The company’s commitment to realistic, impactful sound reached a cultural peak in the 1970s when it co-developed "Sensurround," a low-frequency effects system used in the 1974 disaster film Earthquake to create physical vibrations in movie theaters. This expertise in powerful, low-distortion bass would become the signature trait of their consumer products for years to come. The AT-40 speakers are a prime example of that legendary design philosophy, belonging to a lineage of speakers built to rock.
