In this review, we will be comparing A120P and Minx X201, two Powered Subwoofer speakers from JBL and Cambridge Audio. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of JBL Stage A120P and Cambridge Audio Minx X201 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both JBL Stage A120Pand Cambridge Audio Minx X201 have a single woofer setup however the JBL Stage A120P's woofer is 12-inch whereas the Cambridge Audio Minx X201 features a 6.5-inch woofer.
Frequency Response
A120P has a frequency range of 32-150 Hz whereas Minx X201 has a frequency range of 36-200 Hz. With a minimum frequency of 32Hz, the A120P can go slightly deeper then the Minx X201's min frequency of 36Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
The JBL Stage A120P has a Bass reflex type cabinet. On the other hand the Cambridge Audio Minx X201 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare JBL Stage A120P's and Cambridge Audio Minx X201's external dimensions. JBL Stage A120P has external dimensions of 415.0 x 393.0 x 475.0mm (16-5/16 x 15-7/16 x 18-11/16inch) whereas Cambridge Audio Minx X201 has external dimensions of 220.0 x 210.0 x 256.0mm (8-5/8 x 8-1/4 x 10-1/16inch).
JBL Stage A120P is clearly the larger of the two speakers. Its body is 183mm wider, 195mm taller and 219mm deeper than Cambridge Audio Minx X201.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2 and base area of the Cambridge Audio Minx X201 is approximately 537.6cm2 / 83.3inch2. The A120P requires 247% more surface area than the Minx X201 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The JBL Stage A120P weighs 18.68kg / 41.1lbs and the Cambridge Audio Minx X201 weighs 5.00kg / 11lbs. This makes the A120P 274% heavier than the Minx X201.
Here is a comparison of how A120P and Minx X201's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
JBL Stage A120P needs about 247% more floor area. JBL Stage A120P stands 219mm further into the room. JBL Stage A120P is 195mm taller.

A ported subwoofer against a passive radiator one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | A | JBL Stage A120P goes deeper - 32Hz against 36Hz. A real difference, though most music has little content below 36Hz. |
| Amplifier power | A | JBL Stage A120P has the bigger amplifier - 250W against 200W RMS, about 1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | JBL Stage A120P moves more air: 12" against 6.5" is 3.41x the cone area, not the 1.85x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | JBL Stage A120P is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; Cambridge Audio Minx X201 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Cabinet size | depends | Cambridge Audio Minx X201 is about 85% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Warranty | B | Cambridge Audio Minx X201 carries 3 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | JBL Stage A120P costs less - $300 against $449, about 33% less. |
A JBL Stage A120P B Cambridge Audio Minx X201
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
JBL Stage A120P is the easier recommendation: it leads on most of the measured areas and costs less. Take Cambridge Audio Minx X201 if one of the "depends" rows describes your room. If placement is the constraint - a corner, behind a sofa, under a desk - Cambridge Audio Minx X201 is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
