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.
proprietary 10” drivers, the C-11 produces clean, powerful and controlled bass. Three large rear-firing vents ensure ventilation of both driver and amplifier for cool running at high power.

Setting up EQ or the Room Play some familiar pieces of music that have prominent bass lines. Start with the EQ switched out and then adjust the EQ filters one by one switching the EQ in and out. It is better to start with the EQ cutting the frequencies and not boosting them. Remember that a 10 dB boost is adding ten times the power at that frequency so it would be easy to overload the system at high power levels with the EQ sliders set at maximum.
