High-quality, high-power Angstrom home theater subwoofer. Lesser known, high-end Canadian manufacturer Angstrom has an excellent reputation for attention to detail and engineering. The speaker weighs 47lbs and is seriously powerful (120w - 400w peak amplification). The TEN i is great for medium to large rooms, pairs excellent for music or movies, and is easily one of THE best subwoofer's I have auditioned. Selling due to move, located in the Broadmead area ~ originally $1200. Similar quality and performance to Velodyne, B&W, PSB, Polk Audio, Mission https://www.usahifi.com/sites/default/files/product/518/manuals/Angstrom%20Loudspeakers%20Modular%20System%20Brochure.pdf
