In this review, we will be comparing Defiance V8 and Defiance V10, 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 V8 and Paradigm Defiance V10 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 V8and Paradigm Defiance V10 have a single woofer setup however the Paradigm Defiance V8's woofer is 8-inch whereas the Paradigm Defiance V10 features a 10-inch woofer.
Frequency Response
Defiance V8 has a frequency range of 34-200 Hz whereas Defiance V10 has a frequency range of 29-200 Hz. With a minimum frequency of 29Hz, the Defiance V10 can go significantly deeper on the low side and provide stronger bass compared to the Defiance V8's min frequency of 34Hz.
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 V8 and Paradigm Defiance V10 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 V8's and Paradigm Defiance V10's external dimensions. Paradigm Defiance V8 has external dimensions of 361.0 x 326.0 x 399.0mm (14-3/16inch x 12-13/16inch x 15-11/16inch) whereas Paradigm Defiance V10 has external dimensions of 397.0 x 362.0 x 435.0mm (15-5/8inch x 14-1/4inch x 17-1/8inch).
Paradigm Defiance V10 is clearly the larger of the two speakers. Its body is 36mm wider, 36mm taller and 36mm deeper than Paradigm Defiance V8.

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 V8 is approximately 1300.7cm2 / 201.6inch2 and base area of the Paradigm Defiance V10 is approximately 1574.7cm2 / 244.1inch2. The Defiance V8 requires 17% less surface area than the Defiance V10 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 V8 weighs 12.05kg / 26.5lbs and the Paradigm Defiance V10 weighs 15.23kg / 33.5lbs. This makes the Defiance V10 26% heavier than the Defiance V8.
Here is a comparison of how Defiance V8 and Defiance V10'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.
Paradigm Defiance V10 needs about 21% more floor area. Paradigm Defiance V10 stands 36mm further into the room. Paradigm Defiance V10 is 36mm taller.

Siblings in Paradigm's Defiance range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | B | Paradigm Defiance V10 goes deeper - 29Hz against 34Hz. A real difference, though most music has little content below 34Hz. |
| Amplifier power | B | Paradigm Defiance V10 has the bigger amplifier - 120W against 75W RMS, about 2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Paradigm Defiance V10 moves more air: 10" against 8" 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. |
| Wireless option | depends | Only Paradigm Defiance V10 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 V8 is about 25% 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 V8 costs less - $480 against $679, about 29% less. |
A Paradigm Defiance V8 B Paradigm Defiance V10
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: Paradigm Defiance V10 measures better, Paradigm Defiance V8 costs about 29% less. In a normal room, placement will make a bigger difference than the gap between these two.
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.
