If you're serious about sound, but aren't willing to compromise on style, Sanus Steel Foundation speaker stands were made for you! Combining form and function, each gorgeous stand has a contoured 10-gauge steel base plate with two 2" diameter pillars solidly supporting a steel top plate. Both pillars and top plate feature a handsome black powder-coated finish. But these stands aren't just about good looks. The base plate's stable platform minimizes energy loss from your speaker, giving you better performance. The rounded pillars minimize diffraction, and can be filled with shot or sand for added mass. A resonance-damping ring placed between the top plate and the pillars further improves the speaker's sound. The top plates are equipped with adjustable speaker isolation studs and neoprene isolation pads to dampen unwanted vibrations. The stands come with the Sanus Foundation Mount system, so you can easily secure bolt-style speakers to the top plate.
