Posted by https://vipproaudio.com/ on Aug 17th 2026
If you’re looking to take your live sound from a standard PA setup to a powerful, professional line array system, the QSC KLA12 Active Line Array is built to deliver the performance, coverage and flexibility that demanding DJ, club and live sound applications require. With 1000W of total amplification, a 12-inch low-frequency driver and a 1.75-inch compression driver, the KLA12 gives you powerful low end and clear, detailed high frequencies in a compact, road-ready design.
The KLA12 is designed to make professional line array deployment easier. Its self-contained SOLO™ Rigging System allows arrays to be assembled without tools or external hardware, while the Ar-Q™ Frequency Optimization system quickly adjusts the array's frequency response according to the number of boxes being used. This makes it easier to achieve consistent sound across different venues and system configurations.
Features:
- 1000W active amplification: The KLA12 features a 500W + 500W power module, giving the system plenty of power for demanding live sound, DJ and club applications.
- Powerful 2-way design: A high-power 12-inch low-frequency driver provides extended bass response down to 44Hz, while the 1.75-inch diaphragm compression driver delivers clear and powerful high-frequency reproduction.
- Wide and controlled coverage: With a 90° × 18° nominal coverage pattern, the KLA12 can provide broad and controlled sound coverage. Just five KLA12 units can be configured to create a 90° × 90° array, making it suitable for larger sound reinforcement applications.
- SOLO™ Rigging System: Deploying a line array doesn't have to be complicated. The self-contained SOLO™ Rigging System allows you to configure the KLA12 without tools or external rigging hardware.
- Ar-Q™ Frequency Optimization: Get the array tuned quickly with Ar-Q™ technology. Simply select the appropriate number of boxes and the system adjusts the frequency response to help maintain consistent performance.
- Lightweight and rugged construction: The rugged ABS enclosure combines durability with a lightweight design, making the KLA12 practical for demanding touring, installation and live sound environments.
- Built-in DSP protection and enhancement: Extensive DSP helps optimize the speaker's performance while providing protection during demanding operation, helping the system deliver reliable sound when you need it most.
- Flexible deployment options: The KLA12 can be used as part of a larger array or as a single speaker. Its Tilt-Direct™ pole mount helps optimize directivity when using the speaker in a single-unit application.
- Professional connections: PowerCON® input and thru connections provide a practical solution for connecting power between units in professional sound system setups.
- High-capacity array configuration: With a 10:1 design factor, the system supports arrays of up to 480 lbs. (218 kg), including configurations of up to five KLA12 units and two KLA181 units.
