This speaker pole allows you to mount your Bose S1 Pro PA or other compatible system above your Bose Sub1 or Sub2 powered bass module. Just lay your Sub1 or Sub2 on its side and you’ll find an integrated, M20-threaded pole mount. Sub1 and Sub2 (sold separately) combine with virtually any portable PA to deliver powerful bass from a unique RaceTrack driver design that gives your songs full impact and brings any event to life with bold bass.
