The Ultimate Support TS-90B Lift-Assist Tripod Speaker Stand is extraordinarily strong yet lightweight due to its over-sized heavy wall aluminum tubing. They're everything you'd expect from an Ultimate Support speaker stand - they're strong, sturdy, lightweight, 100% field serviceable, and easy to set up and take down. However, the TeleLock collar gives the user the ability to safely raise or lower the stand WHILE a speaker is on it thanks to the Auto-lock technology that securely grips the telescoping tube in place as you set its height.

The TS-90 is one of the easiest speaker stands to use thanks to its patented TeleLock collar. Set the TeleLock collar to either the "Raise" or "Lower" setting and the Auto-lock technology provides just the right amount of resistance to allow you to raise or lower the speaker while locking the tube in place as you go. It's like having tour support built into your speaker stand!

The TS-90'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.

The entire stand (legs, mast, and telescoping tube) uses oversized, heavy-walled aluminum tubing for durability, functionality, and weight savings. The TS-90 will not rust or corrode (thanks to its architectural anodized finish), is very smooth to operate, and is extraordinarily strong yet lightweight.
