Overview

Your Sunfire SubRosa subwoofer is designed to give you the best possible low-frequency sound quality for your Home Theater experience. It incorporates a tremendously powerful amplifier and a pair of drivers to produce tight, floor-rum- bling, denture-rattling bass that you can feel as well as hear.

The subwoofer has an automatic equalization system that will tailor the subwoofer output to compensate for any room effects. It also has a manual equal- ization mode.

The subwoofer has an adjustable high cut filter and line-level inputs for easy incorporation into existing systems, or as part of a subwoofer/satellite speaker combination.

Controls for adjusting the volume, crossover frequency and phase, allow the subwoofer to be perfectly matched to any listening environment and audio components.

The Drivers

To have lots of bass requires moving lots of air. Your Sunfire subwoofer incor- porates two drivers that can move back and forth approximately five times more than a normal subwoofer. This gives it a lot of air moving capacity which allows for majestic bass performance.

The woofers are high-strength designs, using neodymium magnets.

The Amplifier

The large movement range of the driv- ers creates greater air pressure inside the box than a conventional subwoofer. Therefore, the drive amplifier must be much more powerful than an ordinary subwoofer amplifier. In fact, it has to be so powerful, it is almost hard to believe.

The power amplifier within your Sunfire subwoofer is capable of delivering over 2,700 watts. When the same full output is applied to the drivers, however, the enor- mous back-electromotive force generated as a consequence of its large motion and giant magnets, causes the current flow to be much less. It is this singular property of the drivers that allows the subwoofer to be approximately ten times more ef- ficient than a subwoofer this size would normally be.

A compressor circuit kicks in automati- cally if the input signal level reaches a level that would overload the drivers. 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 subwoofer to put more sound into the room to satiate the power hungry user, but without distortion or damage to the subwoofer. Thus, for ex- plosive scenes in movies, this produces extremely high sound pressure levels (SPL) in your room without the drivers banging against the mechanical stops.
