In this review, we will be comparing R-101SW and Windsor 10, 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 10 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.Klipsch R-101SWand KLH Windsor 10 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
R-101SW has a frequency range of 29.5-160 Hz whereas Windsor 10 has a frequency range of 32-150 Hz. With a minimum frequency of 30Hz, the R-101SW can go slightly deeper then the Windsor 10'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
Both Klipsch R-101SW and KLH Windsor 10 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 10'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 10 has external dimensions of 397.0 x 337.0 x 450.0mm (15-5/8 x 13-1/4 x 17-11/16inch).
KLH Windsor 10 is 21mm narrower and 79mm less deeper than Klipsch R-101SW but it is also 27mm 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 R-101SW is approximately 1893.8cm2 / 293.5inch2 and base area of the KLH Windsor 10 is approximately 1516.5cm2 / 235.1inch2. The R-101SW requires 25% more surface area than the Windsor 10 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 R-101SW weighs 13.91kg / 30.6lbs and the KLH Windsor 10 weighs 14.78kg / 32.5lbs. This makes the Windsor 10 6% heavier than the R-101SW.
Here is a comparison of how R-101SW and Windsor 10'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.
Klipsch R-101SW needs about 25% more floor area. Klipsch R-101SW stands 79mm further into the room. KLH Windsor 10 is 27mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (30Hz vs 32Hz). |
| Amplifier power | evenly matched | Much the same amplifier (150W vs 150W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Price | A | Klipsch R-101SW costs less - $499 against $600, about 17% less. |

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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it.
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.
