SR3 presents a clean and simple dipolar design that is sure to impress. No expense was spared when engineering the dual 4- inch bass drivers. Both drivers are carefully tuned to create a frequency response that goes down as low as 70Hz. More importantly, the SR3 is able to reproduce an exceptional surround sound field with extraordinarily wide staging. The SR3 effectively eliminates the localization problem found in other surrounds. Starke Sound’s SR3 carries the same tweeters, midrange, and bass drivers that are found in the H3 Elite Series.
