Bose® Virtually Invisible® 891
Our take on the Bose® Virtually Invisible® 891 by Crutchfield's Eric Angevine
Bose® Virtually Invisible® speakers provide excellent sound and blend into any decor.
Bose's best in-wall speaker delivers solid bass
Bose calls these speakers Virtually Invisible because they're designed to blend into any decor. Enjoy music and movie sound effects and dialogue from out of the way speakers. Each Bose® Virtually Invisible® 891 speaker has a 7" woofer to deliver rich low frequencies, and two strategically positioned 1" tweeters to direct crisp, clear mids and highs to your ears. Exclusive Bose Stereo Everywhere design provides balanced stereo sound over a wider area, with no drop-offs.
The speakers are easy to install in your walls, and they come with a pair of rectangular grilles that attach magnetically. The grilles and grille frames are finished in white, but are paintable to match your decor.

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.

Wanted it [ Walt Apr 23, 2017 ]
woofer size speakers [ William Mar 04, 2017 ]
I wanted two speakers for the kitchen and they came as a pair. I have 4 Bose 601 speakers I bought in 1979 and they are still working to this day. I have been very pleased with the Bose 601 speakers. So I thought I would give these wall mount speakers a try. [ Joe Mar 02, 2017 ]
I have always been impressed with BOSE quality and have had successful dealings with Crutchfield in the past. [ Frank Dec 10, 2015 ]
4 questions already asked
Worked really well in my basement, but I wouldn't use them outside. They have no enclosure. [ jj Aug 05, 2017 ]
Given how they're designed to install, you should be able to mount them horizontally just as easily as you would vertically. If you would like to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

I am using the Bise 891 as front speakers on my home theater. They would make great rear speakers as well . Not so sure about center Chanel. Check Bose for a center Chanel speaker. [ michael Jun 16, 2017 ]
I am planning to paint them with laquer and a low preasure gun. To light coats should work. I've done this with other covers and it worked just fine. [ Kenneth Mar 02, 2016 ]
