Installation
HPR152F WARNING! Do not use a loudspeaker support pole longer than 26” (660mm) when supported by the
HPR151W or HPR181W subwoofer.
Do not rig, fly or suspend this loudspeaker product!
Before placing or installing any speaker product, inspect all hardware, suspension, cabinets, transducers,
brackets and associated equipment for damage. Any missing, corroded, deformed, or non-factory component
could significantly reduce the strength of the installation, placement or array. Any such condition severely
reduces the safety of the installation and should be immediately corrected.
Consult a licensed, Professional Engineer regarding physical equipment installation. Ensure that all local, state
and national regulations regarding the safety and operation of loudspeakers and related equipment are under-
stood and adhered to.
HPR152F: The HPR152F was designed to sit on the floor, stage, subwoofer enclosure, or be pole mounted on a
35mm diameter loudspeaker support pole. The pole can be part of a stand-alone loudspeaker stand or be inserted
into the pole cup of the HPR151W or HPR181W. Pole length must be no longer than 26” (660mm) when supported by
the HPR151W or HPR181W subwoofer.
HPR153F: The HPR153F was designed to sit on the floor, stage, or on top of the subwoofer enclosure. Do not
attempt to pole mount this loudspeaker! There is no pole cup provided.
HPR151W: The HPR151W was designed to sit on the floor or on the stage. A pole cup on the top of the enclosure
accepts 35mm loudspeaker mounting poles. Rubber feet on the enclosure’s bottom help to minimize enclosure move-
ment during operation. Do not pole mount or stack more than one enclosure on top of the HPR151W enclosure.
HPR181W: The HPR181W was designed to sit on the floor or on the stage. A pole cup on the top of the enclosure
accepts 35mm loudspeaker mounting poles. Rubber feet on the enclosure’s bottom help to minimize enclosure move-
ment during operation. Do not pole mount or stack more than one enclosure on top of the HPR181W enclosure. As
the casters will wear during normal use, it may be required to insert small foam pieces between the wheels and
frames to minimize rattling at high output levels.
Cooling
This is a self-powered loudspeaker containing an internal power amplifier that produces heat. Allow a minimum of 6”
(152mm) clearance at cabinet back for convection cooling. Keep anything that might restrict airflow away from the rear
of the enclosure (i.e draperies, fabric, etc...).
Do not use any HPR product oriented horizontally. Horizontal orientation can cause overheating and thermal lim-
iting. The cooling fins on the amplifier module must be vertically oriented in order to efficiently dissipate the heat
generated by the amplifier.
Do not install enclosures with their rear panels exposed to direct sunlight. Direct sunlight will heat the amplifier
module and reduce its ability to produce full output. Install sunshades if the application merits.
Maximum ambient temperature for full performance to specification is 40° C. (104° F.).
Do not install enclosures where exposed to rain or other water sources. The enclosure is not weatherproof. Out-
door installations must provide protection from the elements.
