In this review, we will be comparing SW-15 and PB-3000, two Powered Subwoofer speakers from Wharfedale and SVS. 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 SW-15 and SVS PB-3000 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 SW-15and SVS PB-3000 have a single woofer setup however the Wharfedale SW-15's woofer is 15-inch whereas the SVS PB-3000 features a 13-inch woofer.
Frequency Response
SW-15 has a frequency range of 30-120 Hz whereas PB-3000 has a frequency range of 16-200 Hz. With a minimum frequency of 16Hz, the PB-3000 can go significantly deeper on the low side and provide stronger bass compared to the SW-15's min frequency of 30Hz.
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 SW-15 and SVS PB-3000 have Bass Reflex type cabinets. 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 SW-15's and SVS PB-3000's external dimensions. 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) whereas SVS PB-3000 has external dimensions of 558.0 x 466.0 x 661.0mm (21-15/16 x 18-5/16 x 26inch).
SVS PB-3000 is 27mm narrower and 12mm shorter than Wharfedale SW-15 but it is also 46mm deeper.
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.
Near-identical footprints. SVS PB-3000 is 46mm deeper, so it stands that much further out from the wall. Wharfedale SW-15 is 12mm 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 SW-15 is approximately 3032.0cm2 / 470.0inch2 and base area of the SVS PB-3000 is approximately 3080.3cm2 / 477.4inch2. The SW-15 requires 2% less surface area than the PB-3000 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 SW-15 weighs 31.57kg / 69.5lbs and the SVS PB-3000 weighs 37.36kg / 82.2lbs. This makes the PB-3000 18% heavier than the SW-15.
Here is a comparison of how SW-15 and PB-3000's weights compare with the average, max and min weights in Powered Subwoofer class.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | SVS PB-3000 goes deeper - 16Hz against 30Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS PB-3000 has the bigger amplifier - 800W against 400W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Wharfedale SW-15 moves more air: 15" against 13" is 1.33x the cone area, not the 1.15x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Wireless option | depends | Only SVS PB-3000 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Warranty | B | SVS PB-3000 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 SW-15 costs less - $1,199 against $1,600, about 25% less. |
A Wharfedale SW-15 B SVS PB-3000
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: SVS PB-3000 measures better, Wharfedale SW-15 costs about 25% less. In a normal room, placement will make a bigger difference than the gap between these two.
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.
