The QSC Line Array speaker system consist of the incredible QSC KLA12 and QSC KLA181 that combines astounding power, amazing flexibility, and road-ready dependability in a surprisingly lightweight package that sounds absolutely amazing.
The KLA12 is powered by a 500W x 500W module that provides plenty of clean, clear power to the 12" LF driver and the 1.75" HF compression driver. Ar-Q frequency optimization lets you tune the KLA12 to the array; in fact, you can adjust for the number of speakers in your array and get the most out of your KLA12 (it allows for up to five enclosures). You'll also appreciate the SOLO rigging system, which allows you to set up the speaker without tools or hardware. If you choose pole mount the speaker, the onboard Tilt-Direct mount lets you position the KLA12 perfectly for any room.
The KLA181 is a hard-hitting 1,000-watt active sub-woofer that 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.
