In this review, we will be comparing Vestra W10 and ASW608, two Powered Subwoofer speakers from Monitor Audio 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 Monitor Audio Vestra W10 and B&W ASW608 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 Monitor Audio Vestra W10and B&W ASW608 have a single woofer setup however the Monitor Audio Vestra W10's woofer is 10.0-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
Vestra W10 has a frequency range of 19-200 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 19Hz, the Vestra W10 can go significantly deeper on the low side and provide stronger bass compared to the ASW608'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.

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 Monitor Audio Vestra W10's and B&W ASW608's external dimensions. Monitor Audio Vestra W10 has external dimensions of 342.9 x 330.2 x 403.2mm () whereas B&W ASW608 has external dimensions of 272.0 x 261.0 x 350.0mm (10-11/16 x 10-1/4 x 13-3/4inch).
Monitor Audio Vestra W10 is clearly the larger of the two speakers. Its body is 69.2mm wider, 70.9mm taller and 53.2mm deeper than B&W ASW608.
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 Monitor Audio Vestra W10 is approximately 1331.4cm2 / 206.4inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Vestra W10 requires 46% more surface area than the ASW608 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 Monitor Audio Vestra W10 weighs 13.29kg / 29.2lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Vestra W10 50% heavier than the ASW608.
Here is a comparison of how Vestra W10 and ASW608'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.
Monitor Audio Vestra W10 needs about 46% more floor area. Monitor Audio Vestra W10 stands 53mm further into the room. Monitor Audio Vestra W10 is 71mm taller.

Different price classes - Monitor Audio Vestra W10 costs roughly 1.6x what B&W ASW608 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Monitor Audio Vestra W10 goes deeper - 19Hz against 32Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | Monitor Audio Vestra W10 has the bigger amplifier - 250W against 200W RMS, about 1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Monitor Audio Vestra W10 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. |
| Cabinet size | depends | B&W ASW608 is about 46% 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 | Monitor Audio Vestra W10 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 ASW608 costs less - $599 against $979, about 39% less. |
A Monitor Audio Vestra W10 B B&W ASW608
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: Monitor Audio Vestra W10 measures better, B&W ASW608 costs about 39% 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 $599 each, two B&W ASW608 cost about $1,198 against $979 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - B&W ASW608 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.
