Bose Virtually Invisible 191 In-wall speaker

• Stereo Everywhere® speaker performance produces balanced stereo sound over a wide area, unlike conventional home audio speakers that radiate sound mostly in a single direction.
• Articulated Array® speaker design with two precisely positioned full-range drivers (2.5″) provides consistent, lifelike sound over a large listening area.
• Proprietary ported enclosure technology ensures consistent performance regardless of space behind wall. Produces cleaner and deeper low-frequency performance and ensures that lower frequencies are mainly directed into the intended listening area, not into adjoining rooms.
• Rectangular and round speaker grilles included in every box so you can choose to install the shape that best blends into your décor.
• Ease of installation with enclosure that balances easily in your wall during placement. This allows convenient use of both hands to connect the speaker wire and complete the installation
