In this review, we will be comparing Defiance S10 and Defiance V12, two Powered Subwoofer speakers by Paradigm. 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 S10 and Paradigm Defiance V12 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 S10and Paradigm Defiance V12 have a single woofer setup however the Paradigm Defiance S10's woofer is 10-inch whereas the Paradigm Defiance V12 features a 12-inch woofer.
Frequency Response
Defiance S10 has a frequency range of 25-200 Hz whereas Defiance V12 has a frequency range of 23-200 Hz. With a minimum frequency of 23Hz, the Defiance V12 can go slightly deeper then the Defiance S10's min frequency of 25Hz.
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 Paradigm Defiance S10's and Paradigm Defiance V12's external dimensions. Paradigm Defiance S10 has external dimensions of 338.1 x 342.9 x 425.5mm () whereas 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).
Paradigm Defiance V12 is clearly the larger of the two speakers. Its body is 78.1mm wider, 116.9mm taller and 60.5mm deeper than Paradigm Defiance S10.
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.
Paradigm Defiance V12 needs about 40% more floor or shelf area. Paradigm Defiance V12 is 61mm deeper, so it stands that much further out from the wall. Paradigm Defiance V12 is 117mm 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 Paradigm Defiance S10 is approximately 1459.0cm2 / 226.1inch2 and base area of the Paradigm Defiance V12 is approximately 2046.1cm2 / 317.1inch2. The Defiance S10 requires 29% less surface area than the Defiance V12 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 S10 weighs 15.74kg / 34.6lbs and the Paradigm Defiance V12 weighs 19.09kg / 42lbs. This makes the Defiance V12 21% heavier than the Defiance S10.
Here is a comparison of how Defiance S10 and Defiance V12's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed 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 | evenly matched | Effectively the same reach (25Hz vs 23Hz). |
| Amplifier power | A | Paradigm Defiance S10 has the bigger amplifier - 500W against 120W RMS, about 6.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Paradigm Defiance V12 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Paradigm Defiance S10 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Paradigm Defiance V12 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 | Paradigm Defiance S10 is about 47% 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 | B | Paradigm Defiance V12 costs less - $779 against $1,200, about 35% less. |
A Paradigm Defiance S10 B Paradigm Defiance V12
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. Films or music? If this is mainly a home cinema, Paradigm Defiance V12 will hit harder for the money; if it is mainly for music in a normal-sized room, Paradigm Defiance S10 is usually the easier one to make sound right. 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 $1,200 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.
