Sound Barrier PM2035 — Crank-Operated Subwoofer Pole with M20 and 35mm Adapters
PM2035 Overview
The Sound Barrier PM2035 is a crank-operated subwoofer pole built for live sound reinforcement in clubs, houses of worship, and mid-size venues. Its crank-operated height adjustment allows precise speaker positioning between 33.25″ and 50″, bringing loudspeakers to ear level without manual lifting or repositioning. A soft-touch locking knob secures the desired height and guards against unintended slippage. The PM2035 is well suited for touring engineers, system integrators, and venue installers who require reliable, repeatable sub-top configurations.
The pole ships with a complete adapter kit, including two M20 cup adapters sized for both shallow and deep M20 sockets, plus a standard 35mm cup adapter, providing compatibility with the majority of subwoofers on the market.
