In this review, we will be comparing Debut S10 2 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 Debut S10 2 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.ELAC Debut S10 2and B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Debut S10 2 has a frequency range of 35-150 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 27Hz, the ASW610 can go significantly deeper on the low side and provide stronger bass compared to the Debut S10 2's min frequency of 35Hz.
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 Debut S10 2's and B&W ASW610's external dimensions. ELAC Debut S10 2 has external dimensions of 368.3 x 344.5 x 379.4mm () 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 32.5mm narrower and 47.3mm shorter than ELAC Debut S10 2 but it is also 14.6mm deeper.
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 Debut S10 2 is approximately 1307.0cm2 / 202.6inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Debut S10 2 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 ELAC Debut S10 2 weighs 13.02kg / 28.6lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Debut S10 2 4% heavier than the ASW610.
Here is a comparison of how Debut S10 2 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.

A ported 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 | B | B&W ASW610 goes deeper - 27Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | B | B&W ASW610 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 | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | ELAC Debut S10 2 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; 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. |
| Cabinet size | depends | B&W ASW610 is about 18% 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 | ELAC Debut S10 2 carries 3 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 | A | ELAC Debut S10 2 costs less - $399 against $899, about 56% less. |
A ELAC Debut S10 2 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 is ahead, but on only 1 of the measured areas, and it costs about 125% more. ELAC Debut S10 2 is the sensible buy unless your room is large enough to need the extra. Films or music? If this is mainly a home cinema, ELAC Debut S10 2 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. 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 $399 each, two ELAC Debut S10 2 cost about $798 against $899 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.
