The sound of Cambridge Audio

Cambridge Audio's Minx Min 21 proves that great, soul-stirring sound can come from incredibly small speakers. Hook a set of these babies up to your home theater system and get ready to hear extraordinary levels of power and sonic refinement that'll send chills down your spine. Designed for hi-fi sound on a low-fi budget, the Minx Min 21 will instantly fill your living space with a tonal quality that has to be heard to be believed. You'll be blown away by the accuracy, detail, and realism from this stacked speaker that measure just 6" high and less than 4" deep. Whether you're looking to maximize your music or movie experience or add depth to your favorite TV shows and sports events, the Minx Min 21 is waiting to reveal what you've been missing.

Cambridge Audio Minx Min 11 Lifestyle shot

Engineered with passion

Building upon the highly regarded original Minx Min 20, Cambridge Audio engineers carefully designed the Minx Min 21 at their London facility to deliver even more refined sound, including greater bass extension for better sonic matching with a powered sub. This overachiever rewrites 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 21 to cover a much wider frequency range 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 cabinet offers extreme rigidity, so you hear pure, clean sound no matter how intense your movies get.

Speakers that fit your lifestyle

Naturally, you want your speakers to fit into your home, rather than having to design your living space around your system. That's why the compact Minx Min 21 satellites can be mounted to your wall, placed on stands, or positioned on a tabletop using optional hardware. You can mix and match between colors, or use the Minx Min 21 models in the front of your room with smaller Minx Min 11s in the back. Just be sure to add a Cambridge Audio powered subwoofer to get full bass impact with your action flicks and video games.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Driver Technology

Minx Satellite Speaker: The Cambridge Audio Minx MIN21 satellite speaker provides accuracy, detail, and realism from a compact speaker. Its wide dispersion capabilities make it easy to integrate into any room. The Cambridge Audio Minx MIN21 is designed to be mated with your choice of Cambridge Audio Minx Subwoofer (779X200W, 779X300W, 779X500W; sold separately).

BMR (Balanced Mode Radiator) Technology: The Cambridge Audio Minx MIN21 satellite speaker features dual 2.25" BMR (Balanced Mode Radiator) drivers. 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 satellite 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.

Frequency Response: The Cambridge Audio Minx MIN21 satellite speaker features a 120Hz to 20,000Hz frequency range.

Power Handling: The Cambridge Audio Minx MIN21 satellite speaker can handle 15 to 50 watts (RMS).

Enclosure Design

Compact Enclosure: The Cambridge Audio Minx MIN21 satellite speaker features a 3.125" (w) x 6.125" (h) x 3.75" (d) enclosure.

Acoustic Suspension: The Minx MIN21 satellite speaker features an acoustic suspension (sealed) enclosure for greater detail and tonal accuracy.

Acoustically Damped Cabinet: The Minx MIN21 satellite speaker employs an acoustically damped thermo-polymer and extruded aluminum cabinet to prevent distortion caused by resonance and vibration.

Removable Grille: The Cambridge Audio Minx MIN21 includes a detachable cloth grille.

High-Gloss Finish: The Minx MIN21 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.

Connections

Binding Posts: The Cambridge Audio Minx MIN21 satellite speaker is 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.

Banana Plugs: The satellite speaker's 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 the speaker, which allows access to banana connector inputs.

Mounting Options

Placement: The speaker can be mounted vertically or horizontally (as center-channel speaker). The speaker should be angled toward the listener, if possible.

Table-Top Mount: The Minx MIN21 satellite speaker comes with four self-adhesive rubber feet to simply place the speaker 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 MIN21 features a rear-mounted 6mm threaded insert which allows you to wall-mount the speaker 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 insert on the back of the satellite speaker can be used to attach the speaker to the Cambridge Audio Minx Floor Stands (779MFSB, sold separately).

Crutchfield Customer Review (What's this?)

Although not cheap, great value and great sound in a small package. Definitely able to fill a family room with a clear, crisp sound!

Family room fit!

Written By Geoff C, Fairfield, CT on Monday, September 29, 2014

Crutchfield Customer Review (What's this?)

Having completed a remodel of the family room we wanted to update our home theater speakers. Purchased a pair of these little dynamos based on the recommendation from a Crutchfield tech person. We were limited on the center channel speaker dimentions given the new design height between fireplace mantel and lower edge of TV so went with a PSB Alpha CLR1 center and were told the Minx min 21s would pair well. (have a couple of options for the sub that i'm still trying). I let them break in for a a while and recently had daughter and friends watching the Nightmare before Christmas. A musical, so plenty of opportunities to hear effects, music, dialog, and so many different characters unusual voices. I know the center was doing lots of work at the same time (it's great, see other review) but the Minx21s as front left and right speakers helped fill the room with rich sound and I never detected anything the least bit tinny or felt that they were lacking the power to fill a good size room (sitting back 12 feet from speakers, and having 12 ft ceilings). I'm not anywhere near an audio geek, but I do love and appreciate great music and great sound. I have the Energy micro theater (5.1) set up for the "man cave" which is a much smaller room. Those sound great in there. These sound just as good in a bigger room.

Pros: Tiny size great sound sleek black design

Cons: none yet perhaps not the greatest if you want room filling tunes from your collection of vinyl

Minx Min 21 Review

Written By Murph, Sacramento, CA on Saturday, July 19, 2014

Crutchfield Customer Review (What's this?)

I am using these speakers as Front Presence speakers in my 9.1 home theater system. They are bright and clear and really add another dimension to the sound produced by my Yamaha Aventage preamp. My wife likes the fact that the speakers are small and fit in well with our family room.

Pros: Size, sound, and price

Cons: Haven't found any as yet

FANTASTIC

Written By Anonymous, San Francisco on Tuesday, May 13, 2014

Crutchfield Customer Review (What's this?)

Great sound from such a small package. Very clear with no distortion even on higher levels. This replaced my 300 series speakers from a decade ago which I loved, but these are far superior in every way. I use them mainly for TV Surround sound , but also use them for music and gaming.

Pros: Small package. Looks. EXTREMELY CLEAR SOUND.

Cons: None so far

so good it's scary

Written By Paul, New Britain, PA on Friday, February 21, 2014

Crutchfield Customer Review (What's this?)

I've been using a Minx 2.1 system (Minx 10's and Minx 200 sub from Crutchfield) for about 2 years as TV speakers, and stereo now and then. Crazy good for TV and movies, acceptable for stereo, but nothing to write home about. I'm using Music Hall amp and CD player, about $1500 for the pair, and I'm pretty particular about having clean sound. Thought I'd upgrade to the Minx 21's to see if there was much difference between the 21's and the 10's for music listening. Out of the box they sounded pretty amazing, a huge leap from the single driver 10's., I couldn't be happier. My room is a converted porch room 12'x16' with hip roof, 14' to the peak. I've had Totem Mites and Arros in there, also Meadowlark Kestrels, even mounted Allison 4's. Nothing sounded great in there except the Minx 21's. Even my wife noticed how great they sound. Go figure.

Go and buy the 21's, but you may want to use them with a larger sub than the 200w Minx sub, depends how loud you like to listen.

Pros: Very wife friendly, I have them mounted on the Minx stands, more efficient than the 10's, the drivers are slightly different, with the top being the conventional Minx driver, and the bottom speaker has a longer throw that puts more growl in the bottom end.

Cons: none

Cambridge Audio Minx Min 21

Written By Mark F., Michigan on Saturday, May 04, 2013

Crutchfield Customer Review (What's this?)

These are probably the best sounding mini speakers out there, but by themselves, they do not do bass. They cast a spacious, detailed soundfield and are great for casual listening.

Pros: compact size, well built, good through the upper frequencies and upper midrange, cast a wide, unified, yet detailed soundfield

Cons: a bit pricey, require a bass module for ful range sounds (but this limitation applies to all compact speakers)

Dialogue sounds cold and highs a bit shrill/harsh

Written By Tennyson, Rocklin, CA on Monday, April 08, 2013

Crutchfield Customer Review (What's this?)

I really wanted to like these, but I've used them for 3 weeks and found movie dialogue to be cold sounding and the highs to be a bit shrill or harsh. The sound quality did improve noticeably after the first week, but was stable after that. The improvement was surprising as I haven't noticed other speakers requiring break-in. The high frequency response is much better than the dual driver Bose cubes (from an acoustimass 15 system), but the dialogue sounds more tinny and cold. The speakers were driven by a Harman Kardon AVR7000. After some experimentation, I found replacing the center speaker of the Bose system with an ESS heil driver greatly improves the high frequency response while also providing clear dialogue. I'm planning to go with this combination rather than use the Minx MIN21's.

Pros: better high frequency response than bose satellites

Cons: dialogue sounds cold/tinny, highs sound a bit harsh/shrill

Thanks for your question. For information on selecting the best speakers for your system I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Jeff  Jan 20, 2014 ]  Staff
Easily. The satellite speakers are great. You may not even need 2 subs. That's more of a personal preference. As long as you have the right a/v receiver you should be good to go with 5 minx 21 speakers. Enjoy! [ CONNOR  Jan 21, 2014 ]
In my opinion they will. As long as the subwoofers are well located and the crossover freq set up correctly for the room, I think you won't regret it, specially at mid-high levels, I find that subwoofer usually lacks at low levels (without having to increase the sub level). You also have to realize that these speakers will sound beautifull but will not play lower than 120 Hz or so, which will limit the subwoofer placement (at least one of the two, depending on your crossover capabilities) due to the ability to locate freq between 80-120hz appvrox. Or whatever croozover freq you end up using (140hz?) In my case I have a 12" sub located next to the tv and I love the setup, if placing the sub close to the front speakers will not work for you, then you might want to consider some bigger speakers than can play down to 80hz and then place the subwoofer somewhere else (i.e. behind couch) These speakers are small but very capable of reproducing beautifull and loud sound.
