The SX70 matches perfectly with the rest of the SX range both acoustically and aesthetically to bring you a home cinema experience with powerful and detailed dialogue. All the decisions we make whilst designing our products are made to make your music and movies sound amazing. The SX70 uses highly optimized woofer magnet systems to deliver controlled bass and high efficiency. We use a specifically treated paper cone to provide a smooth and even frequency response. And our silk dome tweeter delivers perfect accuracy and detail to ensure you hear every beat and every line of your music and movies exactly as they were intended.
