Quality 8 200W Active Sub/Subwoofer Bass Cabinet Home Cinema Hi Fi Stereo Amp

Quality 200W Active Subwoofer Cabinet

Overview - Perfect for use at home, our stylish, compact and powerful active subwoofer will give you a quality bass note and achieve low ranges of sound that your standard speakers cannot. Simply run from your amplifier directly to the active sub, then out of the sub to your speakers.

The cabinet is made from wood and other high quality components including an 8” reinforced Driver and an internal amplifier with an active filter circuit. This will give your current speakers a surprising level of depth and warmth that they would never be able to achieve on their own.

If you require any speakers to go along with this product, please feel free to get in touch and we will suggest the right ones for you.

How to install:

1. Connect the Sub to the mains using the mains lead supplied or an equivalent, good quality fig.8 mains lead. Ensure that the mains voltage is as stated on the rear panel and the outlet has sufficient capacity to operate the sub.
   
   
2. Determine how the sub unit is to be configured. If already operating a stereo amplifier with 2 speakers, the M8S can be configured to “tap off” a signal from the amplifier output without affecting the power output of the left and right speakers.
   
   
3. Simply connecting the Left and Right amplifier outputs to the “AMPLIFIER HI LEVEL IN” terminals on the Sub and then from these terminals onto the left and right speakers effectively connects the Sub between the amplifier and speakers, which can simplify wiring, removing the need for a separate signal lead to the sub unit.
   
   
4. Alternatively, if a separate line level audio signal is available, connecting left and right RCA cables to the “LINE IN” connectors is preferred (left and right signals are fed independently to the speaker and are not electrically summed)
   
   
5. With the VOLUME control turned fully down, switch on the power on the rear panel. Once powered up, gradually turn the VOLUME up part way and play a signal through the system. Increase VOLUME as required to balance with top speakers.
   
   
6. Rotating the FREQ control will vary the cut off frequency of the internal active crossover circuit. The ideal setting depends upon the program material, types of top speakers used and personal preference. Lower settings may require higher VOLUME adjustment to compensate for the extra frequencies that are removed from the signal.
   
   
7. Take care not to drive the sub unit too hard (usually denoted by a “knocking” or “flapping” noise from the speaker cone). Sub bass is difficult to hear over full range speakers and should be almost imperceptible in operation, simply adding warmth and fullness to the sound.
   
   
8. At the lower right-hand side of the rear panel is a selector switch marked “AUTO ON – ON” Selecting AUTO ON puts the M8S into an energy saving standby mode when no signal is present and automatically switches power to the amplifier when a signal is detected. Selecting ON keeps the amplifier powered up constantly.
