This subwoofer has been designed for Home Theatre installations and to augment the bass performance of full-range speakers in 2-channel audio use. Adding the subwoofer to your system not only extends the bass to lower frequencies, it improves the midrange clarity by reducing the low-frequency demands on your existing speakers.

Please read through this manual fully before using the subwoofer. All sound installations require some planning and experimentation if you are to get the best out of the products used and this manual will guide you in this process.

As the subwoofer is connected to the electricity power supply, it is important that you familiarise yourself with the safety instructions and heed all warnings.

Keep this manual in a safe place for future reference.
