Bowers & Wilkins CWM664- 6 Inches, 2-Way In-Wall Speaker (Each)

Key Features

6-inch mid/bass driver + tweeter (2-way design) — provides a balanced reproduction across lows, mids, and highs suitable for music and home theatre use.

In-wall installation design — built for flush mounting inside walls, helping preserve room aesthetics and saving space compared to floor-standing or bookshelf speakers.

Suitable for stereo, home theatre, or distributed audio systems — works well as a main speaker, rear/surround channel, or part of a multi-room/wall-mounted setup.

Compact and discreet look once installed — blends into wall, less obtrusive than traditional speaker cabinets, ideal for minimalist or modern interiors.

Flexibility in system design — since it’s a passive speaker, you can pair it with a wide range of amplifiers or AV receivers to suit your power needs and sound preferences.

Good for both music and movies — 2-way configuration helps deliver clear dialogue, detailed mids/highs, and respectable low-end for everyday listening or movie watching when matched with adequate amplification.

Description

Bowers & Wilkins CWM 664

The CWM664 is an in-wall speaker distinguished by its 25mm (1″) soft dome tweeter. It brings smoother and more detailed high-frequency performance to a package that also includes a woven glass fibre 150mm (6″) bass/ midrange driver and a three-position high-frequency switch to fine-tune the sound. Installation is catered for by a simple and effective QuickDog fixing system. The CWM664 is an elegantly engineered and cost-effective route to high-quality in-wall sound.

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 that if you go this route, to not scrimp on the fronts as they are the most important speakers in your theater, especially the center channel.
