In this review, we will be comparing Defiance S10 and R-101SW, two Powered Subwoofer speakers from Paradigm and Klipsch. 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 Klipsch R-101SW 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.Paradigm Defiance S10and Klipsch R-101SW have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Defiance S10 has a frequency range of 25-200 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 25Hz, the Defiance S10 can go significantly deeper on the low side and provide stronger bass compared to the R-101SW'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.

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 Klipsch R-101SW's external dimensions. Paradigm Defiance S10 has external dimensions of 338.1 x 342.9 x 425.5mm () whereas Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm (14-9/16inch x 14-1/16inch x 20-13/16inch).
Klipsch R-101SW is clearly the larger of the two speakers. Its body is 15.1mm wider, 31.9mm taller and 103.5mm 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.
Klipsch R-101SW needs about 30% more floor or shelf area. Klipsch R-101SW is 104mm deeper, so it stands that much further out from the wall. Klipsch R-101SW is 32mm 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 Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The Defiance S10 requires 23% less surface area than the R-101SW 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 Klipsch R-101SW weighs 13.91kg / 30.6lbs. This makes the Defiance S10 13% heavier than the R-101SW.
Here is a comparison of how Defiance S10 and R-101SW'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 | A | Paradigm Defiance S10 goes deeper - 25Hz against 30Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | A | Paradigm Defiance S10 has the bigger amplifier - 500W against 150W RMS, about 5.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| 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; Klipsch R-101SW 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 30% 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 S10 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 | Klipsch R-101SW costs less - $499 against $1,200, about 58% less. |
A Paradigm Defiance S10 B Klipsch R-101SW
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 S10 measures better, Klipsch R-101SW costs about 58% 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, Klipsch R-101SW 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 $499 each, two Klipsch R-101SW cost about $998 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.
