Our take on the Cambridge Audio Minx S325

Hi-fi surround sound from stylish, compact speakers

Cambridge Audio's S325 system will put you right in the heart of big movie action — without cluttering your home with clunky black boxes. You'll be blown away by the accuracy, detail, and realism from the five tiny satellite speakers that measure less than 6" high and 3" deep. The matching 300-watt subwoofer measures less than a cubic foot, delivering awesome bass without eating into your living space. Whether you're looking to maximize your music or movie experience or add depth to your favorite TV shows and sports, the Minx S325 is waiting to reveal what you've been missing.

Lifestyle shot

"Let me come right out and say it; at this moment in time, Cambridge Audio's Minx system has earned the unofficial title of 'King of the Compact Surround Systems' — at least with respect to any of the competing alternatives I've heard thus far. As far as I'm concerned, it has earned this title through its combination of unexpectedly high levels of refinement and finesse, stouthearted dynamics, exceptionally vivid imaging, and spacious soundstaging — all offered at a more than reasonable price."
—Chris Martens, The Perfect Vision, April 20th, 2011

Ultra-compact satellite speakers engineered with passion

Minx Min 20

The five Minx Min 20 satellite speakers included with this system were carefully designed and tested at Cambridge Audio's London facility by a team fueled with a passion for incredible sound. They completely rewrite the rulebook of what's possible from miniature 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 Min 20s to produce a much wider frequency response than comparably sized speakers. You'll also experience a much broader sound dispersion across your entire room, for the most enveloping sound imaginable. Plus, the compact, acoustically damped cabinets offer extreme rigidity, so you hear pure, clean sound no matter how intense your movies get.

Awesome bass from a hideaway sub

Minx X300

The matching Minx X300 subwoofer uses an 8" forward firing driver made of a single piece of super strong, aerospace-grade aluminum for amazing punch and attack. It's paired with a passive radiator that adds some serious mid-bass boost. Cambridge Audio's software engineers specially designed the sophisticated Digital Signal Processor (DSP) in this sub, allowing it to pump out sensational bass from such a compact enclosure. You may even be fooled into thinking the X300 is several times its size.

Speakers that fit your lifestyle

Quite naturally, you want your speakers to fit into your home, rather than designing your living space around your system. That's why the compact Minx Min 20 satellites can be mounted to your wall, placed on stands, or positioned on a tabletop using optional hardware. You can mix and match by adding additional Minx Min 20 or smaller Minx Min 10 speakers to create an even more engaging 7.1-channel system.

Crutchfield Customer Review (What's this?)

I haven't spent much time with these speakers yet so my initial review is purely based on aesthetics. These speakers are indeed small and are very unobtrusive when hung on a wall. I purchased them in white so they would blend with my light colored walls. My first comment has to do with the grills, they are silver in color and don't give an even appearance when you look at the speaker. In my opinion they look dirty. My wife's assessment is they look thin and you can see the frame beneath - not acceptable for the price of the speaker setup. Next is the mounts, if I bought white speakers why would I be ok with black pivoting mounts? I feel I need to paint them but why should I have to? If you sell white speakers, sell mounts to match. As for sound, it's only been 2 days and from what I read these speakers need time to break in. I'll be back to hopefully bump them up a star but for the moment I am feeling underwhelmed.

Pros: Size

Cons: Finish of grills.

Product Research

Overview: The Cambridge Audio Minx S325 is a 5.1ch speaker system which includes five matching Cambridge Audio Minx MIN20 satellite speakers and the Cambridge Audio X300 powered subwoofer. The Cambridge Audio Minx MIN20 satellite speakers provide accuracy, detail, and realism from compact speakers which only measure 3.125" (w) x 6.125" (h). Their wide dispersion capabilities make it easy to integrate them into any room. The Minx satellite speakers offer table-top, speaker-stand, or wall-mounting solutions. The mated Cambridge Audio X300 powered subwoofer provides deep, accurate bass from its 8" woofer, 8" passive-radiator, and 300 watt (RMS) digital amplifier.

High-Gloss Finish: The Cambridge Audio Minx S325 speaker system is available in a high-gloss black (with black cloth grille) or high-gloss white finish (with silver cloth grille). The black and white high-gloss lacquers are finished to the highest standard using paint application techniques developed by premium automotive manufactures. The black and white lacquer finishes are hard to scratch and easy to clean.

Five Satellite Speakers
Powered Subwoofer

Five Satellite Speakers

BMR (Balanced Mode Radiator) Technology: The Cambridge Audio Minx MIN20 satellite speakers feature dual 2.25" BMR (Balanced Mode Radiator) drivers. The Cambridge Audio BMR drivers utilize 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 satellite speakers 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 dual 2.25" BMR (Balanced Mode Radiator) drivers employ a rubber surround for added durability and excursion.

Neodymium Magnets: The BMR drivers utilize ultra-compact push-pull neodymium magnets for greater efficiency.

Frequency Response: The Cambridge Audio Minx MIN20 satellite speakers feature a 130Hz to 20,000Hz frequency range.

Power Handling: The Cambridge Audio Minx MIN20 satellite speakers can handle 15 to 75 watts (RMS), each.

Acoustically Damped Cabinet: The Minx MIN20 satellite speakers employ an acoustically damped thermo-polymer and extruded aluminum cabinet to prevent distortion caused by resonance and vibration. The enclosure is sealed for greater detail and accuracy. The acoustic suspension enclosure measures only 3.125" square. Each speaker features a detachable cloth grille.

Binding Posts: The Cambridge Audio Minx MIN20 satellite speakers are equipped with a pair of binding post terminals. The binding post terminals will accept bare-wire, pin-connectors, and spade-connectors. The terminals are color-coded (black/red) to distinguish between positive and negative.

Note: The binding post terminals can be removed to allow use of banana plugs (single only). The binding post terminals simply pull out of the back of each speaker, which allows access to banana connector inputs.

Mounting Options: The Cambridge Audio Minx MIN20 satellite speakers can be table-top mounted, wall mounted, or placed on a floor-standing speaker stand.

  • Table-Top Mount: The Minx MIN20 satellite speakers come with four self-adhesive rubber feet (each) to simply place the speakers securely on a table or shelf. There is also an optional Minx Table-Top Stand (779MTSA, sold separately) available, which allows placement on a desk, table, or shelf.
  • Wall Mount: The Minx MIN20s features a rear-mounted 6mm threaded insert which allows you to wall-mount the speakers using the included keyhole-slot adapter, the Cambridge Audio Minx Wall Bracket (779MPWM, sold separately), or other optional wall-mount bracket (sold separately).
  • Speaker Stand: The 6mm threaded inserts on the back of the satellite speakers can be used to attach the speakers to the Cambridge Audio Minx Floor Stands (779MFSW, sold separately).

Powered Subwoofer

Digital Signal Processor (DSP): The Cambridge Audio X300 powered subwoofer features built-in Digital Signal Processing (DSP) which allows for smaller cabinet construction without sacrificing bass response.

300W Amplifier: The Cambridge Audio X300 powered subwoofer is equipped with a 300 watt (RMS) digital amplifier for increased efficiency and reliability.

8" Woofer: The Cambridge Audio X300 powered subwoofer uses a one-piece, aerospace-grade aluminum, front-firing 8" cone woofer to move air with incredible efficiency.

Auxiliary Bass Radiator (ABR): The Cambridge Audio X300 powered subwoofer utilizes a down-firing 8" auxiliary bass radiator (ABR) for greater bass response and better efficiency. The ABR design replaces the need for bass ports to eliminate air noise at higher volume levels.

Frequency Response: The Cambridge Audio X300 powered subwoofer has a rated frequency response of 39-200 Hz.

Controls: The Cambridge Audio X300 powered subwoofer is equipped with the following rear-panel controls.

  • Volume Control: The Cambridge Audio X300 powered subwoofer has a rear-panel rotary volume control to adjust the volume of the subwoofer relative to the other speakers in the system.
  • Crossover Frequency: The Cambridge Audio X300 powered subwoofer offers a continuously variable low-pass filter, adjustable from 50-200 Hz.
  • Phase Adjustment: The subwoofer's phase adjustment allows you to adjust the subwoofer's phase between 0° to 180°. If the bass sounds muddy or unclear, adjusting the phase control can sometimes strengthen the bass performance.
  • Auto On/Off: The X300's Auto On/Off feature will switch the powered subwoofer On and Off automatically by signal detection.

Connections: The Cambridge Audio X300 powered subwoofer is equipped with the following rear-panel connections.

  • RCA Input: The powered subwoofer has gold plated left & right RCA line-level inputs for use with receivers having a subwoofer or stereo preamp output that do not contain their own low-pass crossover. The left channel RCA input doubles as the LFE input, if your receiver has an LFE output and a built-in low-pass crossover.
  • RCA Output: The powered subwoofer's gold-plated left & right RCA line-level outputs allow you to connect (daisy-chain) a second powered subwoofer.
  • Wireless Port: This proprietary 5-pin port is designed to connect the Cambridge Audio Wireless Module (not yet available).
