About the Bowers & Wilkins CWM 664 In-Wall Speaker
The CWM 664 is a great entry-level in-wall speaker that will work well for surround channels. It pairs up nicely with the 600 series B&W speakers for your main three channels. The CWM664 uses a 6” glass-fiber midrange/woofer with a 1” soft dome tweeter that uses a variant of B&W’s tapered tweeter found in their more expensive speakers.
Use Cases and Best Practices
The most common use case for in-wall B&W speakers is for the surround channels. In today’s world of object-based surround sound, you want to have your main surrounds and rear surrounds close to ear level. In-wall speakers are perfectly suited for this position as most home theater or media rooms do not have the space to set up large box speakers to the sides and rear of the main seats.
In some cases, you might even use this type of speaker as your main front three speakers. We do recommend if you go this route, not scrimp on the fronts as they are the most important speakers in your theater, especially the center channel.
