Placement
Subwoofers operate at extremely low frequencies that are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. Typically, the optimum location for a subwoofer is tucked away in a corner of your listening room where the greatest output levels and optimum low frequency extension can be found. The worst location for a subwoofer is far away from any walls and close to the center of your room. Avoid these locations when possible. Depending on the room size and type of furnishings in the room, perfect placement may not be possible. Finding the best location for your environment will likely require some experimentation. We suggest you experiment with the location during setup to find what sounds best to you when seated in your typical listening position.
Caution! This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc., or near sources of excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched, or compressed in any way that could result in damaging the insulation or wire.
Regardless of where you install your VX-11 subwoofer, it must remain in an upright position (woofer facing forward). Using, shipping, or otherwise storing the subwoofer in any other position for an extended period of time may result in damage to the unit not covered by warranty.

Inputs
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, integrated receiver, line-level crossover, or receiver with pre-amp level outputs. These devices will often have a Low Frequency Effects (LFE) jack which is dedicated for subwoofer use. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of.
To alleviate this condition, we recommend the following steps:
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED
– never use just the left or just the right input. If the subwoofer’s input comes from the LFE channel of your receiver, use a “Y” splitter to divide the single input into two inputs for the Left and Right subwoofer inputs. This dual male-to-female “Y” splitter can be found at your local electronics store. If using line level connections from a preamp or signal processor, use both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer.
2) | If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to |
| the subwoofer. We recommend setting the subwoofer’s level to the 9 o’clock position |
| (the 1/4 volume setting) and then adjust the LFE channel on your receiver or processor |
| to achieve the desired bass output. See your receiver or processor’s owner’s manual for |
| more information. | | |
