Add epic low end to your live rig, with a KLA181 subwoofer from QSC. This hard-hitting 1,000-watt active subwoofer features QSC's amazing DEEP DSP algorithm, which smoothly shapes bass frequencies for maximum impact. GuardRail protection allows the KLA181 to deliver maximum peak power, without overloading. That lets you keep the crowd amped up, without risking show-stopping shutdowns. The KLA181 sub also features both a balanced line-level XLR though jack and a locking AC power through jack - perfect for daisy chaining up to a set of KLA12 top boxes pole-mounted overhead.
