Installation

Observe the following general precau- tions and read the safety instructions on pages 2 and 3 before using your Subwoofer.

•Never open the cabinet or remove the metal control panel as this might result in an electrical shock to you or damage to the unit.

•Protect the subwoofer from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators.

•To prevent fire or shock, do not expose the unit to rain or moisture.

If fluid or a foreign object should enter the unit, immediately turn off the power and contact your Dealer.

•Avoid excessive exposure to extreme cold or dust.

•Do not place heavy objects on top of the unit.

•Do not place the subwoofer with its control panel against the floor.

Heat

•Allow adequate ventilation around the metal control panel of the subwoofer.

•Let nothing come into contact with the panel and keep it at least two inches away from any walls.

The metal control plate serves as the amplifier heat sink, and also removes internal heat to the outside and into the atmosphere. It can reach temperatures of 60 degrees C, which feels hot to the touch.

AC Power Considerations

Ensure that the subwoofer is plugged into an outlet capable of supplying the correct voltage specified for your model.

Unplug your subwoofer’s power cord from the electrical outlet whenever you leave the subwoofer unused for a long period of time.

Note: Never remove the ground pin from any power cords. This is very dangerous.

Route the power supply cord away from areas where it is likely to be walked on, or pinched by items placed upon

it or against it, especially near the AC wall socket, any multi power strips, or near where the IEC cord attaches to the component.

Magnetic Fields

We recommend that you place your subwoofer further than two feet away from your TV, VCR, tape deck or com- puter, so the speaker’s magnet won’t distort the colors of your TV picture or erase your video tapes, audio tapes or computer discs.

With a 1200-watt peak amplifier, the HRS-10 is capable of producing rich, deep bass that complements movie action sequences or music performances. This model also benefits from the same High Pressure Drive technology, ensuring that users experience minimal distortion, even at high volume levels.

The HRS-8, with its 8-inch driver, is designed for those who desire quality sound in a more compact form factor. Despite its smaller size, this subwoofer is powered by a 600-watt peak amplifier and delivers surprisingly deep bass. Ideal for smaller rooms or setups that need discreet audio solutions, the HRS-8 still excels in performance, making it a favorite for apartment dwellers or those with limited space.

All models in the Sunfire HRS series incorporate advanced features such as adjustable phase control, variable crossover frequencies, and a front-firing design that allows for flexible placement options. This means users can fine-tune their listening experience according to their room's acoustics and personal preferences.
