Our take on the Cambridge Audio Minx X201

At just under 9" cubed, it's hard to find a subwoofer this powerful that's smaller than the Minx X201. What's so great about that? Its diminutive size will make this sub incredibly easy to place in your living room. Under a side table, in a corner, next to your entertainment stand — you can place it almost anywhere without sacrificing your style. And like all Cambridge Audio Minx speakers, the X201 is carefully designed to deliver the purest sound, whether you're enjoying a live classical concert or an adrenaline-pumping car chase.

Awesome bass from a hideaway sub

At just under 9" cubed, it's hard to find a subwoofer this powerful that's smaller than the Minx X201. What's so great about that? Its diminutive size will make this sub incredibly easy to place in your living room. Under a side table, in a corner, next to your entertainment stand — you can place it almost anywhere without sacrificing your style. And like all Cambridge Audio Minx speakers, the X201 is carefully designed to deliver the purest sound, whether you're enjoying a live classical concert or an adrenaline-pumping car chase.

Engineered with passion

The Minx X201 uses a 6-1/2" forward firing driver made of a single piece of super-strong, aerospace-grade aluminum for amazing punch and attack. It's paired with dual passive radiators that add 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 X201 is several times its size.

Product Highlights:

  • 200-watt RMS amplifier
  • 6-1/2" front-firing woofer and dual 6-1/2" passive radiators
  • one-piece, aerospace-grade aluminum cones move air with incredible efficiency
  • frequency response: 36-200 Hz (-6dB)
  • continuously variable 50-200 Hz crossover
  • specially designed DSP (Digital Signal Processor) for big bass from a small enclosure
  • adjustable phase control
  • line-level/LFE subwoofer inputs and outputs
  • auto on/off mode
  • scratch-resistant high gloss lacquer finish
  • 8-1/4"W x 8-5/8"H x 10-1/16"D
  • weight: 11 lbs.
  • warranty: 5 years speaker, 3 years amp
  • Our 60-day money-back guarantee

What's in the Box:

  • Powered subwoofer
  • Grille (installed)
  • 6' AC power cord
  • Installation Guide
  • Important Safety Instructions

Needed a Sub-Woofer that would fit in a small space but provide signficant bass. To fit is the right spot I needed a sub woofer that was 10inx10inx10 or less; the Cambridge X201 is the perfect size for my setup and fills my 20ftx20fx room with just enough movie bass.

Excellent warmth for Bookshelf Speakers

John from Altoona, PA on 2/21/2019

Crutchfield Customer Review (What's this?)

Have this matched to a pair of Monitor Audio Silver 100 speakers and driven by a Cambridge Topaz SR 20 receiver. The sub is capable of providing low end warmth with a crisp punch. Investing a little set up time on volume, crossover, and appropriate placement can provide amazing results. Well worth the money. Wouldn't recommend it to members of the Head Bangers Ball. It works well for warmth and not vibrating the windows!

Pros: Read the review.

Cons: Not for members of the Head Bangers Ball. It will raddle the windows

Great choice for our medium-size room

Crutchfield customer from Dallas, TX on 2/5/2019

Crutchfield Customer Review (What's this?)

The Minx X201 fills our 300 sq. ft. room with a rich bass response and very smooth transition from higher frequencies. I'm completely satisfied!

Pros: Size, price, performance

Crutchfield Customer Review (What's this?)

I needed a compact subwoofer to fit into my 5.1 system. When I saw that it was from Cambridge audio I knew it would produce what was advertised. Between the Cambridge audio name and the Crutchfield name I was in great hands.



Cambridge Audio Minx X201

Crutchfield customer from New Milford, CT on 7/2/2018

Crutchfield Customer Review (What's this?)

I was surprised by how well this tiny little cube produces bass. It won't shake the house but it definitely provides some "thump" that smaller speakers can't produce. I have this paired with 4 in wall speakers and it helps round out the sound. This is a very good looking unit. I have it placed in the corner of the living room and my fiancé has no issues with the look of it. Major WAF on this one ;)



Great bass for small size

Tiny, Beautiful Sub, Full Sized Sound. No Regrets!

JP from Homer, AK on 5/2/2018

Crutchfield Customer Review (What's this?)

The X201 was for the vanity area at the end of a large master suite, 15 feet wide, 35 feet long with 11 foot high cathedral ceilings. It is so small it sits in the back corner under the vanity seated desk space on the floor without getting in the way. It is paired with two Minx Min 12's on the ceiling above the vanity and an Onkyo stereo receiver under the vanity at about 100W per channel receiving subwoofer preamp out on one RCA phono cable. You may be able to push this sub to the distortion level in a room this big, but you are looking at a very large room, and your neighbors wont' like it that loud. It is nice to have the crossover marked on the back for Min 12's, and also to have the separate volume control. I had to cover the blue standby power light for night time sleep distraction, but that is the only downside to this gutsy tiny speaker, with big clear sound. It is the only solution of it's kind in a package that small, for real quality sound, that I am aware of. I am so glad it comes in white to match decor! It looks good on the white Italian marble style porcelain floor tiles, with a fantastic high gloss finish. Delivery was prompt and FREE TO ALASKA! Thanks Crutchfield, that is such an amazing thing for us to enjoy up here! This sub is not overpriced, it delivers real power and fidelity where you would not think there is space. I have another slated for the guest room, where it will likely fit under the bed, or in a corner of the closet.

Pros: Very nice to look at, something to display, not hide, looks good at eye level on a shelf. Big, tight sound, a bit mind bendingly so for the size, too. Fits about anywhere. Full controls on the back to tune for system needs. Not a toy, even though it is very small for a sub. Great and adjustable for small and medium sized rooms, still adequate for most purposes even in large rooms. Two of these would likely out perform most $700 single subs in a large room, with their superior dispersion.

Cons: You'll need a small square of tape to cover the blue power indicator light on the back for bedrooms at night. One might not be enough for very large rooms if you desire a powerful home theater presence. I wish there were more critical music reviewers writing about the Minx series to compare them, they just sound great to me, but it would be nice to get side by sides with other systems.

Great bass from tiny box

Lucas from Southern California on 4/30/2018

Crutchfield Customer Review (What's this?)

I recently purchased some very tiny bookshelf speakers as main computer speakers and I needed something to fill in the lower ranges. I also needed the smallest sub I could find as this was going under my not so large computer desk. I am very happy with the bass from this device. It has a range that is suitable for these smaller speakers and the sound blends great. I definitely recommend this sub for anyone needing something very small.



Cambridge Audio Minx X201

Mike from Buffalo from Clarence, NY on 4/23/2018

Crutchfield Customer Review (What's this?)

I wanted a smaller sub for my office to go with a desktop system. This sub is incredible! Perfect compliment to monitor audio radius 90 speakers and Marantz M-CR603!

Pros: small on size; big on performance

Cons: none

Amazing small subwoofer

Ron from Timonium, MD on 4/1/2018

Crutchfield Customer Review (What's this?)

I purchased this along with 5 Minx X22 speakers for a new 5.1 configuration in my condo. Had to downsize for this room as it is a 19'x13' and wanted a subwoofer (+ speakers) that would fit into an AV cabinet. The bass response from this subwoofer is amazing, obviously compatible with the X22 speakers, but I am sure would sound great paired with any speakers. Fills the room but not too punchy and doesn't drown out or dominate the sound. I have the volume set at about 40% so there's plenty of power. I was truly skeptical about these speakers at first, but convinced that the sound quality is amazing and glad that I made the purchase.

Pros: Small size, fits in AV cabinet, deep room filling bass but not overpowering.

Cons: None thus far.

Great Sound From a Small Box

Crutchfield customer from Atlanta, GA on 3/25/2018

Crutchfield Customer Review (What's this?)

Impressive sound from a small subwoofer. I have it in a 18x18 living room to use with movies, sports, and music to add base to an in-ceiling speaker surround sound setup. It brings the right amount of base to to bring needed depth to the audio. I dont even have the volume up to high so I know it can get louder if needed. The small size keeps my wife happy because it practically disappears on the built-in shelves.



Perfect to fill out TV sound

Brian from Minneapolis, MN on 2/11/2018

Crutchfield Customer Review (What's this?)

Bought this to compliment the new Sony OLED TV - love the sound from the screen, but really missing below about 150hz. This smaller sub allows adjustment up to 200 and used the mini jack from the TV to allow sub to play with screen speaker. Fantastic TV sound in a 400sq. ft. room without adding a separate sound system. Well built and clean sound. Much more musical than Soundengine S8 sub from my PC that I tried first.

Pros: Clean sound Plenty of punch for TV Well built Attractive finish

Size Matters

Steve from Bridgeton, NJ on 5/29/2017

Crutchfield Customer Review (What's this?)

If you don't have the room for a full size subwoofer or you just don't like the looks of a big black box in your room then the Cambridge Audio Minx X201 is the sub for you. Its performance rivals that of the much larger sub, and it looks good doing it.

Pros: Size, Size, and Size along with performance and price compared to a comparable full size sub.

Cons: None so far

Great deep bass, from a little giant!

Crutchfield customer from San Antonio, TX on 5/17/2017

Crutchfield Customer Review (What's this?)

I am matching the Cambridge x201 with the Audioengine A5+ and the sound is amazing! The depth the sub adds to the speakers makes an already nice set up, sound fuller with the rich lows I had been missing. This sub is very musical, but is also excellent for movies and gaming. Small, but explosive!!

Pros: Easy set up, controls are user friendly, and really adds to an existing 2.0 set with no issues to pair.

Cons: None.

Cambridge Audio Minx X201

Bradford R from Lagrange, GA on 3/30/2017

Crutchfield Customer Review (What's this?)

Great second sub. I needed a sub to fit into a tight space and this does the trick. Small, but great sound. The radiant speakers are a nice touch that broadcast the bass sound on three sides. Powerful at 200 watts. This is perfect if you don't want to have a giant speaker to look cool, but still want a speaker that delivers.

Pros: size, radiant speakers

Cons: size can be misleading

Tiny sub

Crutchfield customer from Zion, IL on 3/15/2017

Crutchfield Customer Review (What's this?)

I gave 4 out of 5 stars because this is not just based on sound. I needed sub to be small out of the way and look decent. I have had a much larger sub that was ridiculous when it came to bass but was also huge and not an attractive piece. This little guy gets it done pretty well, excellent for movies. As a sub for music not so much, I'm ok with that but for anyone thinking they can buy this and get the same sound as a much larger sub it's just not the case.

Pros: Size, looks

Cons: power

Amazing sound from such a small enclosure!

Peter on 9/9/2016

It is quite unbelievable when you open the box, you see this small square cube that is going to be your subwoofer, and immediately you begin to have buyer's remorse and questions such as "Why didn't I purchase a larger ported box subwoofer" or "Did I just make an expensive mistake??". I can set your mind at ease right this moment: you have purchased one of the most cleverly designed amplifiers on the market and you will get outstanding bass response even in a reasonably large room. If you want to destroy walls like that time you had a wall of subwoofers behind your head in your car, you will probably need to spend more a d purchase a different type of subwoofer, a ported box. They can make a house shake, at the expense of clean soundingredients bass. This subwoofer is great to add in to existing speakers, due to the size and generic look of the teeny tiny box (9" cube I believe). I have mine paired with three bookshelf speakers and a pair of older Onkyo satellites that were part of an old 2.1 system. The subwoofer blends in successfully putting out an amazing amount of bass, size notwithstanding. You will not be sorry if you purchase this subwoofer.

Pros: Outstanding sound, size of enclosure, array of controls, warranty, overall design.

Cons: The price is a little high.

Perfect size and amazing base.



Holy Moley!

Brandon from California on 1/15/2016

Crutchfield Customer Review (What's this?)

How does this small subwoofer make that much sound? Seriously, this thing rivals my old Infinity 12 inch sub, and its about 1/8th the size.

Pros: Easy adjustments, crossover dial has icons that show where to set it to match best with the matching Minx satellites, the sound is BIG

Cons: Can't they have a white power cable to go with the white sub? At this price it shouldn't be too much to ask for.

Product Research


200W Amp w/ DSP: The Cambridge Audio X201 powered subwoofer is equipped with a 200 watt (RMS) amplifier with digital signal processing. Cambridge Audio's software engineers have designed a sophisticated Digital Signal Processor (DSP) to provide real-time control of equalization and dynamic range processing for the maximum possible performance while preventing drivers overloading or distorting. This allows the Minx X201 powered subwoofer to handle more power and play louder.

6.5" Woofer + Dual 6.5" Radiators: The Cambridge Audio X201 powered subwoofer uses a front-firing, one-piece, aerospace-grade aluminum 6.5" cone woofer powered by the built-in 200W amplifier and twin side-firing, one-piece, aerospace-grade aluminum 6.5" auxiliary bass radiators. The X201 powered subwoofer uses an ABR system rather than having either an enclosed box (which would require even more power) or a ported design (which would require a bigger cabinet). The result is an extremely efficient and powerful active subwoofer housed in a tiny cabinet.

Controls: The Minx powered subwoofer offers complete rear-panel control of volume, crossover frequency, and phase.

  • Volume Control: The Cambridge Audio X201 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 X201 powered subwoofer offers a continuously variable low-pass filter, adjustable from 50-200 Hz.
  • Phase Adjustment: The powered 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.

Connections: The Cambridge Audio X201 powered subwoofer is fitted with stereo RCA inputs and outputs.

  • RCA Inputs: 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 Outputs: The powered subwoofer's gold-plated left & right RCA line-level outputs allow you to connect (daisy-chain) a second powered subwoofer.

Auto On/Off: The X201's Auto On/Off feature will switch the powered subwoofer On and Off automatically by signal detection.

I dislike subwoofers in that they're giant boxes that take up a bunch of space. But I also recognize they're an important part of making a great audio system. Based on the reviews, this one seems like it packs a good punch for its size, and being white, it will blend in better with the rest of our home decor. [ Walter  Dec 03, 2018 ]
Great reviews, small size, and a nice aesthetic. The advisor I spoke with said it would be a good match for my needs. [ Greg  Sep 12, 2018 ]
We used this amazing X201 subwoofer in a limited space in a small condo kitchen. It sits on a tiny corner shelf just above head height. It looks like a cute piece of modern art, but even though the kitchen is in open air with the dining room, living room, and office, it can easily drive the whole area with powerful, tight bass energy. Can't wait to hear it in our house! Had one damaged in shipping, Crutchfield took immediate care of everything. Both are truly spectacular, no complaints! [ John  Apr 09, 2018 ]

6 questions already asked

Unsure - however, I have it hooked up directly to Sony AE1 OLED TV and it fills out the "screen speaker" wonderfully as it can easily extend up to 180hz (high for a sub) to fill in low sounds the TV cannot produce. [ Brian  Jun 03, 2018 ]
It should. No bookshelf speaker can reproduce the lower audio frequencies as richly as the Minx X201. It's designed to just that and it does so superbly. My application is the same setup; Polk bookshelf speakers with Minx for the lows, and I'm very well pleased. As a side note, for the ultimate ability in matching your system to the room it's located in, I highly recommend the addition of an audio equalizer placed on the input of your main power amp (Tape Monitor functionality on vintage systems). Properly tuned, this will add a new dimension to your listening pleasure. [ Randy  Jun 03, 2018 ]
My regrets, I can't specifically answer your 'pairing' question. Honestly, I don't know what CA SX-50 is... I purchased this cube for its compact size (1st priority) and sound quality (2nd priority) vs more traditionally sized boxes and finally purchase cost (3rd priority). This cube met all 3 criteria. I'm very satisfied with my purchase and 3 months later I wouldn't change my decision. [ John  Jun 03, 2018 ]
I am not seeing any mention of this subwoofer's crossover being active on those outputs. This means that if you use the RCA inputs, you should be able to then use the RCA outputs to send the audio to another device amp to power the speakers. However, if the amp has RCA outputs as well, you may want to run the signal to it first and then to this subwoofer. That would prevent any potential issue of the RCA outputs being limited by the crossover in this subwoofer. I hope this helps! My Bio: [ Paul  Jul 11, 2016 ]  Staff
Keep in mind that low frequency sound waves propagate through walls, floors and ceilings more noticeably than mid and highs. This little sub sounds so good that you'll be temped to crank it up. Just remember to have mercy on your surrounding neighbors. [ Randy  Feb 14, 2018 ]
Well it depends on how loud you play will get loud enough to be noticed. Just turn the volume down. [ BRUNO G  Nov 09, 2017 ]
This should work for an apartment. It is not overpowering but it is smooth. [ Douglas  May 03, 2016 ]
In my case, I have a Denon x4200, so I leave it all to the Audessey Room Correction to set the crossover frq. and level. I set the filter all the way up (200Hz I think) and set the level at 12 o clock. The receiver does the rest. For manual settings it will depend on the model and placement of your main speakers. The sub sounds very good. Low and tight. It is small so you might need a bigger sub or multiple (recommended) sub to fill a large room. My Home Theater is 16x12' and its plenty. Highly recommend. [ BRUNO G  Aug 22, 2018 ]
I don't understand crossover frequency, so I just plugged it in and ran with the factory settings. [ Morris  Aug 22, 2018 ]
I would probably say yes. The exact same thing happened to me with my first subwoofer. Frustrating, but they promptly sent a new one out that works perfectly and I sent the original one back, no problems at all! The 2nd J it works perfectly. Good luck, thx! [ Dale  Mar 26, 2018 ]
I have no problem taking signal from Pre-amp out to the sub. I assume you can verify both that your subout circuit works and that you have sufficient gain in the signal? Can you connect to other output channels to test it? [ Brad  Mar 25, 2018 ]

It did not see any readily visible screws on the feet. [ Jay  Feb 21, 2018 ]
No, they are fixed to the bottom [ Kevin L.  Feb 14, 2018 ]
My best guess is that they're probably glued on since there are no visible screws. They made of a relatively soft material much like silicon that absorbs the vibrations produced by the sub and successfully keeps it from dancing across the floor. The feet are not the least bit "sticky" and have had no ill effect on my hard wood floor. With the speaker facing the front, both sides ported, and controls & connections on the back, there's really no other suitable place for the feet. [ Randy  Feb 14, 2018 ]
Yes [ JACK  Feb 13, 2018 ]
No. It looks like there are stick on rubber feet. You can get some ISO Pucks that work really well. [ BRUNO G  Feb 13, 2018 ]
Swappable with what? [ STEVEN J  Feb 13, 2018 ]
