MR DJ SS40 40.5" Subwoofer Speaker Poles - M20 Threaded Base, 38mm Top with 35mm Adapter, Heavy-Duty Steel, 80 LB Capacity Per Pole

The MR DJ SS40 is a professional fixed-height subwoofer speaker pole designed to mount compatible full-range PA speakers above subwoofers equipped with an M20 threaded pole mount.

This 40.5-inch pole is made of heavy-duty steel. Each pole features an M20 threaded connection on the subwoofer end and a 38mm (1-1/2") speaker-mounting end. An included 38mm-to-35mm adapter allows use with compatible speakers featuring the more common 35mm (1-3/8") pole socket.

The SS40 is designed for mobile DJs, musicians, churches, rental companies, event production, and professional PA systems.

Important Compatibility Note

• The SS40 lower end is specified as an M20 threaded connection. This listing does not claim direct 35mm or 38mm subwoofer socket compatibility unless a separate lower-base adapter is supplied.

• The included 38mm-to-35mm adapter is intended for the speaker-mounting end, allowing a compatible 35mm speaker socket to be used with the 38mm upper pole.

• Verify the subwoofer has an M20 threaded mount before purchase.

• Verify whether the speaker uses a 38mm or 35mm pole socket before installation.

• The original supplied description refers to a "reversible upper tube," but the updated configuration describes a 38mm pole with a 38mm-to-35mm adapter. This listing follows the updated 38mm-plus-adapter configuration.

Important Safety Note

• The safe working load is limited by the lowest-rated speaker socket, pole, adapter, subwoofer mount, hardware, and supporting equipment.

• Never exceed the speaker or subwoofer manufacturer's pole-mount weight limitation.

• Position the subwoofer on a stable and level surface before mounting a speaker above it.

• Keep the speaker load centered directly above the pole.

• Do not use the pole for offset or unbalanced loads.

• Inspect the pole, M20 threads, adapter, speaker socket, and subwoofer mounting point before each use.

• Do not move or transport the subwoofer while a speaker is mounted on the pole.

• Outdoor installations require additional consideration for wind and environmental loading.
