DETAILS
Premium Multi-Room Audio with Marantz MODEL M4 4-Zone Amplifier & B&W CCM684 8" Ceiling Speakers.
This high-performance audio package combines the Marantz MODEL M4 distribution amplifier with eight Bowers & Wilkins CCM684 8" ceiling speakers, creating a powerful four-zone system for residential installations, custom AV setups, and luxury multi-room audio projects.

The Marantz MODEL M4 delivers 8 x 100W of clean Marantz amplification (into 8 ohms), with Bridge Mode available to provide up to 4 x 200W for more demanding applications. HEOS® Built-in allows you to stream music from popular services such as TIDAL, Spotify, and Amazon Music HD to each zone individually or grouped together for seamless whole-home playback. Multiple input options, including four stereo RCA inputs, two optical inputs, and USB ports, make integration simple and flexible.

The Bowers & Wilkins CCM684 ceiling speakers feature an 8" woven glass fibre bass/midrange driver and a pivoting soft dome tweeter for excellent clarity and detail. A three-position EQ switch allows you to optimise off-axis performance, while the QuickDogs™ mounting system ensures fast, secure installation. With their discreet design and high-resolution sound, the CCM684 speakers are the perfect choice for larger rooms or spaces where powerful, detailed sound is required.
Please note: speaker cable is not included in this package but will be available as a recommended add-on under “Frequently Bought Together” on the product page along with fire hoods if required.
