In this review, we will be comparing Dynamo 800X and ASW610, two Powered Subwoofer speakers from MartinLogan 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 MartinLogan 800X 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.MartinLogan 800Xand B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Dynamo 800X has a frequency range of 24-200 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 24Hz, the Dynamo 800X can go slightly deeper then the ASW610's min frequency of 27Hz.
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 MartinLogan 800X and B&W ASW610 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 MartinLogan 800X's and B&W ASW610's external dimensions. MartinLogan 800X has external dimensions of 351.0 x 318.0 x 350.0mm (13-13/16 x 12-1/2 x 13-3/4inch) 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 6mm narrower and 30mm shorter than MartinLogan 800X but it is also 44mm 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 MartinLogan 800X is approximately 1113.0cm2 / 172.5inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The Dynamo 800X requires 9% less surface area than the ASW610 which gives it a small advantage 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 MartinLogan 800X weighs 13.64kg / 30lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the Dynamo 800X 9% heavier than the ASW610.
Here is a comparison of how Dynamo 800X 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.
B&W ASW610 needs about 10% more floor area. B&W ASW610 stands 44mm further into the room. MartinLogan 800X is 30mm 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 | A | MartinLogan 800X goes deeper - 24Hz against 27Hz. A real difference, though most music has little content below 27Hz. |
| Amplifier power | A | MartinLogan 800X has the bigger amplifier - 300W against 200W RMS, about 1.8dB 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 | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Wireless option | depends | Only MartinLogan 800X 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 | MartinLogan 800X fires front/down and B&W ASW610 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. |
| Warranty | A | MartinLogan 800X 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 | evenly matched | Priced within a few per cent of each other. |
A MartinLogan 800X 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?
MartinLogan 800X has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is.
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.
