In this review, we will be comparing SubSeries BP8 and ASW610, two Powered Subwoofer speakers from PSB 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 PSB SubSeries BP8 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 PSB SubSeries BP8and B&W ASW610 have a single woofer setup however the PSB SubSeries BP8's woofer is 8-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
SubSeries BP8 has a frequency range of 25-150 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 25Hz, the SubSeries BP8 can go slightly deeper then 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
Both PSB SubSeries BP8 and B&W ASW610 have Acoustic Suspension type cabinets. 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 PSB SubSeries BP8's and B&W ASW610's external dimensions. PSB SubSeries BP8 has external dimensions of 355 x 330 x 330mm (14 x 13 x 13 inch) 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).
B&W ASW610 is 18mm narrower and 34mm shorter than PSB SubSeries BP8 but it is also 64mm 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.
B&W ASW610 needs about 13% more floor or shelf area. B&W ASW610 is 64mm deeper, so it stands that much further out from the wall. PSB SubSeries BP8 is 34mm 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 PSB SubSeries BP8 is approximately 1089.0cm2 / 168.8inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The SubSeries BP8 requires 11% less surface area than the ASW610 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 PSB SubSeries BP8 weighs 19.10kg / 42lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the SubSeries BP8 52% heavier than the ASW610.
Here is a comparison of how SubSeries BP8 and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - PSB SubSeries BP8 costs roughly 1.7x what B&W ASW610 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (25Hz vs 27Hz). |
| Amplifier power | A | PSB SubSeries BP8 has the bigger amplifier - 500W against 200W RMS, about 4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | B&W ASW610 moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Warranty | B | B&W ASW610 carries 2 years on parts against 1 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 $1,499, about 40% less. |
A PSB SubSeries BP8 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?
B&W ASW610 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. 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 $899 each, two B&W ASW610 cost about $1,798 against $1,499 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.
