In this review, we will be comparing Defiance X10 and ASW608, two Powered Subwoofer speakers from Paradigm and Bowers Wilkins. 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 X10 and B&W ASW608 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 X10and B&W ASW608 have a single woofer setup however the Paradigm Defiance X10's woofer is 10-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
Defiance X10 has a frequency range of 29-240 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 29Hz, the Defiance X10 can go slightly deeper then the ASW608's min frequency of 32Hz.
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 Paradigm Defiance X10 has a Bass Reflex type cabinet. 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. On the other hand the B&W ASW608 have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 X10's and B&W ASW608's external dimensions. Paradigm Defiance X10 has external dimensions of 418.0 x 383.0 x 453.0mm (16-7/16inch x 15-1/16inch x 17-13/16inch) whereas B&W ASW608 has external dimensions of 272.0 x 261.0 x 350.0mm (10-11/16 x 10-1/4 x 13-3/4inch).
Paradigm Defiance X10 is clearly the larger of the two speakers. Its body is 122mm wider, 146mm taller and 103mm deeper than B&W ASW608.

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 X10 is approximately 1735.0cm2 / 268.9inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Defiance X10 requires 90% more surface area than the ASW608 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 Paradigm Defiance X10 weighs 19.09kg / 42lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Defiance X10 115% heavier than the ASW608.
Here is a comparison of how Defiance X10 and ASW608'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 X10 needs about 90% more floor area. Paradigm Defiance X10 stands 103mm further into the room. Paradigm Defiance X10 is 146mm taller.

A ported subwoofer against a sealed 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 | Paradigm Defiance X10 goes deeper - 29Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | Paradigm Defiance X10 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Paradigm Defiance X10 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 | depends | Paradigm Defiance X10 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; B&W ASW608 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Wireless option | depends | Only Paradigm Defiance X10 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 | B&W ASW608 is about 66% 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 | A | Paradigm Defiance X10 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 | B | B&W ASW608 costs less - $599 against $1,199, about 50% less. |
A Paradigm Defiance X10 B B&W ASW608
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 X10 measures better, B&W ASW608 costs about 50% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Paradigm Defiance X10 will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW608 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 $599 each, two B&W ASW608 cost about $1,198 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.
