Overview

The Sunfire HRS subwoofers are 

designed to give you the best possible 

low-frequency sound quality for your 

Home Theater and music playback expe-

rience. They incorporate a tremendously 

powerful built-in amplifier to produce 

tight, seismic, denture-rumbling bass that 

you can feel as well as hear.

There are three models in the high 

resolution series: the HRS-8, HRS-10, 

and the HRS-1. (The number represents 

the driver diameter in inches.) The control 

panel, connections and operation are the 

same for each subwoofer model, and this 

manual covers all three models.

Each subwoofer has controls for adjust-

ing the crossover frequency, phase, and 

volume. They also have line-level and 

speaker-level inputs for easy incorpor-

ation into existing systems, or as part of a 

subwoofer/satellite speaker combination.

The Driver

To have lots of bass requires the move-

ment of lots of air. To achieve this, the 

subwoofer's driver has been designed to 

travel back and forth approximately five 

times further than a normal driver. This 

gives lots of air movement and massive 

bass performance. 

The Tracking Downconverter 

Amplifier

The large movement range of the driver 

generates greater air pressure inside the 

box than a conventional driver. In order 

to create this range of movement, we 

designed a drive amplifier that is much 

more powerful than an ordinary amplifier. 

A signal compressor circuit kicks in 

automatically if the input signal level 

reaches a level that would overload the 

driver. This maintains a ceiling on the 

output without clipping.

If the input signal is driven even further, 

a ‘soft clipping’ circuit is enabled. This 

allows the driver to put more sound into 

the room to satiate the power hungry 

user, but without distortion or damage to 

the driver. This produces extremely high 

sound pressure levels (SPL) in your room 

without the driver banging against its 

mechanical stops.

Sub/LFE

In this manual, the term “Sub/LFE” is 

used to denote the subwoofer or Low 

Frequency Effects output, commonly 

found on Home Theater processors and 

receivers.
