Using the line-level high-pass outputs

If you are using a receiver or processor which does not have a Sub/LFE output, you can send its left and right front output into the subwoofer’s Line-Level inputs and then connect the subwoofer’s High-Pass outputs to the inputs of your amplifier.

The subwoofer will play the low frequencies, and your amplifier and front speakers will play the frequency range above the subwoofer’s fixed

(70 Hz) high-pass crossover point.

This is an excellent method if your speakers are small satellites or mini- monitors, and/or your power amplifier is of limited power, such as a tube amp.

TO FRONT SPEAKERS

For the ultimate in computer sound systems, connect the left and right audio output from your computer sound card into the subwoofer inputs. Connect the sub's high-pass outputs to the inputs of your powered speakers. You may need some RCA-to-mini plug adaptors to make the connections. Adjust the sub's volume control to match low-powered speakers. See the note about magnetic fields on page 10.

The HRS-12 is the flagship model, featuring a 12-inch driver and a powerful 2000-watt peak amplifier. It utilizes Sunfire's patented High Pressure Drive technology, which allows for a remarkable output-to-size ratio. This means that despite its compact design, the HRS-12 can reproduce deep, driving bass that fills any room. The subwoofer also incorporates a unique dual opposing driver configuration, which minimizes distortion and enhances sound clarity by canceling out unwanted vibrations.

Next in the lineup, the HRS-10 features a slightly smaller 10-inch driver, but it still maintains impressive performance. 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.

In summary, the Sunfire HRS-12, HRS-10, and HRS-8 subwoofers exemplify the brand’s commitment to delivering powerful, high-quality bass in a variety of formats to suit different needs.
