The TS-110 speaker is part of Ultimate Support"s Air-Powered Series speaker stands. It"s incredibly strong, extraordinarily sturdy, lightweight, 100% field serviceable, and makes it easy to raise and lower speaker stands on their own. Driven by innovation and years of research and development, the Air-Powered Series stands like the TS-110 feature an internal shock that lifts speakers weighing 50 pounds and less with no effort, and requires just one hand"s worth of effort to raise speakers weighing more than 50 pounds. Not only does the TS-110 offer you extra height, but it also comes with 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-100 is an incredibly easy-to-use speaker stand thanks to the internal air-powered shock that literally raises the speaker for you. The stand"s internal shock easily raises speakers weighing 50 pounds and less with no effort from you and requires only minimal to raise speakers weighing more than 50 pounds. When you"re ready to lower the speaker, a convenient and ergonomic hand grip let"s you lower the speaker with just one hand. It makes setting up and tearing down speakers. Leveling leg included Have you ever run into a situation when you wished you could place a speaker where a set of stairs, risers, or a short ledge was in the way? The TS-110 includes one leveling leg that telescopes down an additional 13" beyond the length of the other two tripod legs allowing you to place the TS-110 on a set of stairs, risers, or hillside, etc. Extra height The original TS-100 is plenty tall enough for most normal situations. However, when you need to get your speaker, lighting tree, light truss, or whatever, up a little higher, the TS-110 is the perfect stand for you. The TS-110 adds about 26 inches of additional height and has a maximum height of 9" 2"! Patented Tripod Design The TS-110"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. Oversized 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-110 will not rust or corrode (thanks to its architectural anodized finish), is very smooth to operate, and is extraordinarily strong yet lightweight.Raise and lower the speaker with ease Leveling leg included Extra height Patented tripod design Oversized heavy wall aluminum tubing 100% field-serviceable parts Height: 5"2"- 9"2" (1575mm - 2794mm) Weight: 13.5 lbs.
