Virtually Invisible in-wall Speakers: The Bose Virtually Invisible 691 in-wall speakers are engineered with one 7" woofer and two strategically positioned 1" tweeters each, eliminating the need to aim the speaker into the room. The acoustic design allows for full, even sound coverage, while their smaller size increases placement options. Exclusive Bose "Stereo Everywhere" speaker performance provides balanced stereo sound over a wider area, with no drop-offs.
Stereo Everywhere Speaker Performance: "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. Bose "Stereo Everywhere" speaker performance delivers sound evenly throughout the listening area for balanced stereo sound wherever you listen, not just in one sweet-spot.
Drivers: The combination of two 1" dome tweeters and a 7" high-excursion woofer provides spacious stereo sound for your favorite music. You will also enjoy the deep low notes of dramatic movie sound effects. This makes 691 speakers ideal for a rear-channel option in a home theater setup. The tweeters are strategically positioned to eliminate the need to aim the speakers into the room.
- 7" Woofer: A 7" high-excursion woofer delivers deeper low notes for more dramatic movie sound effects and musical richness.
- Dual Angled 1" Tweeters: Two strategically positioned 1" tweeters (array configuration) in each speaker eliminate the need to "aim" the speakers into the room. This lets you arrange your room with greater freedom.
Spring-Post Terminals: The Bose Virtually Invisible 691 in-wall speaker use spring-post terminals to connect your speaker wire (18-14AWG).
In-wall Installation: The Bose Virtually Invisible 691 in-wall speakers offer simplified installation with only four clamp screws that secure each 691 speaker to your drywall. The 691-series speakers also feature an infinite baffle design that uses the wall as the speaker enclosure. The infinite baffle design eliminates the need for a separate speaker enclosure, so it uses the space inside the wall instead. Once you have positioned the speakers, just tighten the clamp screws and snap the magnetic grilles into place. The finished looked is unobtrusive, and almost invisible. You can even paint the speaker grilles to match your décor.
Note: Virtually Invisible 691 speakers are designed for in-wall installation only. Virtually Invisible 691 speakers can only be installed in wood frame construction covered with wallboard made of gypsum, plaster and lath, paneling or similar construction.
Paintable Grilles: The ultra slim bezel is attached directly to the speaker grille, allowing them to be easily painted in one simple step and blend elegantly into the room. And with no cloth scrim, there's no worry of excess paint clumping or soaking in. Paint masks are included to protect the speaker cones. Plus, magnets allow them to snap on and off quickly.
Cutout Template: Cutout templates are not included in the box, therefore, you will need to print a template from the manual linked from the Crutchfield website, or from Bose.com. You must make sure the template is printed at 100%, and not enlarged or reduced. The measurements on the template are expressed in millimeters, but a 1" scale is provided to make sure it is printed to scale.
