The Boston Acoustics VSi 580T2 is a compact 2-way stereo speaker designed for discreet installation in walls or ceilings. The speaker has an 8" DCD copolymer woofer with a die-cast basket and a pair of 1" aluminum VR tweeters to deliver crisp, realistic audio with a wide frequency response. The speaker is designed for easy installation, with a reduced bezel design for seamless integration, a paintable surface to match your decor and a magnetic grille. A boundary compensation switch allows you to tailor the speaker's sound to counteract the effects of being installed too close or far from a corner. The result is optimum sound quality, regardless of installation location.
