In this review, we will be comparing Defiance V12 and SW-15, two Powered Subwoofer speakers from Paradigm 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 Paradigm Defiance V12 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 Paradigm Defiance V12and Wharfedale SW-15 have a single woofer setup however the Paradigm Defiance V12's woofer is 12-inch whereas the Wharfedale SW-15 features a 15-inch woofer.
Frequency Response
Defiance V12 has a frequency range of 23-200 Hz whereas SW-15 has a frequency range of 30-120 Hz. With a minimum frequency of 23Hz, the Defiance V12 can go significantly deeper on the low side and provide stronger bass compared to the SW-15's min frequency of 30Hz.
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
Both Paradigm Defiance V12 and Wharfedale SW-15 have Bass Reflex type cabinets. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the 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 Paradigm Defiance V12's and Wharfedale SW-15's external dimensions. Paradigm Defiance V12 has external dimensions of 455.0 x 421.0 x 486.0mm (17-7/8inch x 16-9/16inch x 19-1/8inch) 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 72mm wider, 115mm taller and 129mm deeper than Paradigm Defiance V12.
Below you can see the front view size comparison of Paradigm Defiance V12 and Wharfedale SW-15 in scale.

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 Paradigm Defiance V12 is approximately 2046.1cm2 / 317.1inch2 and base area of the Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2. The Defiance V12 requires 33% 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 Paradigm Defiance V12 weighs 19.09kg / 42lbs and the Wharfedale SW-15 weighs 31.57kg / 69.5lbs. This makes the SW-15 65% heavier than the Defiance V12.
Here is a comparison of how Defiance V12 and SW-15'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.
Wharfedale SW-15 needs about 48% more floor area. Wharfedale SW-15 stands 129mm further into the room. Wharfedale SW-15 is 115mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | A | Paradigm Defiance V12 goes deeper - 23Hz against 30Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | B | Wharfedale SW-15 has the bigger amplifier - 400W against 120W RMS, about 5.2dB 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 12" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Speaker-level inputs | A | Paradigm Defiance V12 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Wireless option | depends | Only Paradigm Defiance V12 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Cabinet size | depends | Paradigm Defiance V12 is about 46% 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. |
| Price | A | Paradigm Defiance V12 costs less - $779 against $1,199, about 35% less. |
A Paradigm Defiance V12 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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. Check your amplifier first: if it has no subwoofer or preamp output, Paradigm Defiance V12 is the only one of these two you can connect at all. 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 $779 each, two Paradigm Defiance V12 cost about $1,558 against $1,199 for one of the other, which is worth a thought.
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.
