Overview

The Mackie SPM400 M20 Threaded Speaker Pole is purpose-built for mounting Mackie loudspeakers above compatible Mackie subwoofers, creating a vertically stacked PA system that minimizes floor space. Constructed from steel with a black finish, the pole adjusts from 30 to 49 inches in height, giving sound engineers flexibility to position tops at the right elevation for consistent audience coverage. The M20 threaded twist-lock base ensures the pole seats firmly into compatible subwoofer mounts without risk of accidental rotation or loosening during a performance.

Designed with portability and quick setup in mind, the SPM400 works with the DRM18S and SR18S subwoofers on the bottom end, and accepts any Mackie loudspeaker with a standard pole socket on top. This makes it a practical addition to mobile DJ rigs, house-of-worship installs, and small-venue live sound setups where a compact, reliable mounting solution is needed without the bulk or expense of a full speaker stand.
