Force XL & Titan XL Hookup

The Titan XL and Force XL subwoofers may be integrated into virtually any quality audio or audio-video system. 

First you must determine your hookup scheme. Select from the choices below and then make adjustments. (Your choice of hookup will be determined by the capabilities of the rest of your system. The Force & Titan have RCA, line-level inputs and speaker level converters are also provided for speaker level connection.)

The following diagrams and descriptions illustrate various hookup options.
Please note: For the sake of clarity, only one channel is shown.

Stereo (Two-Channel) Systems:

#1: Integrated Amp or Receiver withOUT subwoofer (or preamp) outputs.  Connection using speaker cables & speaker level converters. Also used for stereo subs.

Option #1 Using Speaker Cable & Speaker Level Adapters This is sometimes referred to as "bass augmentation". The main speakers are run full-range and the subwoofer is used to augment or fill in just the lower bass. Connect a second set of speaker cables in parallel with your existing speaker cables. This set of cables is run to our speaker level converters, which plug into the subwoofer left and right inputs. (If using stereo subs you will run one cable to each sub). Set filters A & B, the input level, and phase controls to get a seamless blend with your main speakers.

As an option, you can add a capacitor(s) in series with your main speakers. The capacitor will block some of the lows that might otherwise overdrive your main speakers. This is a very imprecise method and generally only used with small speakers with limited low frequency power handling. We recommend trying approximately 200mfd of capacitance. Polypropylene capacitors are suitable though expensive. Alternately, non-polarized electrolytic (NPE) capacitor(s) with a minimum 100 volt rating may be used.

 

#2: Integrated Amp or Receiver withOUT subwoofer (or preamp) outputs 
Same as # 1 but using shielded RCA interconnects instead of speaker cables. Also used for stereo subs. (Preferred over #1 in situations where noise or hum pickup might be a concern).

Option #2 Using Interconnect & Speaker Level Adpaters Connect speaker level converters in parallel with your main speakers. Connect a female to female RCA adapter to the speaker level converter and use shielded RCA interconnect cables to connect to the subwoofer. (If using stereo subs you will run one interconnect to each sub). (DH Labs Subsonic Cable is perfect for this application) Same capacitor option as #1.

 

#3: Integrated Amp or Receiver WITH preamp outputs and main amp inputs

Option #3 Pre-Amp Outputs & Main Amp Inputs Use Y-Adapters to split the signals from the left and right preamp outputs. Connect one end of each Y-Adapter to left or right main amp input, (using a short RCA interconnect). Use proper lengths of shielded interconnects to connect the other ends of the Y-Adapters to the right & left inputs on the sub. (If using stereo subs you will run one interconnect to each sub).

Your main speakers will receive a full range signal. To reduce low frequency content to your main amp and speakers, use optional High Pass Filters plugged into the main amp inputs.

 

#4: Separate Preamp & Amp

Option #4 Separate Amp & Pre-Amp Shown with Y-Adapters. If your preamp has two sets of outputs you will not need the Y-Adapters. Use proper lengths of shielded interconnects to connect one set of outputs to your main amplifier and one set of outputs to your sub left and right inputs. (If using stereo subs you will run one interconnect to each sub).

Your main speakers will receive a full range signal. To reduce low frequency content to your main amp and speakers, use optional High Pass Filters plugged into the main amp inputs.

 

#5: Separate Preamp & Amp, using the subwoofer's internal high-pass filters

Option #5 Using Internal High-Pass Filters We recommend this option only if highest output levels from your main speakers is the dominant criteria. We feel that the optional passive filters as in #4 are a better choice for most audiophiles.

Use shielded interconnects from your preamp output to the subwoofer left and right inputs. Then use shielded interconnects from the left and right highpass outputs to your amplifier inputs.

 

Home Theater Systems:

#6: Receiver or Processor WITH subwoofer output

Option #6 Subwoofer Output This approach requires a shielded RCA cable from the subwoofer output on your receiver or processor to one of the inputs on your Force or Titan XL.

  • Choose either the Left or Right input for the highest sound quality and the greatest bass extension. 
  • With the Left or Right input you can adjust volume at the sub and at your receiver or processor
  • Choose the Theater input only in the unlikely situation that you are able to drive your Force or Titan XL into shutdown mode. This can occasionally occur with certain content played at high levels for extended periods of time, or if the Force or Titan XL is placed such that the rear mounted amplifier is not able to cool adequately. The Theater input adds additional filtering that rolls of the low end response of the sub to allow higher sound pressure levels.
  • The Theater input bypasses the subwoofer volume controls so level will be controlled at your receiver or processor.

If you wish to use multiple subs simply split the signal with a Y-adapter and run separate interconnects to each sub. Check your receiver or processor documentation for instructions in how to turn on the subwoofer output as well as how to adjust the level.

 

Both Stereo & Home Theater Systems:

#7: Simultaneous Stereo and Home Theater Hookup
Using a subwoofer in both systems simultaneously.

Option #7 Simultaneous Stereo & Home Theater The subwoofer will accept multiple inputs. Only one source can be used at a time. Filters A & B determine the crossover frequency of the sub(s). Volume control of the theater input is controlled by your processor/preamp/receiver subwoofer level control. Volume control of the left and right inputs is controlled at the subwoofer. It is common for people to adjust their theater subwoofer level higher than they use for music only. You could also use the speaker level adapters for connection to your stereo system (see #1).
