In this review, we will be comparing RP-1200CSW and DB4S, two Powered Subwoofer speakers from Klipsch 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 Klipsch RP-1200CSW and B&W DB4S 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-1200CSWand B&W DB4S have a single woofer setup however the Klipsch RP-1200CSW's woofer is 12-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
RP-1200CSW has a frequency range of 17-160 Hz whereas DB4S has a frequency range of 10-350 Hz. With a minimum frequency of 10Hz, the DB4S can go significantly deeper on the low side and provide stronger bass compared to the RP-1200CSW's min frequency of 17Hz.
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 Klipsch RP-1200CSW and B&W DB4S have Acoustic Suspension type cabinets. 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 Klipsch RP-1200CSW's and B&W DB4S's external dimensions. Klipsch RP-1200CSW has external dimensions of 399.5 x 376.9 x 416.1mm (15.73inch x 14.84inch x 16.38inch) whereas B&W DB4S has external dimensions of 375.0 x 362.0 x 434.0mm (14-3/4 x 14-1/4 x 17-1/16inch).
B&W DB4S is 14.9mm narrower and 24.5mm shorter than Klipsch RP-1200CSW but it is also 17.9mm deeper.
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-1200CSW is approximately 1568.3cm2 / 243.1inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The RP-1200CSW requires 0% less surface area than the DB4S 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 Klipsch RP-1200CSW weighs 21.64kg / 47.6lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 20% heavier than the RP-1200CSW.
Here is a comparison of how RP-1200CSW and DB4S'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.
Near-identical footprints. B&W DB4S stands 18mm further into the room. Klipsch RP-1200CSW is 25mm taller.

Different price classes - B&W DB4S costs roughly 2.6x what Klipsch RP-1200CSW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | B&W DB4S goes deeper - 10Hz against 17Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | B&W DB4S has the bigger amplifier - 1000W against 400W RMS, about 4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1200CSW 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Wireless option | depends | Only Klipsch RP-1200CSW 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. |
| Price | A | Klipsch RP-1200CSW costs less - $850 against $2,199, about 61% less. |
A Klipsch RP-1200CSW B B&W DB4S
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?
B&W DB4S is ahead, but on only 1 of the measured areas, and it costs about 2.6x the price. Klipsch RP-1200CSW is the sensible buy unless your room is large enough to need the extra. 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 $850 each, two Klipsch RP-1200CSW cost about $1,700 against $2,199 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.
