One of the greatest aspects of the RoomMatch speaker system is the ability to specify exactly the right coverage angles. Recognizing that sometimes an asymmetrical box would be better, Bose came up with some of those too. And for under-balcony fills, or even stage monitors, a new utility speaker, the RU8 is available. For better low end, a new dual 18" sub now pumps out the bass. For more information, visit the Bose Pro Website.
