The On-Stage SSA20M is a heavy-duty, steel speaker cabinet adapter designed to replace the standard 1-3/8" drop-in pole socket on top of a subwoofer. By replacing the factory socket, it updates your subwoofer to a threaded M20 connection, providing a rock-solid, wobble-free connection for compatible speaker poles and preventing top-heavy satellite speakers from leaning. 

Key Features and Specifications

M20 Threading: Eliminates the shaking and tilting commonly found in traditional drop-in 1-3/8" pole sockets.

Direct Replacement: Designed to line up with the standard four-bolt hole patterns found on most major subwoofer brands.

Heavy-Duty Construction: Made from 0.2"-thick steel with a rugged, matte black powder-coat finish.

Dimensions & Weight: Measures approximately 4.56" x 4.56" x 0.96" and weighs roughly 1 lb.

Included Hardware: Comes packaged with 4 mounting screws for quick installation.



Real-World Performance

Independent user experiences highlight the utility and installation quirks of this adapter: True Wobble Elimination.  Upgrading to the threaded M20 platform completely stabilizes top speakers and feels incredibly secure compared to loose slip-on poles.

Broad Subwoofer Compatibility: Users have successfully used this to swap out stock sockets on several popular models, including the Alto TS318s, Alto TS12S, and PreSonus Air 18s.
