In this review, we will be comparing MSX Sub 200 and SW-15, two Powered Subwoofer speakers from Cambridge Audio and Wharfedale. 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 Cambridge Audio MSX Sub 200 and Wharfedale SW-15 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 Cambridge Audio MSX Sub 200and Wharfedale SW-15 have a single woofer setup however the Cambridge Audio MSX Sub 200's woofer is 6.5-inch whereas the Wharfedale SW-15 features a 15-inch woofer.
Frequency Response
MSX Sub 200 has a frequency range of 36-200 Hz whereas SW-15 has a frequency range of 30-120 Hz. With a minimum frequency of 30Hz, the SW-15 can go significantly deeper on the low side and provide stronger bass compared to the MSX Sub 200'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.

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 Cambridge Audio MSX Sub 200's and Wharfedale SW-15's external dimensions. Cambridge Audio MSX Sub 200 has external dimensions of 217.5 x 209.6 x 257.2mm () whereas Wharfedale SW-15 has external dimensions of 570.0 x 493.0 x 615.0mm (22-7/16inch x 19-3/8inch x 24-3/16inch).
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 283.4mm wider, 352.5mm taller and 357.8mm deeper than Cambridge Audio MSX Sub 200.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Wharfedale SW-15 needs about 462% more floor or shelf area. Wharfedale SW-15 is 358mm deeper, so it stands that much further out from the wall. Wharfedale SW-15 is 353mm taller.
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 Cambridge Audio MSX Sub 200 is approximately 539.1cm2 / 83.6inch2 and base area of the Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2. The MSX Sub 200 requires 82% less surface area than the SW-15 which gives it a small advantage 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 Cambridge Audio MSX Sub 200 weighs 4.99kg / 11lbs and the Wharfedale SW-15 weighs 31.57kg / 69.5lbs. This makes the SW-15 533% heavier than the MSX Sub 200.
Here is a comparison of how MSX Sub 200 and SW-15's weights compare with the average, max and min weights in Powered Subwoofer class.

A passive radiator subwoofer against a ported 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 | B | Wharfedale SW-15 goes deeper - 30Hz against 36Hz. A real difference, though most music has little content below 36Hz. |
| Amplifier power | B | Wharfedale SW-15 has the bigger amplifier - 400W against 200W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Wharfedale SW-15 moves more air: 15" against 6.5" is 5.33x the cone area, not the 2.31x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Cambridge Audio MSX Sub 200 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; Wharfedale SW-15 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. 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 MSX Sub 200 is about 93% 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 | Wharfedale SW-15 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | Cambridge Audio MSX Sub 200 costs less - $449 against $1,199, about 63% less. |
A Cambridge Audio MSX Sub 200 B Wharfedale SW-15
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?
The usual trade-off: Wharfedale SW-15 measures better, Cambridge Audio MSX Sub 200 costs about 63% less. In a normal room, placement will make a bigger difference than the gap between these two. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $449 each, two Cambridge Audio MSX Sub 200 cost about $898 against $1,199 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Cambridge Audio MSX Sub 200 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.
