introduction
This manual covers operation information for the Cerwin-Vega’s XLS-12S & XLS-15S Subwoofers. Illustrations of control locations and
hook-up wiring may differ in physical appearance and location than those shown on the actual product you own. However, the operation
information is still the same.

subWoofer installation
prior to installation
2.1
Carefully unpack your subwoofer and save the box and all of the packing material. At some point, you may need to transport, ship, or move
your subwoofer. Before continuing with the installation, please make sure the subwoofer is unplugged and the power switch is turned “OFF.”
warning: Severe damage may result from improperly selected voltage. Refer to qualified service personnel to select voltage.
2.2
installation
Please read the following to determine which installation procedure is best for your audio/video system. For additional hook-up connections,
you may want to refer to your A/V receiver, processor, preamplifier, or amplifier’s manual.
note: Read carefully the “Important Symbols and Safety Instructions” page before starting the installation.
2.3
ControL desCriptions
The following controls are located on the XLS subwoofer’s rear panel (Figure 1), page 2.
attention! The Cerwin-Vega’s XLS Subwoofers have LFE, Line Level, and SPEAKER-LEVEL input connections. Please choose one option
only for hook-up. Do not hook up more than one option!
1. Lfe input: Mono “low frequency effects” connection. Use this input if receiver/preamp/processor has a dedicated LFE or subwoofer
OUT. Refer to the owner’s manual provided by your receiver/preamp/processor manufacturer. Set receiver’s crossover to 150 Hz.
2. Line LeVeL input: Stereo low-level input to subwoofer. Connect to “LINE-OUT”, “MAIN-OUT or PREAMP-OUT,” of your receiver/
preamp/processor using a dual RCA patchcord (not supplied). Refer to the owner’s manual provided by your receiver/preamp/processor
manufacturer. Set receiver’s crossover to 150 Hz.
3. speaKer LeVeL input: Stereo high-level inputs to subwoofer. Use these terminals when line level connections are not available from
A/V receiver/preamp/processor. Connect to SPEAKER outputs on receiver using high-quality speaker wire (16-gauge or heavier). Set the
front left and right speaker settings to large or full range.
4. speaKer LeVeL output: Audio loop of stereo high-level (SPEAKER LEVEL) inputs. Use to loop (continue) signal to speaker
connections to the left and right main speakers.
5. VoLume ControL: Controls volume level of subwoofer. Use to balance the output of the subwoofer with the main speaker output.
6. CrossoVer freQuenCy: The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 50 to
150 Hz. The subwoofer’s response will begin rolling off above the set frequency.
note: Crossover control does not function when LFE input is used.

2.3 ControL desCriptions (Cont.)
Figure 1
7. pHase: This switch allows you to compensate for having the subwoofer in a different location than the main speakers. This control allows
the signal to be delayed 180 degrees so the output of the subwoofer will blend in with the main speakers. Slide the PHASE switch to “180.”
At the listening position, listen to the mid bass output. If it sounds weak, set PHASE back to “0.”
8. power Led: Power indicator lamp. Glows green in “ON” mode if audio signal is present. Glows red in both “OFF” mode and “ON” mode
if receiving AC power, and if audio signal is not present after approximately 30 minutes.
9. power: Two-position power switch. In the “ON” mode, the subwoofer’s amplifier is automatically activated if an audio signal is present
and will automatically become inactive when there is no audio signal present after approximately 30 minutes. In the “OFF” mode, power is
shut off to the amplifier.
10. VoLtage seLeCtion: XLS products have 120 V and 240 V capabilities and are shipped with voltage specific fuses:
(110 V – 120 V – T6.3AL / 220 V – 240 V – T3.15ALAC).
warning: Severe damage may result from improperly selected voltage. Refer to qualified service personnel to select voltage.
11. power Cord reCeptaCLe: Connect the IEC cord to this receptacle (supplied with the subwoofer). If the IEC cord does not fit in
your AC outlet, please purchase another AC cord from your audio dealer or electrical supply store.
12. repLaCeabLe fuse: Protects system from overload. Refer to qualified service personnel to change the fuse.
2.4
placement
Your XLS Series Powered Subwoofer produces low frequencies which are omnidirectional. As a result, placement requirements for your
subwoofer are flexible and subject to your listening room’s acoustic characteristics. To determine the best position for your subwoofer, start
by positioning it along the same wall, or plane, as your main speakers. Experiment with various locations until you find the location that
sounds best to you.
note: Typically, your powered subwoofer will sound best when placed between the front main satellites.
Caution! Do not place heavy objects of any type, such as televisions on top of any Cerwin-Vega! speaker unless otherwise recommended
by Cerwin-Vega! XLS Series speakers are for residential applications only.
* Refer to the owner’s manual provided by your main speaker manufacturer to determine your main speaker’s low-end frequency response.

ConneCting your subwoofer
3.1
line level connections
Connect the LFE Output of an A/V receiver to the LFE Input (1) of the XLS subwoofer, or connect the left and right line level outputs of an AV
receiver to the left and right Line Level Inputs (2) of the XLS subwoofer. (Figure 2). See your A/V receiver’s bass management instructions
for proper integration into your system.
Figure 2
3.2
speaKer level connections
Connect the left and right speaker-level outputs of an A/V receiver to the Left and Right Speaker-Level Inputs (3) of the XLS subwoofer.
Then connect the Left and Right Speaker Level Outputs (4) of the XLS subwoofer to the left and right speakers on your system. Remember
to maintain left to left, right to right, (+) to (+) and (-) to (-) connections. (Figure 3).
Figure 3
note: The signal coming from Speaker Level Inputs (3) through the Speaker Level Outputs (4) is high-pass filtered at 100 Hz*. This removes
the bass below 100 Hz from your left and right speakers. The subwoofer is used to reproduce the frequencies below 100 Hz*.
*The passive high pass filter used in the speaker level output is dependent on your speaker impedance for the actual crossover frequency.
Because of this, we recommend that you start with a crossover frequency (6) setting of 100 Hz, and then adjust Volume (5) and Phase
(7). If there is too little midbass, turn the crossover frequency up (6). If there is too much midbass, turn the crossover frequency down (6).
Experimentation and listening are the keys to proper subwoofer integration.
