Overview
The SPM300 is a threaded speaker-mount pole designed to mount a powered speaker on top of a compatible subwoofer (especially matched with DLM-series subwoofers), enabling a compact, full-range PA system with minimal footprint.
It allows you to stack a top speaker over a subwoofer, turning separate boxes into a unified PA rig — ideal for mobile setups, rentals, small venues, or events where space and portability matter.
