Information
Important Instructions
1. Read your owner's manual carefully before using the product. Retain this manual
for future reference.
2. The subwoofer should be placed at a ventilated, dry and cool location, away from
any heat sources such as radiators or amplifiers. Do not obstruct the amplifier in
the C-11 from ventilation. It is necessary that air can flow around the finned heat
sink on the rear panel of the amplifier.
3. Do not use the subwoofer near water or expose it to rain or moisture.
4. Always unplug the power cord first when making connections. Switch power on
only after you check and make sure all connections are made correctly.
5. Unplug the power cord from the outlet when you are not going to use the
subwoofer for a long period of time.
6. To clean, unplug the power cord from the outlet first. Use a damp cloth only to
wipe dust off the surface. Do not use any liquid cleaners.
7. Do not put coffee cups or other objects on top of the cabinet. They can be shaken
off when the subwoofer is in operation as it can produce a lot of vibration.

The cabinet has been designed using extensive computer modeling for the best
possible alignment between driver and box. Coupled with two high excursion
