Bose Professional Bose Sub1/Sub2 Adjustable Speaker Pole

The Sub1 and Sub2 powered bass modules each carry an M20-threaded pole mount on one side, and this is the pole Bose builds for it. Lay the bass module on its side, thread the pole in, and the top box sits above head height instead of on the floor, which is the difference between a room hearing the vocal and the first two rows absorbing it. It carries an S1 Pro, an L1 Pro8 or L1 Pro16 array, or any cabinet with a standard M20 socket.

Construction is stainless steel with a standard male M20 thread, and the telescoping section runs out to 132 cm (52 inches) with a locking pin that holds the set height rather than relying on friction. That matters on a stage that gets bumped. The pole packs down short enough to travel with the sub, so a two-piece portable rig stays a two-trip load-in.
