An adjustable steel subwoofer pole (distance rod) that mounts a PA top speaker directly above a subwoofer, raising the top box to head height so the sound carries over the crowd while the heavy sub stays on the floor.
It is tested before every rental, so it just works on the day.
A subwoofer speaker pole, also called a distance rod, is a rigid pole that turns a subwoofer into the base for a top speaker.
The lower end has an M20 threaded fitting that screws into the top plate of the subwoofer, and the upper section is a 35mm pole that slots into the matching cup on the underside of the top speaker.
This is the pro-audio standard, so it fits most mainstream PA subwoofers and top boxes without extra adapters.
The result is a clean vertical stack: subwoofer on the floor for the low end, top speaker lifted to ear or audience level for clear mid and high frequencies.
This unit is telescopic and adjusts from roughly 35 inches up to 54 inches, so the operator can set the top speaker at the right height for the room and the seating.
It is steel for durability under repeated rental use, weighs about 2.5 kg, and carries a typical top-speaker load of 50 to 65 kg, which comfortably handles most 10 to 15 inch passive or active tops.
A safety locking pin holds the height setting and stops the top box slipping when the pole is bumped or vibrating from bass. Height and load are category estimates and are confirmed on the actual unit before dispatch.
