In this review, we will be comparing WH D8 and R-101SW, two Powered Subwoofer speakers from Wharfedale 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 Wharfedale WH-D8 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.Both Wharfedale WH-D8and Klipsch R-101SW have a single woofer setup however the Wharfedale WH-D8's woofer is 8-inch whereas the Klipsch R-101SW features a 10-inch woofer.
Frequency Response
WH D8 has a frequency range of 40-120 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 30Hz, the R-101SW can go significantly deeper on the low side and provide stronger bass compared to the WH D8's min frequency of 40Hz.
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 Wharfedale WH-D8 has a Infinite Baffle type cabinet. On the other hand the Klipsch R-101SW 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 Wharfedale WH-D8's and Klipsch R-101SW's external dimensions. Wharfedale WH-D8 has external dimensions of 328.0 x 268.0 x 322.0mm (12-15/16 x 10-9/16 x 12-11/16inch) 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 90mm wider, 42mm taller and 207mm deeper than Wharfedale WH-D8.
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 119% more floor or shelf area. Klipsch R-101SW is 207mm deeper, so it stands that much further out from the wall. Klipsch R-101SW is 42mm 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 Wharfedale WH-D8 is approximately 863.0cm2 / 133.8inch2 and base area of the Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The WH D8 requires 54% 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 Wharfedale WH-D8 weighs 7.50kg / 16.5lbs and the Klipsch R-101SW weighs 13.91kg / 30.6lbs. This makes the R-101SW 85% heavier than the WH D8.
Here is a comparison of how WH D8 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 | B | Klipsch R-101SW goes deeper - 30Hz against 40Hz. A real difference, though most music has little content below 40Hz. |
| Amplifier power | B | Klipsch R-101SW has the bigger amplifier - 150W against 70W RMS, about 3.3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Klipsch R-101SW moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Wharfedale WH-D8 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 | Wharfedale WH-D8 is about 60% 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 | Wharfedale WH-D8 carries 5 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 | A | Wharfedale WH-D8 costs less - $449 against $499, about 10% less. |
A Wharfedale WH-D8 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: Klipsch R-101SW measures better, Wharfedale WH-D8 costs about 10% 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, Wharfedale WH-D8 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - Wharfedale WH-D8 is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
