Cautions
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
The back plate can become hot to the touch. Do not block or cover the fan or the exhaust louvers from ventila-
tion. There must be a minimum of 12” of space behind the fan. Do not allow the airflow to be become blocked
by objects such as curtains or drapes, thermal building insulation, etc. It is recommended that the rear of the
PVs 18 Sub not be placed in a closed space or a space that has no fresh, cool airflow.
DO NOT connect the inputs of the PVs 18 Sub to the output of a power amplifier. The inputs are meant to be
driven from a line-level strength signal.
DO NOT remove the protective metal grilles.
WARNING! The PVs 18 Sub is very efficient and powerful! This sound system can permanently damage hearing!
Use extreme care setting the overall maximum loudness!
The apparent sound level of the PVs 18 Sub can be deceiving due to its clear, clean sound output and lack of high
frequencies. The lack of distortion or obvious distress can make the sound level seem much lower than it actually
is. This system is capable of SPL in excess of 127 dB at 1 M from the speaker!
Placing A Satellite Speaker System On Top Of The PVs 18 Sub
The PVs 18 Sub has a threaded pole mount built-in to the top of the unit, and this is designed to mate with an
M20 threaded pole of approx. 32” in length or less. This pole is designed to be used with speaker systems less
than 33” high and less than 60 lbs. in weight.
Do not place a taller/larger or heavier speaker system than this on the pole, or it may be unsafe due to the poten-
tial to tip over.
The PVs 18 Sub must be placed on firm and level ground, in order for the pole mounted speaker to be safe from
tipping.
When installing or de-installing the speaker on the pole, it is a good practice to have a helper if possible, it can
be hard to “thread the needle” and mate the pole cup to the Subwoofer pole while holding the speaker system at
arm’s length.
When using the PVs 18 Sub and pole outdoors, never attach banners or flags to the pole or the pole mounted
speaker system, strong winds may cause the speaker to blow over. If there is a possibility of strong windy condi-
tions, then it may be prudent to consider removing the speaker from the pole to prevent the PVs 18 Sub and pole
mounted speaker system from being blown over.
