QSC KC12 Wide Coverage Performance PA Speaker Bundle With KS118 Subs & Cables

QSC Says:

A high-end system built for spacious rooms and outdoor events. KC12 columns deliver wide, even coverage and pristine speech intelligibility, while dual KS118 subs add deep, impactful low-frequency extension for music and voice. Portable, elegant, and fast to deploy—ideal for corporate, hospitality, houses of worship, and live entertainment.

Where This System Excels

This system takes the technology and concept of a pair of KC12 compact column PAs and adds a pair of 18-inch KS118 subwoofers alongside for good measure. While less portable than our other QSC bundles, if its coverage and power you are looking for, this is the ultimate pairing. Whether you are a DJ looking for chest thumping sub bass or a band looking for a portable back line, this is clarity and power backed by QSC reliability. Suitable for events up to 400 in capacity, with the advantage of being configurable, allowing for the KS118 subs to be left at home and relying on the pair of KC12s for smaller functions.

QSC KC12 Active Column Loudspeaker Systems

The KC12 is a powerful yet refined column-style loudspeaker system built around 3000W of Class-D amplification. Its 2-way design combines a precision high-frequency array with an integrated low-frequency section, delivering detailed highs, articulate mids, and balanced low-end from a sleek, space-efficient enclosure.

Ideal for corporate, hospitality, and live entertainment environments, the KC12 provides consistent performance at higher levels while maintaining clarity and polish.

Wide, Even Coverage

The column architecture ensures broad horizontal dispersion and smooth vertical coverage, reducing hotspots and dead zones. This makes it especially effective for speech-focused events where intelligibility is critical, while still offering the musical detail required for DJs and live acts.

Integrated DSP allows optimisation for speech or music applications, helping you tailor the system quickly for conferences, worship services, or full-range playback.

Elegant and Efficient

With its streamlined design and fast assembly, the KC12 is well suited to venues where appearance matters as much as performance. It offers the benefits of a portable PA system without the visual bulk of traditional point-source speakers on stands.

QSC KS118 18" Active Subwoofers

The KS118 delivers serious low-frequency performance, powered by a 3600W Class-D amplifier driving a high-output 18" driver. The result is deep, authoritative bass with excellent control — ideal for live music, DJ sets, and high-impact playback.

Designed for professional touring and installed applications, the KS118 extends the system’s range with powerful sub-bass while maintaining clarity in the overall mix.

Power Meets Precision

Advanced DSP with Intrinsic Correction tuning continuously optimises performance and protects internal components. Adjustable settings allow seamless integration with the KC12 columns for a cohesive, full-range live sound PA setup.

Built for Professional Use

Durable construction and ergonomic handling make the KS118 suitable for regular transport and deployment. Despite its output capability, it remains practical for event companies and venues seeking a high-performance DJ PA bundle with extended low-frequency authority.
