In this review, we will be comparing Nova 12 and A120P, two Powered Subwoofer speakers from Wharfedale and JBL. 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 12 and JBL Stage A120P 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.Wharfedale Nova 12and JBL Stage A120P have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Nova 12 has a frequency range of 28 Hz (-6dB) whereas A120P has a frequency range of 32-150 Hz. With a minimum frequency of 28Hz, the Nova 12 can go slightly deeper then the A120P'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
The Wharfedale Nova 12 has a Passive Radiator type cabinet. 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. On the other hand the JBL Stage A120P have Bass reflex type enclosure.
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 12's and JBL Stage A120P's external dimensions. Wharfedale Nova 12 has external dimensions of 443.0 x 435.0 x 487.0mm (17.44inch x 17.13inch x 19.17inch) whereas JBL Stage A120P has external dimensions of 415.0 x 393.0 x 475.0mm (16-5/16 x 15-7/16 x 18-11/16inch).
Wharfedale Nova 12 is clearly the larger of the two speakers. Its body is 42mm wider, 28mm taller and 12mm deeper than JBL Stage A120P.
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 12 needs about 13% more floor or shelf area. Wharfedale Nova 12 is 28mm 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 12 is approximately 2118.5cm2 / 328.4inch2 and base area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2. The Nova 12 requires 13% more surface area than the A120P 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 Wharfedale Nova 12 weighs 29.30kg / 64.5lbs and the JBL Stage A120P weighs 18.68kg / 41.1lbs. This makes the Nova 12 57% heavier than the A120P.
Here is a comparison of how Nova 12 and A120P's weights compare with the average, max and min weights in Powered Subwoofer class.

A passive radiator 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 | A | Wharfedale Nova 12 goes deeper - 28Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | evenly matched | Much the same amplifier (280W vs 250W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | Wharfedale Nova 12 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; JBL Stage A120P 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. |
| Speaker-level inputs | A | Wharfedale Nova 12 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | JBL Stage A120P is about 17% 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 | B | JBL Stage A120P costs less - $300 against $1,599, about 81% less. |
A Wharfedale Nova 12 B JBL Stage A120P
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 12 measures better, JBL Stage A120P costs about 81% less. In a normal room, placement will make a bigger difference than the gap between these two. Check your amplifier first: if it has no subwoofer or preamp output, Wharfedale Nova 12 is the only one of these two you can connect at all. 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 $300 each, two JBL Stage A120P cost about $600 against $1,599 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.
