The enclosure allows for easy placement in the wall or ceiling. Speakers come with both rectangular and round grilles, so you can flush-mount your choice to either surface. And when they're painted to match your walls or ceilings, they blend right in.

If you own a Lifestyle® system, you can covertly bring music to another room in your house with the Virtually Invisible® 191 speakers/SA-2 amplifier package. With select Lifestyle® systems and the SA-2 amplifier, you can even have music in one room while a movie or different music plays in another. At the same time, from the same system. If you already own a Lifestyle® system and 191 speakers, simply add an easily concealed SA-2 amplifier and your 191 speakers will connect easily to your Lifestyle® system with a single cable.
