In this review, we will be comparing Bronze W10 and ASW610, 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 Bronze W10 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.Monitor Audio Bronze W10and B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Bronze W10 has a frequency range of 29-150 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 27Hz, the ASW610 can go slightly deeper then the Bronze W10's min frequency of 29Hz.
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 Monitor Audio Bronze W10 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 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 Monitor Audio Bronze W10's and B&W ASW610's external dimensions. Monitor Audio Bronze W10 has external dimensions of 361.0 x 321.0 x 405.0mm (14-3/16 x 12-5/8 x 15-15/16inch) 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).
Monitor Audio Bronze W10 is clearly the larger of the two speakers. Its body is 9mm wider, 40mm taller and 11mm deeper than B&W ASW610.

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 Bronze W10 is approximately 1300.1cm2 / 201.5inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Bronze W10 requires 6% 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 Monitor Audio Bronze W10 weighs 13.44kg / 29.6lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Bronze W10 7% heavier than the ASW610.
Here is a comparison of how Bronze W10 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.
Near-identical footprints. Monitor Audio Bronze W10 is 40mm taller.

A passive radiator 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 | evenly matched | Effectively the same reach (29Hz vs 27Hz). |
| Amplifier power | evenly matched | Much the same amplifier (220W vs 200W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | Monitor Audio Bronze W10 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; 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. |
| Warranty | A | Monitor Audio Bronze 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 ASW610 costs less - $899 against $975, about 8% less. |
A Monitor Audio Bronze W10 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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. Films or music? If this is mainly a home cinema, Monitor Audio Bronze W10 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.
