In this review, we will be comparing RP-1600CSW and Defiance X10, two Powered Subwoofer speakers from Klipsch and 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 Klipsch RP-1600CSW and Paradigm Defiance X10 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 Klipsch RP-1600CSWand Paradigm Defiance X10 have a single woofer setup however the Klipsch RP-1600CSW's woofer is 16-inch whereas the Paradigm Defiance X10 features a 10-inch woofer.
Frequency Response
RP-1600CSW has a frequency range of 14.5-175 Hz whereas Defiance X10 has a frequency range of 29-240 Hz. With a minimum frequency of 15Hz, the RP-1600CSW can go significantly deeper on the low side and provide stronger bass compared to the Defiance X10's min frequency of 29Hz.
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 Klipsch RP-1600CSW has a Acoustic Suspension type cabinet. 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. On the other hand the Paradigm Defiance X10 have Bass Reflex type enclosure. 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 Klipsch RP-1600CSW's and Paradigm Defiance X10's external dimensions. Klipsch RP-1600CSW has external dimensions of 488.2 x 465.6 x 465.6mm (19.22inch x 18.33inch x 18.33inch) whereas 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).
Klipsch RP-1600CSW is clearly the larger of the two speakers. Its body is 82.6mm wider, 70.2mm taller and 12.6mm deeper than Paradigm Defiance X10.
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 RP-1600CSW needs about 25% more floor or shelf area. Klipsch RP-1600CSW is 70mm 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 Klipsch RP-1600CSW is approximately 2167.8cm2 / 336.0inch2 and base area of the Paradigm Defiance X10 is approximately 1735.0cm2 / 268.9inch2. The RP-1600CSW requires 25% more surface area than the Defiance X10 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 Klipsch RP-1600CSW weighs 35.74kg / 78.6lbs and the Paradigm Defiance X10 weighs 19.09kg / 42lbs. This makes the RP-1600CSW 87% heavier than the Defiance X10.
Here is a comparison of how RP-1600CSW and Defiance X10'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 | Klipsch RP-1600CSW goes deeper - 15Hz against 29Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | Klipsch RP-1600CSW has the bigger amplifier - 800W against 300W RMS, about 4.3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1600CSW moves more air: 16" against 10" is 2.56x the cone area, not the 1.6x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Klipsch RP-1600CSW is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; 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. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | B | Paradigm Defiance X10 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. |
| Cabinet size | depends | Paradigm Defiance X10 is about 31% 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 X10 costs less - $1,199 against $1,500, about 20% less. |
A Klipsch RP-1600CSW B Paradigm Defiance X10
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: Klipsch RP-1600CSW measures better, Paradigm Defiance X10 costs about 20% 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, Klipsch RP-1600CSW is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, Paradigm Defiance X10 is the only one of these two you can connect at all.
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.
