We all like being lazy every now and then, and when it comes to raising a heavy speaker on a stand, that can be challenging. Ultimate Support wants to make that easier with the TS100B, an incredibly strong, extraordinarily sturdy, and lightweight speaker pole from their Air-Powered series that's able to raise and lower on its own! These speaker stands feature an internal shock that lifts speakers weighing 35 lbs. and less with no effort, and only requires one hand to raise any other speakers weighing more than 35 lbs.FeaturesRaise and Lower the Speaker with EasePatented Tripod DesignOver-Sized Heavy Wall Aluminum Tubing100% Field Serviceable PartsSpecificationsHeight: 3'8" - 6'7" (1118mm - 2007mm)Weight: 10 lbs.
