In this review, we will be comparing Muro SUB2020 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 Muro SUB2020 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 Muro SUB2020and B&W ASW608 have a single woofer setup however the ELAC Muro SUB2020's woofer is 10-inch whereas the B&W ASW608 features a 8-inch woofer.
Frequency Response
Muro SUB2020 has a frequency range of 28-200 Hz whereas ASW608 has a frequency range of 32-140 Hz. With a minimum frequency of 28Hz, the Muro SUB2020 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.

Cabinet Type
Both ELAC Muro SUB2020 and B&W ASW608 have Acoustic Suspension type cabinets. 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 ELAC Muro SUB2020's and B&W ASW608's external dimensions. ELAC Muro SUB2020 has external dimensions of 399.0 x 185.0 x 515.0mm (15-11/16 x 7-1/4 x 20-1/4inch) 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).
B&W ASW608 is 127mm shorter and 165mm less deeper than ELAC Muro SUB2020 but it is also 76mm wider.

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 Muro SUB2020 is approximately 952.8cm2 / 147.7inch2 and base area of the B&W ASW608 is approximately 913.5cm2 / 141.6inch2. The Muro SUB2020 requires 4% 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 Muro SUB2020 weighs 12.73kg / 28lbs and the B&W ASW608 weighs 8.86kg / 19.5lbs. This makes the Muro SUB2020 44% heavier than the ASW608.
Here is a comparison of how Muro SUB2020 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.
Near-identical footprints. ELAC Muro SUB2020 stands 165mm further into the room. ELAC Muro SUB2020 is 127mm taller.

Different price classes - ELAC Muro SUB2020 costs roughly 1.7x what B&W ASW608 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | ELAC Muro SUB2020 goes deeper - 28Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | A | ELAC Muro SUB2020 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. |
| Speaker-level inputs | B | B&W ASW608 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. |
| Wireless option | depends | Only ELAC Muro SUB2020 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Driver placement | depends | ELAC Muro SUB2020 fires side or down and B&W ASW608 fires front. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | B&W ASW608 is about 35% 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 | B | B&W ASW608 costs less - $599 against $1,000, about 40% less. |
A ELAC Muro SUB2020 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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. Check your amplifier first: if it has no subwoofer or preamp output, B&W ASW608 is the only one of these two you can connect at all. 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 $1,000 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.
