Its extensive product range includes active loudspeakers, subwoofers, power amplifiers, digital mixers and advanced audio, video and control systems for both portable applications and permanent installations.


QSC Audio – Professional Sound You Can Rely On
QSC Audio has been an established name in the professional audio industry since 1968. Originally focused on amplifier technology, QSC has grown into a globally recognised brand for professional loudspeakers, subwoofers, line array systems and complete audio solutions. Its combination of high-quality audio engineering, reliability and ease of use has earned QSC a strong reputation among musicians, DJs, sound engineers, event companies and professional users.
QSC stands for Quality, Service and Commitment, values that are reflected in the way its products are developed. The brand focuses on applications where a loudspeaker system must not only sound great but also deliver reliable performance under a wide range of conditions. From a compact active speaker for a small presentation to powerful PA systems for events and professional productions, QSC offers solutions for a wide variety of applications.
QSC Loudspeakers
The QSC range includes several loudspeaker families. The well-known K.2 Series, for example, has been developed as a high-quality active loudspeaker for both mobile and fixed applications. The series includes models such as the K8.2, K10.2 and K12.2. These speakers combine powerful Class-D amplification with DSP, extensive configuration options and QSC’s own technologies for controlled and consistent sound reproduction.
QSC also offers compact C Class loudspeakers, the K Class for powerful mobile applications and the modern L Class for intelligent, networkable active systems. This allows QSC to serve everything from simple mobile PA setups to larger professional systems.
Powerful Subwoofers
For applications where extra low-frequency output and high sound pressure levels are important, QSC offers a range of active subwoofers. These include compact models such as the KS112, powerful 18-inch models such as the KS118 and systems such as the KS212C cardioid subwoofer. For larger productions, the L Class also includes the LS118 and LS218.
From DJs to Professional Productions
QSC is suitable for an extremely wide range of applications, including DJs, bands, musicians, rental companies, events, corporate presentations, theatres, venues, hospitality businesses and permanent installations. QSC itself identifies event production, rental and dry hire, mobile entertainment, clubs, DJ applications, live sound and performing arts as key application areas.
For mobile users, the combination of high output power, professional sound quality and simple operation is particularly attractive. An active QSC speaker already has amplification and DSP built in, reducing the need for additional equipment and allowing you to set up a working system quickly.
For SpeakerKoning, this makes QSC an interesting choice for both beginners and professional sound engineers. Whether you’re looking for a single active 10- or 12-inch speaker, a complete system with subwoofers or a professional setup for larger productions, QSC offers a wide range of possibilities.
