2-Pack 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 2-pack includes two 40.5-inch heavy-duty steel speaker poles. 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.

Key Features

🔊 38MM SPEAKER MOUNT - The opposite end features a 38mm / 1-1/2" pole for compatible full-range speaker cabinets.

🔄 38MM-TO-35MM ADAPTER INCLUDED - Use the included adapter to convert the 38mm upper pole to 35mm / 1-3/8" for compatible speakers with standard 35mm pole sockets.

📏 FIXED 40.5" HEIGHT - Positions compatible full-range speakers approximately 40.5 inches above the subwoofer for a clean, space-saving PA configuration.

💪 80 LB MANUFACTURER-STATED CAPACITY PER POLE - Each SS40 is rated to support up to 80 lb when properly installed with compatible speakers and subwoofers.

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.

• The original package section listed only one pole despite the title stating 2 Pack. This listing follows the 2-pack title and lists two poles and two adapters.

Important Safety Note

• The 80 lb capacity is a manufacturer-stated rating per pole and should not be interpreted as a 160 lb complete-system rating.

• 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.
