Any good speaker can be used to reproduce one of the surround channels in your configuration. Of course, the more that speaker sounds like your front three speakers, the easier it is to maintain a three-dimensional soundscape where sounds blend as they move around the room, instead of distract.
All of our Cinema Series speakers are timbre-matched so that you can mix and match models throughout your room and maintain a consistent performance. Similarly, choosing speakers exclusively from our HDX in-wall and in-ceiling speaker line will also promote a cohesive soundscape.
But while matching the front three channels is essential for cohesive imaging, and timbre-matching across all speakers is ideal, real-world room layouts and design choices often call for a mix of speaker styles. So if your room dictates speakers from both our cabinet-style Cinema Series and in-wall/ceiling HDX line, rest easy knowing they've been voiced with a shared acoustic philosophy and will always deliver a complementary sound experience.
