ProX X-SPAM20 Deluxe 20-Inch Subwoofer Speaker Pole — M20 Threaded Mount with 1-3/8″ Adapter
X-SPAM20 Overview
The ProX X-SPAM20 is a professional-grade adjustable speaker pole engineered to bridge the gap between modern M20 threaded subwoofer pole mounts and traditional 1-3/8″ satellite speaker pockets. Built entirely from all-steel construction, it supports a 125 lb. (56.7 kg) weight capacity and telescopes from 33″ to 53″ in total height, making it a reliable solution for touring companies, system integrators, and live event production. The included removable 1-3/8″ pocket adapter ensures compatibility with both legacy and current-generation subwoofer designs. This pole is suited for engineers and production crews who need a secure, wobble-free satellite speaker deployment on M20-equipped subwoofers.
Height adjustment is handled via an ergonomic Easy-Grip Tension Knob, and a captive built-in Safety Pin provides a secondary lock to prevent accidental collapse during use.
