In this review, we will be comparing WH D10 and SW-15, two Powered Subwoofer speakers by Wharfedale. 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 Wharfedale SW-15 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 Wharfedale SW-15 have a single woofer setup however the Wharfedale WH-D10's woofer is 10-inch whereas the Wharfedale SW-15 features a 15-inch woofer.
Frequency Response
WH D10 has a frequency range of 35-150 Hz whereas SW-15 has a frequency range of 30-120 Hz. With a minimum frequency of 30Hz, the SW-15 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 Wharfedale SW-15 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 Wharfedale SW-15'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 Wharfedale SW-15 has external dimensions of 570.0 x 493.0 x 615.0mm (22-7/16inch x 19-3/8inch x 24-3/16inch).
Wharfedale SW-15 is clearly the larger of the two speakers. Its body is 160mm wider, 177mm taller and 221mm 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.
Wharfedale SW-15 needs about 131% more floor or shelf area. Wharfedale SW-15 is 221mm deeper, so it stands that much further out from the wall. Wharfedale SW-15 is 177mm 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 Wharfedale SW-15 is approximately 3032.0cm2 / 470.0inch2. The WH D10 requires 57% less surface area than the SW-15 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 Wharfedale SW-15 weighs 31.57kg / 69.5lbs. This makes the SW-15 126% heavier than the WH D10.
Here is a comparison of how WH D10 and SW-15'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 | Wharfedale SW-15 goes deeper - 30Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | B | Wharfedale SW-15 has the bigger amplifier - 400W against 150W RMS, about 4.3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Wharfedale SW-15 moves more air: 15" against 10" is 2.25x the cone area, not the 1.5x 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; Wharfedale SW-15 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 70% 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 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | Wharfedale WH-D10 costs less - $699 against $1,199, about 42% less. |
A Wharfedale WH-D10 B Wharfedale SW-15
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: Wharfedale SW-15 measures better, Wharfedale WH-D10 costs about 42% 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, Wharfedale SW-15 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. 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 $699 each, two Wharfedale WH-D10 cost about $1,398 against $1,199 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.
