In this review, we will be comparing DS123 and ASW610, two Powered Subwoofer speakers from ELAC 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 ELAC DS123 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 ELAC DS123and B&W ASW610 have a single woofer setup however the ELAC DS123's woofer is 12-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
DS123 has a frequency range of 28-150 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 DS123's min frequency of 28Hz.
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 ELAC DS123's and B&W ASW610's external dimensions. ELAC DS123 has external dimensions of 374.7 x 360.4 x 446.1mm () 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).
ELAC DS123 is clearly the larger of the two speakers. Its body is 48.4mm wider, 53.7mm taller and 52.1mm 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 ELAC DS123 is approximately 1607.7cm2 / 249.2inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The DS123 requires 31% 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 ELAC DS123 weighs 13.70kg / 30.1lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the DS123 9% heavier than the ASW610.
Here is a comparison of how DS123 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.
ELAC DS123 needs about 31% more floor area. ELAC DS123 stands 52mm further into the room. ELAC DS123 is 54mm taller.

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 | evenly matched | Effectively the same reach (28Hz vs 27Hz). |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | A | ELAC DS123 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | B&W ASW610 is about 34% 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 | 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 | A | ELAC DS123 costs less - $599 against $899, about 33% less. |
A ELAC DS123 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. If placement is the constraint - a corner, behind a sofa, under a desk - B&W ASW610 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.
