About the SDA-SRS 3.1TL

The SDA-SRS 3.1TL is a vintage floorstanding loudspeaker from Polk Audio’s Stereo Dimensional Array (SDA) SRS line. Its SDA design uses drivers carrying information from the opposite stereo channel to reduce interaural crosstalk and broaden the stereo image; the 3.1TL is a distinct model from the larger SRS 1.2TL and 2.3TL. The TL designation identifies the version fitted with Polk’s SL3000 trilaminate-dome tweeter. The SRS line ended production in 1991.
