Speakers can be purchased as a package (5.1 and 7.1) or separately. There are a lot of brands to choose from, each with its own unique sonic signature. Depending on the aesthetics of your home theater or living room, you can pick between traditional box speakers that are visible to viewers, or choose in-wall and in-ceiling speakers that disappear into the ceiling and walls. If you choose the latter, some drilling, cutting and running speaker cable is required. If this sounds overwhelming, don’t worry. A THX Certified Professional can help with speaker installation.
Today, there are a number of great THX Certified in-wall and in-ceiling speakers that deliver the same, solid performance as THX Certified box speakers. Companies such as Sonance, Klipsch, Polk Audio and Atlantic Technology, have raised the bar for in-wall/in-ceiling performance.”
