The Airmotiv B1+ is a two way, bookshelf monitor loudspeaker, featuring a 32mm Airmotiv folded ribbon tweeter and a 5-1/4” woven fiber woofer. A pair of Airmotiv B1+ monitors can be used in a small, high-quality two-channel system, of a set of five or seven can be used in a high quality surround sound system for a small room installation. Another option would be to use a pair of Airmotiv B1+ monitors for your front left and right speakers, and combine them with Airmotiv E1’s for your surrounds, with or without an additional Airmotiv E1 as a wall mounted center channel speaker.
