In this review, we will be comparing R-101SW and Windsor 12, two Powered Subwoofer speakers from Klipsch and KLH. 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 R-101SW and KLH Windsor 12 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 R-101SWand KLH Windsor 12 have a single woofer setup however the Klipsch R-101SW's woofer is 10-inch whereas the KLH Windsor 12 features a 12-inch woofer.
Frequency Response
R-101SW has a frequency range of 29.5-160 Hz whereas Windsor 12 has a frequency range of 30-160 Hz.
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 R-101SW and KLH Windsor 12 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 Klipsch R-101SW's and KLH Windsor 12's external dimensions. 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) whereas KLH Windsor 12 has external dimensions of 455.0 x 401.0 x 521.0mm (17-7/8 x 15-3/4 x 20-1/2inch).
Klipsch R-101SW is 43mm narrower and 85mm shorter than KLH Windsor 12 but it is also 8mm 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 R-101SW is approximately 1893.8cm2 / 293.5inch2 and base area of the KLH Windsor 12 is approximately 2089.2cm2 / 323.8inch2. The R-101SW requires 9% less surface area than the Windsor 12 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 R-101SW weighs 13.91kg / 30.6lbs and the KLH Windsor 12 weighs 20.19kg / 44.4lbs. This makes the Windsor 12 45% heavier than the R-101SW.
Here is a comparison of how R-101SW and Windsor 12'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.
KLH Windsor 12 needs about 10% more floor area. KLH Windsor 12 is 85mm taller.

Different price classes - KLH Windsor 12 costs roughly 1.6x what Klipsch R-101SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (30Hz vs 30Hz). |
| Amplifier power | B | KLH Windsor 12 has the bigger amplifier - 200W against 150W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | KLH Windsor 12 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 ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Klipsch R-101SW is about 26% 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 | Klipsch R-101SW costs less - $499 against $800, about 38% less. |
A Klipsch R-101SW B KLH Windsor 12
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: KLH Windsor 12 measures better, Klipsch R-101SW costs about 38% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $800 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.
