Bose Professional 857000-0110 Sub1/Sub2 Adjustable Speaker Pole

Optimize live sound and installation efficiency with the Bose Professional Sub1/Sub2 Adjustable Speaker Pole. This purpose-built pro accessories & mounts solution raises your Bose S1 Pro or F1 Model 812 above the Sub1/Sub2 bass module to deliver clearer projection, fuller frequency balance and wider audience coverage. The telescoping shaft extends up to 52" so you can quickly fine-tune height for stage, corporate AV, house-of-worship or monitoring room applications. Built from stainless steel and finished in matte black, the pole combines durability with professional aesthetics while weighing just 3.4 lb for easy transport. A standard male M20 thread simplifies mounting to compatible modules and speakers, and the included locking pin keeps the assembly stable against vibration during performances or long monitoring shifts. AV integrators, event planners and security/ surveillance teams benefit from faster setups, repeatable placement and improved intelligibility for announcements, paging or live reinforcement. Backed by Bose Professional quality and a 1-year limited warranty, this adjustable speaker pole is an essential add-on for any Sub1/Sub2 system.
