of your receiver or amplifi er to the right High-Level Input black(-) terminal of your Subwoofer.
Your main speakers can now be connected in one of two ways. If you wish to utilize the high-pass filter built into your subwoofer and roll off the bass to the main Left/Right speakers, simply connect your main speakers to the high- level out terminals on the subwoofer as shown: Hook up the left main/front speakers by connecting the left High-Level Output red(+) terminal of your subwoofer to the red(+) terminal of your left speaker and the left High-Level Output black(-) terminal of your subwoofer to the left speaker black(-) terminal. Connect the right High-Level Output red(+) terminal of your subwoofer to the right speaker red(+) terminal and the right High-Level Output black(-) terminal of your subwoofer to the right speaker black(-) terminal.
It is essential that all speaker wire connections speakers be connected in the same way (in phase: “+” to “+” and “-” to “-”) to their own channel of the amplifi er. This will ensure an absolute phase throughout your system. If you experience a great lack of bass, it is likely that one speaker is out of phase (+ and – reversed) with the other. This connection will provide a smoothly contoured roll-off of the low frequencies going to your main speakers, starting at about 150 Hz.
If you wish to run your main speaker’s full range with no low-frequency roll- off, hook them directly to the main speaker output terminals or your receiver or amplifi er as in any normal hi-fi system. This is recommended ONLY if your main Left/Right speakers are true full-range systems. If not, you may find that you are over-driving your main speakers. You will be able to play your system louder without overdriving your main speakers by using the built-in high-level high-pass crossover.

DUAL SUBWOOFER CONNECTIONS
Connection Using High-Level (Speaker Wire) Inputs: Instead of running both speaker cables from your receiver or amplifi er to the left and right high-level terminals on the subwoofer, you will run the left channel to the left channel subwoofer and the right channel to the right channel subwoofer. Again, take care to make red-to-red (+) and black-to-black (-) terminal connections. For further setup instructions, refer to the Fine Tuning section further below.
Connection using low-level Inputs: From your receiver or preamp, attach an RCA-type “Y” connector to the Sub/LFE out (unless your receiver or processor has two Sub outs) and then run an RCA-type interconnect cable to each subwoofer’s low-level input. In this setup, main speaker connections are made between your receiver or amplifi er in a traditional manner. For further setup instructions, refer to the Bass Management Systems Setup section below.

BASS MANAGEMENT SYSTEMS SET UP

(FOR MULTI-CHANNEL, 5.1, ETC., SYSTEMS)
Multi-channel surround sound systems have a critical speaker setup and channel balancing procedure for setting the level for all speakers and how the bass is directed which must be followed if the system is to perform properly. Many problems relating to the overall sound of the system can be clearly traced back to improper system balance. Also, note that multi-channel surround sound systems have bass management systems which vary from unit to unit. This bass management system must be properly adjusted. Many problems relating to the overall sound of the system can be traced back to improper bass management settings.
Bass Management Settings when using High-Level (Speaker-Wire) Input: On your receiver or A/V processor’s Speaker Setup Menuset Left and Right main speakers to “Large” and set the Subwoofer to “No” to direct all bass and LFE information to L/R Main Speakers – and therefore the Sub(s).
Bass Management Settings when using Low-Level (Sub/LFE) Input: On your A/V receiver or processor’s Speaker Setup Menu set all speakers to “Small” and set Subwoofer to “Yes” to direct all bass and LFE information to the Sub(s).
Setting Channel Levels: Using your receiver or A/V processor’s Speaker Level Calibration Menu, set each speaker (channel) in the system to the same volume level. While you can get reasonable results doing this by ear, it is best to use an inexpensive Sound Pressure (SPL) meter to get better channel- to-channel balance. Some new receivers and processors have Auto Set Up functions that use a supplied microphone to set levels automatically. Also note that bass level should be set to individual taste, not just to a given reading on the SPL meter. Also note that most inexpensive SPL meters suffer signifi cant roll-off when measuring bass frequencies, making it even more important to “adjust the bass to taste.”
NOTE: When using a High-Level (speaker wire) connection, the subwoofer level will be set by the subwoofer’s level control, not the bass management system of you’re a/v receiver or processor.
(*Small and Large settings on speaker setup menus determine the routing of bass information, see your dealer for more assistance on the correct settings for your specifi c speaker system and environment.)

FINE-TUNING
Once you have the rest of your speakers positioned in the room (and have set speaker distances and calibrated speaker levels with your Processor or A/V Receiver, if applicable) it’s time for a little fine tuning.
( NOTE: Set tone or equalizer controls on your receiver or preamplifi er to fl at (or 0°) and switch any loudness controls off.) When setting up your subwoofer use music and video soundtracks that you know well. They should contain selections with extended bass that is continuous and repetitive. When you are adjusting your subwoofer, remember: Bass should not be overbearing — the subwoofer should not draw attention to itself — but the overall system sound shouldn’t be “thin” or diffi cult to hear.
The following procedure is only for set ups utilizing the High-Level (Speaker wire) connections on the subwoofer, and are simply a suggested method to achieve the best results. (If using the low-level Sub/LFE input with an A/V receiver or processor to control crossover settings and levels, skip this section):

1. Turn the Subwoofer Level control completely counter-clockwise to its minimum;
2. Turn the Subwoofer Cut-Off Frequency control to its highest frequency (i.e. 150 Hz);
3. While you listen to a music or movie selection in your primary listening area, have an assistant turn up the Subwoofer Level control until the subwoofer can be clearly heard;
4. Turn the Subwoofer Level control completely counter-clockwise to its minimum;
5. Turn the Subwoofer Cut-Off Frequency control completely counterclockwise(i.e. 40 Hz);
6. Slowly rotate the Subwoofer Level control until you match the subwoofer output level with the level of your front speakers. Bass should be clearly audible, but not intrusive;
7. Slowly rotate the Subwoofer Cut-Off Frequency control until you hear the best subwoofer/main speaker blend. If the sound is too “thin,” you have not set the frequency high enough; if the sound becomes “boomy” you have set the frequency too high. Adjust until you fi nd the most natural balance.

Complete Home Theater Systems

We strongly suggest that you use a matching GoldenEar Technology Left, Right, and Center channel, and Rear/Surround speakers to complete your GoldenEar home theater system.
Powering Up the Subwoofer
Your ForceField subwoofer contains a built-in, active-powered subwoofer section as well as an electronic crossover. Each ForceField subwoofer must be plugged into an electrical socket (use an unswitched outlet if possible) of the appropriate voltage (as indicated on the back of your unit) using the plug on the end of the black cord attached to the electronics module on the back of the subwoofer. The ForceField subwoofer has a special circuit that automatically turns the powered subwoofer section on when a signal is fed to the loudspeaker and does not require an on/off switch. (When the Subwoofer is first plugged in, the LED will fl ash for 30 seconds while the sub conducts a self-test, initializing the software and hardware. After 30 sec, if there is no audio signal, the LED will turn off and the subwoofer will go into standby mode drawing a low amount of power while waiting for an audio signal.)
The LED on the back panel will light up when a signal is sensed and the amplifi er will turn on. After you stop listening, it may take up to an hour for the amplifi er to actually turn off. (Please note: In some instances, because of RF presence in your area, the LEDs may not turn off. However, this is nothing to be concerned about as the amplifiers draw almost no power when they are idling.) Please note: It is normal to hear a slight pop from the subwoofer when the amp powers up.
NOTE: To prevent accidental damage to your subwoofer from overdriving the system, the subwoofer features an internal overload protection circuit, which will turn the subwoofer off or down when overdriven or overheated and will then resume normal operation after a few minutes.

Troubleshooting

If you experience any difficulties with your ForceField speakers, try the suggestions described below. If you are still having problems, please consult your GoldenEar Technology Authorized Dealer for assistance.

1. Make sure all your system interconnects and power cords are solidly in place.
2. Should you experience any level of ground hum or noise, try plugging the power cord into the same circuit as your amplifi er.
3. The system is provided with sophisticated internal protection circuitry. If for some reason the protection circuitry is tripped, please turn down your system’s volume and wait fi ve minutes before trying the system again. If the amplifi er should overheat, the system will turn off until the amplifi er cools down and resets.
4. Check to be sure that your power cord has not been damaged.
5. Check that no foreign objects or liquid has entered the subwoofer.
6. Check the fuse on the back panel (replace only with the exact matching value fuse)
7. If you cannot get the subwoofer to turn on or if no sound comes out and you are sure the system is set up properly, please bring the Subwoofer to your GoldenEar Technology Authorized Dealer for assistance. But make sure you Call First.
