Overview
The Sunfire HRS subwoofers are designed to give you the best possible
There are three models in the high resolution series: the
Each subwoofer has controls for adjust- ing the crossover frequency, phase, and volume. They also have
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.
