About the Cambridge Audio Minx X201

Dave Bar

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 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. These RCA outputs pass-through a full-range audio signal and are unaltered by the powered sub's volume, crossover, or phase control settings.

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

Will the Cambridge Audio Minx X201 subwoofer connect/work with a Yamaha R-N303 receiver?
robert  Jan 07, 2023
1 answer
This subwoofer could not be connected directly to the R-N303. It would be necessary to either select a subwoofer with speaker-level inputs or use a line-output converter such as the Russound ADP-1.2 linked below:
zachary  Jan 08, 2023 (Staff)
If I'm connecting this to my Denon DRA-800H, do I need a Y cable, or just one cable to the LFE/Sub?
gratefulhops  Jan 07, 2023
1 answer
A Y-adapter will not be necessary. A single-channel connection between one of the two subwoofer RCA outputs of the DRA-800H can go to the LFE input of this subwoofer.
zachary  Jan 08, 2023 (Staff)
Does it come with any cables? Looking to fit it into Rec Out on the amp.
fhayes  Jan 18, 2022
3 answers
It did not come with cables. I bought a cable for " sub out " on my amp when I bought the Minx.
steve  Jan 18, 2022
Doesn't come with cables, doesn't go into Rec Out on the amp.
thomas  Jan 18, 2022
I don't recall if mine came with them. But I would never use supplied cables regardless. They are usually of very cheap construction and nicer ones can be had for not much money. Note that rec out on many amps are not controlled by the level control so be sure to check that first.

Is it sealed or ported?
quand  Jun 12, 2019

The Minx X201 is sealed.
michael  Jun 12, 2019
Sealed. The sides are the "radiators" that flex with the movement of the driver. The driver is behind the grill.
lucas  Jun 12, 2019
It's actually sealed and ported. The woofer is pointing forward (not visible, behind the cloth grill) and ported on both, adjacent sides. However, the ports are equipped with flexible aluminum port inserts (visible in the photos) that serve to capture the sound and rebroadcast it. I had not seen this done before, but it works very well in this particular application. I have a larger, down-firing Infinity sub downstairs that I like a lot. That being the case, I was concerned about whether or not the relatively small size of the Minx could reproduce a good bass sound. To my surprise (and relief) it's capable of holding its own against the big boys. So, unless you're wanting to constantly rattle the windows and doors, this little guy should be able to make you happy.
randy  Jun 12, 2019
The unit is sealed and has an active and passive radiator. Amazing sound for a unit this small.
lawrence  Jun 12, 2019
Would this pair well with CA SX-50?
jeffrey  May 18, 2018
3 answers
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
Can I use the RCA out to go into an amp to drive bookshelves?
richard  Jul 08, 2016
1 answer
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:

Is it apartment friendly (e.g. will I get evicted for noise violations)? :)
jeff  May 02, 2016
3 answers
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.

Will this sub work well with a bluesound node? Pairing with a set of KLH model 5s
victor  May 30, 2023
1 answer
The Cambridge Audio Minx X201 would work very well, Victor. The Minx can reach lower frequencies than the KLH are capable of playing, and it has an extremely small physical size that can fit almost anywhere. Do not forget to grab the SVS SoundPath mono RCA in the link below so you can connect to your Bluesound Node's subwoofer output! The link below is for the 6.5-foot version, we have them available in longer lengths if needed to fit your specific setup.

Can I connect this sub to a Leak 130? Will it work?
mark  Feb 18, 2023
1 answer
It would be possible to connect the LEAK 130's RCA preouts to the input of the Minx X201. This would work nicely.
zachary  Feb 19, 2023 (Staff)
Have 8.5 inches of vertical space for this item. Could an owner confirm that this thing will actually fit?
andrew  Mar 12, 2022
4 answers
It might be possible but ... I just 'taped' mine to be sure I am being accurate. The actual enclosure is 8 1/4" x 8 1/4", but with the bottom feet it becomes 8 7/8" high. I guess you could 'trim' the bottom feet a bit to fit, but I would hesitate to remove them completely to prevent unwanted vibrations wherever you are placing it. But, perhaps I am being too conservative ... I will say that it is a 'solid' performer and punches above its weight ... Mine is in a 12' x 12' room with 9' ceilings sitting on the floor which is ceramic tile over a slab foundation. I have never played music that approached spec volume limits. I do also like the variable crossover settings and there are 'icons' for the matching single and dual speaker Minx Min speakers. Right now it is paired with Minx Min22s on Minx Floor Stands, but should I want to change out the stereo pair for a different set in the future, the variable crossover can be set to a different point.
david  Mar 12, 2022
Mine is 8.5 inches tall including the isolating feet, if not a 1/16th over. It would be tight. The feet do not seem to be detachable either.
jason  Mar 12, 2022
It's going to be tight - I measured it twice, - it should just barely fit. I would say go ahead and buy it it (it's a very nice sub), but note the controls are on the back and there is no remote. Btw, Crutchfield is excellent with their returns, if it doesn't work out.
conrad  Mar 12, 2022
I have the unit and it is great at filling in some bass for a 5.1 system in our family room. Re height mine is 8 and 9/16". Maybe try it and if it doesn't fit use the free 30 day return policy ? There are 4 little rubber feet on the bottom but they do not look to be easily removable. Good luck.

Yes you can (Sub Out on receiver to LFE/Sub in on the Minx.

As long as your receiver has a "subwoofer" out ... Yes! Mine is connected to a vintage Pioneer Technics receiver ...

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
It's not working - I can't identify where I could be going wrong. I'm using a proper subwoofer cable; indeed, I have tried out two different brand-new cables. I'm connecting the subwoofer cable from the "SUB OUT" on my receiver, and plugging it into the Left RCA input, as the instructions indicate. The unit is powered, the LED indicator light on the back is on, the volume is not zeroed out, and I've tried going up and down the phase and freq crossover dials. There is simply zero output. Do I just have a dud unit?
david  Mar 11, 2018
4 answers
This answer may not help the person from the original post, but maybe future purchasers. Many new receivers have settings for your speaker configuration - this turns off/on some of the outputs and allows the amplifier to optimize for the speakers you are using. For example, if the setting is configured for 2.0, the center channel, rear surrounds, and subwoofer outputs will not work. So if you plug speakers into your receiver (including a subwoofer), and you don't get any sound - check to see if your receiver has a speaker configuration setting. (I certainly know many of the newer Sony receivers do this).
brian  Feb 25, 2023
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

Do the feet screw on and off, are they swappable?
david  Feb 13, 2018
6 answers
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
jack  Feb 13, 2018
No. It looks like there are stick on rubber feet. You can get some ISO Pucks that work really well.
