In this review, we will be comparing DS103 and ASW608, 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 DS103 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 ELAC DS103and B&W ASW608 have a single woofer setup however the ELAC DS103's woofer is 10-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
DS103 has a frequency range of 31-150 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 31Hz, the DS103 can go slightly deeper then 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 ELAC DS103's and B&W ASW608's external dimensions. ELAC DS103 has external dimensions of 325.4 x 311.2 x 392.1mm () 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).
ELAC DS103 is clearly the larger of the two speakers. Its body is 50.2mm wider, 53.4mm taller and 42.1mm 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 ELAC DS103 is approximately 1220.2cm2 / 189.1inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The DS103 requires 34% 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 ELAC DS103 weighs 10.30kg / 22.7lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the DS103 16% heavier than the ASW608.
Here is a comparison of how DS103 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.
ELAC DS103 needs about 34% more floor area. ELAC DS103 stands 42mm further into the room. ELAC DS103 is 53mm 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 (31Hz vs 32Hz). |
| Amplifier power | B | B&W ASW608 has the bigger amplifier - 200W against 100W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC DS103 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 37% 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 ASW608 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 DS103 costs less - $479 against $599, about 20% less. |
A ELAC DS103 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: B&W ASW608 measures better, ELAC DS103 costs about 20% less. In a normal room, placement will make a bigger difference than the gap between these two. 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.
