In this review, we will be comparing Nova 8 and Nova 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 Nova 8 and Wharfedale Nova 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 Nova 8and Wharfedale Nova 15 have a single woofer setup however the Wharfedale Nova 8's woofer is 8-inch whereas the Wharfedale Nova 15 features a 15-inch woofer.
Frequency Response
Nova 8 has a frequency range of 33 Hz (-6dB) whereas Nova 15 has a frequency range of 28 Hz (-6dB). With a minimum frequency of 28Hz, the Nova 15 can go significantly deeper on the low side and provide stronger bass compared to the Nova 8's min frequency of 33Hz.
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 Wharfedale Nova 8 and Wharfedale Nova 15 have Passive Radiator type cabinets. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or 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 Nova 8's and Wharfedale Nova 15's external dimensions. Wharfedale Nova 8 has external dimensions of 348.0 x 320.0 x 361.0mm (13.7inch x 12.6inch x 14.21inch) whereas Wharfedale Nova 15 has external dimensions of 549.0 x 540.0 x 607.0mm (21.61inch x 21.26inch x 23.9inch).
Wharfedale Nova 15 is clearly the larger of the two speakers. Its body is 220mm wider, 201mm taller and 246mm deeper than Wharfedale Nova 8.
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 Nova 15 needs about 184% more floor or shelf area. Wharfedale Nova 15 is 246mm deeper, so it stands that much further out from the wall. Wharfedale Nova 15 is 201mm 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 Nova 8 is approximately 1155.2cm2 / 179.1inch2 and base area of the Wharfedale Nova 15 is approximately 3277.8cm2 / 508.1inch2. The Nova 8 requires 65% less surface area than the Nova 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 Nova 8 weighs 16.30kg / 35.9lbs and the Wharfedale Nova 15 weighs 47.80kg / 105.2lbs. This makes the Nova 15 193% heavier than the Nova 8.
Here is a comparison of how Nova 8 and Nova 15's weights compare with the average, max and min weights in Powered Subwoofer class.

Siblings in Wharfedale's Nova range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | B | Wharfedale Nova 15 goes deeper - 28Hz against 33Hz. A real difference, though most music has little content below 33Hz. |
| Amplifier power | B | Wharfedale Nova 15 has the bigger amplifier - 360W against 200W RMS, about 2.6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Wharfedale Nova 15 moves more air: 15" against 8" is 3.52x the cone area, not the 1.88x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Setup and tuning | evenly matched | The same tuning tools on both (onboard DSP). |
| Cabinet size | depends | Wharfedale Nova 8 is about 78% 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 | Wharfedale Nova 8 costs less - $1,099 against $1,999, about 45% less. |
A Wharfedale Nova 8 B Wharfedale Nova 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 Nova 15 measures better, Wharfedale Nova 8 costs about 45% 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 $1,099 each, two Wharfedale Nova 8 cost about $2,198 against $1,999 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Wharfedale Nova 8 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.
