The UK's leading Integrator and Equipment
Installer for the Digital Cinema Industry


AD-S6 logo

Founded over four decades ago, QSC Audio Products, LLC, is a globally recognized leader in the design and manufacture of professional audio system solutions. Sound Associates have been specifying and installing QSC amplifiers for use in cinemas large and small for many years and now with Q-Sys we continue to deliver high quality cinema sound.

QSC introduced a full range of cinema speakers and Sound Associates is proud to have carried out all of the UK installations of their stage, sub-bass and surround speakers. The range now includes digital signal processing (DSP) and, again, Sound Associates have carried out numerous installations, both here in the UK as well as overseas.

In 2016 QCS acquired Ultra-Stereo Labs, Inc. (USL) allowing them to offer an industry-leading porfolio of sound processing solutions for the motion picture exhibition industry.


The QSC AcousticDesign™ AD-S6 is a surface mounted 16 ohm, 6.5-inch two-way loudspeaker system, ideally suited for a wide variety of foreground and background sound reinforcement applications.

AcousticDesign™ series offers integrators a premium quality installed sound solution where performance, coverage, and aesthetics are paramount. Combined with unprecedented ease-of-installation and high weather resistance, the AcousticDesign™Series provides integrators a versatile and confident response.

The AD-S6 features a high quality 6.5-inch weather treated paper cone woofer on a 1.5-inch voice coil. A carefully selected 1-inch silk dome tweeter with a 1-inch voice coil perfectly matches the sensitivity and performance of the woofer for outstanding full range reproduction.

Consistent and even 105° axisymmetric(conical) coverage is realized by means of DMT (Directivity Matched Transition™).This innovation matches the high frequency wavegide to the woofer coverage at the crossover point, resulting in a coherent transducer transition and improved off axis response.

The AD-S6 has a 16 ohm impedance making it ideal for distributed systems, without the need of a transformer, that require optimal sonic performance. All AcousticDesign Series surface-mount loudspeakers are housed in rugged ABS enclosures for long-term durability. Sealed input panel covers and powder coated aluminum grilles add weather resistance, exceeding IEC60529 IP-54 for dust and splash resistance.

Installers will appreciate the award winningX-Mount™ system, included with each full range AcousticDesign™ Series model. This ingenious mounting solution achieves unprecedented ease-of-installation in either horizontal, vertical, wall, or ceiling deployments. Knurled surfaces at the pivot planes ensure the load will not drift or sag over time. Articulation marks allow pre configuration of the X-Mount™ while on the ground with no special tools required. Once secure, the loudspeaker installs in seconds, allowing the installer to work safer, smarter, and faster with repeatable results.

To further enhance performance and speed of install with optimum result, advanced voicing filter sets using QSC Intrinsic Correction™ techniques are obtainable using the Q-SYSPlatform including CXD Series amplifiers for a complete QSC systems solution. Sensitive to aesthetic demand, the AcousticDesign Series feature a stylish appearance free of obtrusive logo adornments.

Complimenting adjacent product families, AcousticDesign surface loudspeakers are available in QSC standard black (RAL 9011) or white (RAL 9010) and may be painted to match any decor.
