Features: Air-Powered Series speaker stands from Ultimate Support represent everything all other speaker stands aspire to be. They're incredibly strong; extraordinarily sturdy; lightweight; 100% field serviceable; AND raise and lower speaker stands on their own! Driven by innovation and years of research and development; the Air-Powered Series feature an internal shock that lifts speakers weighing 50 lbs. and less with no effort; and requires just one hand's worth of effort to raise speakers weighing more than 50 lbs.! There are three models to choose from: the TS-100B; TS-110B which offers additional height; and the TS-110BL which also offers additional height plus a leveling leg that allows the speaker stand to stay level on risers; stairs; and other uneven surfaces. Raise and Lower the Speaker with Ease! The TS-100B is the easiest speaker stand to use thanks to the internal air-powered shock that literally raises the speaker for you. The stand's internal shock easily raises speakers weighing 50 lbs. and less with no effort from the user. And; the TS-100B requires very little effort from the end user to raise speakers weighing more than 50 lbs. When you're ready to lower the speaker; we've provided a convenient and ergonomic handgrip from which you can lower the speaker - with just one hand. There's never been an easier; more convenient; or safer way to set up and tear down speakers. Patented Tripod Design The TS-100B's offset tripod base design provides more support than typical "off-the-shelf" speaker stands. The design makes for very tight internal fittings; doing away with unnecessary sloppy leg problems; and includes a super strong die-cast metal collar that prevents over-tightening and breakage issues associated with all plastic designs. Over-sized Heavy Wall Aluminum Tubing The entire stand (legs; mast; and telescoping tube) uses oversized; heavy-walled aluminum tubing for durability; functionality; and weight savings. The TS-100B will not rust or corrode (thanks to its architectural anodized finish); is very smooth to operate; and is extraordinarily strong yet lightweight. 100% Field Serviceable Parts From the foot caps on the bottom of the tripod legs all the way up to the speaker adapter at the top of the stand; the TS-100B is serviceable by parts as needed over its very long lifespan. In the unlikely event that something does break on the TS-100; simply replace with an affordable part instead of throwing the entire stand away and buying a whole new one!
