This video provides product information for the GIK Acoustics Tri-Trap Corner Bass Trap. Descriptions of size, color options, placement and construction are presented. http://gikacoustics.com/product/gik-acoustics-tri-trap/ The Tri-Trap's dimensions are 23" x 16.5" x 16.5" or 580mm x 420mm x 420mm which fits snuggly into any corner making them virtually disappear into the room. Each Tri-Trap stands 47" or 1195mm tall. The Tri-Trap weighs only 15 pounds (6.8kg) which means it's lightweight enough for corner mounting as well. In his review, Tom Andry of Audioholics says, "The GIK Tri-Traps are a no-brainer for the enthusiast that is serious about making their room sound better." As with all our products, the Tri-Trap employs ECOSE technology which is easy on air quality for your room, the environment, and your budget. See www.gikacoustics.com/greensafe for more information.
