In this review, we will be comparing PB-2000 Pro and ASW610, two Powered Subwoofer speakers from SVS and Bowers Wilkins. 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 SVS PB-2000 Pro and B&W ASW610 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 SVS PB-2000 Proand B&W ASW610 have a single woofer setup however the SVS PB-2000 Pro's woofer is 12-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
PB-2000 Pro has a frequency range of 16-290 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 16Hz, the PB-2000 Pro can go significantly deeper on the low side and provide stronger bass compared to the ASW610's min frequency of 27Hz.
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 SVS PB-2000 Pro has a Bass Reflex type cabinet. 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. On the other hand the B&W ASW610 have Acoustic Suspension type enclosure. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported 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 SVS PB-2000 Pro's and B&W ASW610's external dimensions. SVS PB-2000 Pro has external dimensions of 534.0 x 442.0 x 609.0mm (21 x 17-3/8 x 23-15/16inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm (12-5/8 x 12-1/4 x 15-1/2inch).
SVS PB-2000 Pro is clearly the larger of the two speakers. Its body is 130mm wider, 213mm taller and 215mm deeper than B&W ASW610.
Below you can see the front view size comparison of SVS PB-2000 Pro and B&W ASW610 in scale.

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 SVS PB-2000 Pro is approximately 2691.8cm2 / 417.2inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The PB-2000 Pro requires 119% more surface area than the ASW610 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 SVS PB-2000 Pro weighs 29.45kg / 64.8lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the PB-2000 Pro 135% heavier than the ASW610.
Here is a comparison of how PB-2000 Pro and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers 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 floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
SVS PB-2000 Pro needs about 119% more floor area. SVS PB-2000 Pro stands 215mm further into the room. SVS PB-2000 Pro is 213mm taller.

A ported subwoofer against a sealed 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 | SVS PB-2000 Pro goes deeper - 16Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS PB-2000 Pro has the bigger amplifier - 550W against 200W RMS, about 4.4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS PB-2000 Pro 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 | SVS PB-2000 Pro is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; B&W ASW610 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. 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 | B | B&W ASW610 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. |
| Wireless option | depends | Only SVS PB-2000 Pro 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. |
| Cabinet size | depends | B&W ASW610 is about 73% 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 | SVS PB-2000 Pro 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 | B&W ASW610 costs less - $899 against $1,100, about 18% less. |
A SVS PB-2000 Pro B B&W ASW610
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?
SVS PB-2000 Pro leads across most of the measured areas for a modest premium, so it is the easier pick if the budget stretches. B&W ASW610 is the one to take if it does not. Films or music? If this is mainly a home cinema, SVS PB-2000 Pro will hit harder for the money; if it is mainly for music in a normal-sized room, B&W ASW610 is usually the easier one to make sound right. Check your amplifier first: if it has no subwoofer or preamp output, B&W ASW610 is the only one of these two you can connect at all.
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.
