In this review, we will be comparing WH D10 and SPL-120, 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-D10 and Klipsch SPL-120 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-D10and Klipsch SPL-120 have a single woofer setup however the Wharfedale WH-D10's woofer is 10-inch whereas the Klipsch SPL-120 features a 12-inch woofer.
Frequency Response
WH D10 has a frequency range of 35-150 Hz whereas SPL-120 has a frequency range of 24-125 Hz. With a minimum frequency of 24Hz, the SPL-120 can go significantly deeper on the low side and provide stronger bass compared to the WH D10's min frequency of 35Hz.
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-D10 has a Infinite Baffle type cabinet. On the other hand the Klipsch SPL-120 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-D10's and Klipsch SPL-120's external dimensions. Wharfedale WH-D10 has external dimensions of 393.0 x 333.0 x 394.0mm (15-1/2 x 13-1/8 x 15-1/2inch) whereas Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm (17-11/16 x 14-3/4 x 21-1/4inch).
Klipsch SPL-120 is clearly the larger of the two speakers. Its body is 42mm wider, 57mm taller and 146mm deeper than Wharfedale WH-D10.
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 SPL-120 needs about 54% more floor or shelf area. Klipsch SPL-120 is 146mm deeper, so it stands that much further out from the wall. Klipsch SPL-120 is 57mm 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-D10 is approximately 1312.0cm2 / 203.4inch2 and base area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2. The WH D10 requires 35% less surface area than the SPL-120 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-D10 weighs 14.00kg / 30.8lbs and the Klipsch SPL-120 weighs 20.45kg / 45lbs. This makes the SPL-120 46% heavier than the WH D10.
Here is a comparison of how WH D10 and SPL-120'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 SPL-120 goes deeper - 24Hz against 35Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | B | Klipsch SPL-120 has the bigger amplifier - 300W against 150W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Klipsch SPL-120 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 | depends | Wharfedale WH-D10 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch SPL-120 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-D10 is about 43% 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-D10 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 | B | Klipsch SPL-120 costs less - $499 against $699, about 29% less. |
A Wharfedale WH-D10 B Klipsch SPL-120
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?
Klipsch SPL-120 is the easier recommendation: it leads on most of the measured areas and costs less. Take Wharfedale WH-D10 if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, Klipsch SPL-120 will hit harder for the money; if it is mainly for music in a normal-sized room, Wharfedale WH-D10 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - Wharfedale WH-D10 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.
