Cambridge Audio Minx C46 in-hand

The Minx C46's tiny size makes it easy to mount discreetly almost anywhere.

Clear sound from a discreet source

Cambridge Audio created the Minx C46 for people who love great sound but not the clutter of speakers. With a mere 3" mounting diameter, these in-ceiling mighty-mites make a virtually invisible choice for enjoying open, natural sound for music listening, as well as clear movie dialogue and special effects when used as part of a 5.1 surround sound system. Their small size also makes them quick and easy to install, and the grilles can be painted to blend seamlessly into your home. Be sure to add one of Cambridge Audio's powered subwoofers for true, full-range sound with room-filling bass.

Cambridge Audio Minx C46 BMR driver

Cambridge Audio's BMR (Balanced Mode Radiator) disperses sound over a wide area for a more enveloping listening experience.

Engineered with passion

Based on the highly regarded Minx Min 11 satellite speakers, Cambridge Audio engineers carefully designed the Minx C46 at their London facility to deliver refined sound. These speakers rewrite the rulebook of what's possible from miniature in-ceiling speakers thanks to BMR (Balanced Mode Radiator) technology. BMR drivers use a flat speaker surface that combines the traditional "pistonic" movement of speaker cones with a "bending-wave" movement to create sound. It's what allows the Minx C46 to cover a much wider frequency range than comparably sized speakers. You'll also experience much broader sound dispersion across your entire room, for a more enveloping listening experience. Plus, the speaker's compact, integral metal enclosure provides consistent performance wherever you mount them while reducing sound leakage into adjacent rooms.

small but powerful

Written by: Colonel from California on November 17, 2015

Crutchfield Customer Review (What's this?)

These are small 3" diameter speakers. They were chosen for the aesthetics of their small size. They are the same size as the recessed can lights in this renovation. For their size, they do a good job of providing background music. Not a lot of bass but not bad,

Pros: small size, good tone

Cons: not a lot of bass

Awesome Speakers!

Crutchfield Customer Review (What's this?)

These are great surround speakers! I was pleased with the ease of installation and the sound quality. For such a small speakers, they can really put out some great sound. I paired these with Aeromax 2's for the front channels and a Aero 5 center and a Minx X200 sub. I am more than pleased with the quality of these speakers and Cambridge Audio overall.

Pros: Great sound from a small speaker, very good for surround speakers, easy installation in ceiling.

Cons: None.

Product Research


BMR (Balanced Mode Radiator) Technology: The Cambridge Audio Minx C46 in-ceiling speaker features a single 2.25" BMR (Balanced Mode Radiator) driver. The Cambridge Audio BMR driver utilizes patented 'bending wave' principles normally seen in advanced flat-panel speakers, combined with piston-movement (backwards and forwards) like in a traditional speaker design. This type of design provides the Minx in-ceiling speaker with a much wider frequency response and deeper and more powerful bass frequencies, plus incredibly spacious sound. The BMR driver design also adds value by delivering a much broader sound dispersion across the entire room, avoiding the typical "sweet spot" pitfall, for a more enveloping sound.

  • Rubber Surround: The 2.25" BMR (Balanced Mode Radiator) driver employs a rubber surround for added durability and excursion.
  • Neodymium Magnets: The BMR driver utilizes ultra-compact push-pull neodymium magnets for greater efficiency.

IP65 Certified: Fully tested to IP65, the Minx C46 in-ceiling speaker is suitable for high humidity and dusty environments. Its IP65 rating ensures that no dust or water can pass-through and a fitted gasket swells under exposure to heat to block smoke.

Magnetic Grille: The Minx C46 includes a magnetic mesh metal grille that is paintable.

Spring-Clip Speaker Terminals: The Cambridge Audio Minx C46 in-ceiling speaker is fitted with spring-clip speakers terminals to attach your in-wall speaker. The spring-clip terminals will accept bare wire (up to 16AWG) and pin-connectors.

Mounting Options: The Minx C46 in-ceiling speaker requires a cut-out of 3" in diameter and mounting depth 3.75" of depth. Two spring-loaded mounting clips (one on either side of the Minx C46) secures the speaker in the ceiling. The Minx C46 in-ceiling speaker will fit into a standard 3" ceiling spotlight mounting hole.

Applications: The Cambridge Audio Minx C46 in-ceiling speaker is incredibly versatile and can be used as a virtually invisible surround speaker solution as part of a Minx 5.1 system, installed around your home to bring music discreetly to every room, or used in arrays in a commercial environment to provide an even spread of sound.
