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 SB-2180 features two 18” (457 mm) woofers with 4” (102 mm) voice coils for extended bandwidth low frequency reproduction. With an enclosure depth of less than 17 inches (452 mm), the SB-2180 is one of the narrowest dual-driver subwoofers available, which dramatically reduces space requirements behind the screen. A unique folded port design allows the enclosure to be extremely narrow, while maintaining full port length and volume.
