QSC KLA181 18” Active Flying Subwoofer
The KLA Series brings the power and sophistication of a line array system into an easy-to-use product significantly redefining the line array product category.

With its simple Lift, Click and Play approach, KLA can be deployed in a fraction of the time required by comparable line array products.
This fixed or “arcuate”, active line array system is ideal for a wide range of portable and permanently installed applications ranging from live entertainment to houses of worship or other venues where a line array system is desired.

- Frequency range down to 33 Hz (-10 dB)
- Extensive DSP further enhances and protects performance
-
powerCON® Input and Thru connections

- Suspension made possible via M10 fittings or KLA12AF Array Frame
- Integrated threaded pole mount supports up to two KLA12 enclosures (black models only)
The KLA Series is comprised of two models, the KLA12 12-inch, 2-way loudspeaker and the KLA181 18-inch subwoofer.
The KLA12 features a highly efficient 500 watt by 500 watt power amp module and the KLA181 offers the same highly efficient power amp module in a 1,000 watt configuration.
This efficient design enables up to five KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15 amp, 120 volt electrical circuit.
KLA loudspeakers incorporate QSC’s DEEP™ DSP algorithm – providing extended bass response by actively managing potentially damaging low-frequency transients – and GuardRail™ circuitry protection which prevents the amplifier module from unnatural and destructive clipping.
As an energy saving feature, the Auto Standby mode automatically engages after five minutes of inactivity but upon resumption of audio signal, the power module on the KLA will awaken instantly for immediate output.
In an installed application, multiple KLA Series loudspeakers can be “daisy-chained” for total gain control from a single remote pot wired to the on-board Phoenix-style connector.
Additional power module characteristics on KLA include a balanced, line-level XLR input in parallel with an XLR “Thru” connector, PowerCon™ In and Thru connectors, Attenuation Control and LED indicators for Signal, Limit, Power and Standby status.
In addition to DEEP™ DSP algorithm, GuardRail™, Auto Standby, balanced line-level XLR input with an XLR “Thru” connector, Attenuation Control and LED indicators, the KLA181 subwoofer also includes a polarity switch to optimize summation between subwoofer and top-boxes.
Two KLA12 Loudspeakers over the KLA181 Subwoofer
For maximum deployment flexibility, KLA loudspeakers can be either ground deployed or flown.
As a ground stack, up to two KLA12 enclosures can be mounted over the KLA181 or the KW181 subwoofer via a threaded pole socket, or without a sub using an appropriately rated loudspeaker stand.
Arrays of up to 480 lbs (218 kg) (with a maximum five KLA12 and two KLA181 enclosures) can be flown via the included M10 fittings or the optional KLA AF12 array frame.
