The Boston Acoustics VSi 555W2 is a compact 2-way LCR speaker designed for discreet installation in walls. The speaker has a pair of 5.25" DCD copolymer woofers with die-cast baskets and a 1" aluminum VR tweeter 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.
